HISTORY OF THE INSTITUTE

Institute of Chemistry was established on September 1, 1946 by one of the organizers and the permanent director of the Institute for 25 years, was a disciple of the outstanding Russian scholar A.E. Favorsky, Doctor of Chemistry, Academician of Tajik SSR, Honored Scientist of the Tajik SSR, Professor V.I. Nikitin. The government, taking into account the merits of V.I. Nikitin in 1977 awarded him the name of the Institute of Chemistry. From 1971 to 1987 Director of the Institute was elected Academician I.U. Numanov, from 1987 to 2003 Academician U.M. Mirsaidov, and since 2003 till 2014 the Institute is headed by Academician D.H. Khalikov. From April 10, 2014 until now Institute lead by professor Zayniddin Kamarovich Muhidinov.

The main task of the Institute of Chemistry during its creation was a chemical study of natural resources of Tajikistan and the application of the obtained results for the industries of the republic of Tajikistan.

Analyzing the 20-year period of the research activities of the Institute of Chemistry, it should be noted that in the early 90s the Institute was working in a very challenging environment. Began in 1991, the outflow of scientists in the educational, industrial and commercial areas as well as outside of Tajikistan, and continued in subsequent years, until 1998 significantly decreased funding and logistical support to basic research. Due to the outflow of scientists and lack of specialists, and especially with the departure of the leaders of the research, who also were heads of the laboratories, in the period of 1991-1999. Six laboratories have been closed at the Institute. In these circumstances we had to face critical issues of reform of the steel structure, combining topics, focused on solving scientific problems, especially for the needs of the country, search for extra-budgetary funding sources, maintaining existing staff and training of doctors and candidates of sciences.

The subject of the main concerns of the Institute, and the Academy of Sciences, throughout its existence, was the preparation of highly qualified personnel. This work in the second half of the 50-ies of the last century, led by the president of the Academy of Sciences Sulton Umarovich Umarov. It should be noted the exceptional role of scientists USSR Academy of Sciences and Moscow State University M.V. Lomonosov in the preparation of the scientific staff of the Institute for Chemistry. Among them are world famous scientists, such as Academicians I.P. Alimarin, Y. Buslaev, A.P. Vinogradov, G.G Devyatikh, B.P. Zhukov, V.A. Kargin, F.A. Kuznetsov, N.A. Plate, A.B. Ronov, academician of AMS M.D. Mashkovskii, corr. RAS V.P. Shibayev, Professor V.N Vigdorovich, T.N. Dimova, A.B. Kostyanovsky, and many others.

For the preparation of academic staff played an important role in the entry of the Republic of Tajikistan to the coverage zone of VAK Russia and organization at the Institute of Chemistry of the two thesis councils for conferring the degree of Doctor (Chairman - Academician of the Academy of Sciences of the Republic of Tajikistan Mirsaidov U.M.) and Candidate of Sciences (chairman candidate - Corr member of Academy of Sciences of the Republic of Tajikistan Khalikov D.H), which operated from 1991 until the end of 2000, and the last two councils, combined into the doctor's council in four specialties since 2001 until now. Through these efforts, for the period 1991-2010 years the Institute trained 45 doctors and 282 candidates of sciences. This allowed almost completely update the staff of the now existing laboratories and universities to provide highly qualified and various branches of the national economy of the republic.

Solution of personnel matters and repeated wage increase from the government stimulated the formulation of the new studies, particularly those which were necessary for the needs of the republic.

The most important scientific results obtained at the Institute of Chemistry in the last ten-year period include: development of new corrosion-resistant aluminum alloys for the needs of the machine-building complex of the republic; Study of corrosion-electrochemical behavior of iron - aluminum alloys doped with gallium, indium and thallium in a saline environment, which allows you to get both the anode alloys for cathodic protection and corrosion-resistant alloys; established the possibility of using zeolites and granites of Tajikistan as a raw material for the porcelain industry, as well as in the production of coagulants for the purification of drinking water and wastewater; proposed technological scheme of processing of mudstone, zeolites, kaolin clays, danburites, getting cryolite-alumina concentrate from the aluminum industry waste and the local mineral raw materials; extraction technology development of thallium during metallurgical processing of antimony-mercury mine concentrates of Jijikrutsky mineral assets , as well as the study of the flotation of phosphorus ore beneficiation technology Karatag field; the development of combined technologies of processing of gold-antimony-mercury ore deposits Jijikrutsky, refractory gold ores Chore and Tarf; development of inversion- voltammetric methods for determining mercury in natural waters and setting the optimal conditions for the simultaneous determination of micro concentrations copper, lead, bismuth, cadmium and zinc on the mercury-Foil silver electrode in fluoride, barium different purity by stripping voltammeter; testing of conditions the introduction of functional groups in the 1 and 6 position of galactose in the general scheme of obtaining “Linkometsin” drug; receive a number of derivatives triazintion by the reaction of the latter with thionyl chloride and hydrazine hydrate; synthesis method development 2-(5-amino-1,3,4-tiadizol-2-ilsulfid)-6-chlor-7-metil-5-okso-1,3,4-tiadizol[3,2-а]pirimidin; study the reactivity of the amine moiety in the synthesis of new heterocyclic systems; development of the method for determining cholesterol in the blood and other biological fluids by gas-liquid chromatography, which is of great importance for the diagnosis and treatment of diseases of the cardiovascular and hepatobiliary systems.

Developed: a method for removing heavy and toxic elements from the living body using matrix of different low methoxilated pectin. Application of new method for pectin hydrolyzate solution purification by ultra filtration; and method of preparing a binder composition based on cottonseed oil processing (cotton hydra) for use in road construction. For the purpose of drug delivery system (DDS) to the gut, drug encapsulation was conducted in the form of hydrogel microspheres and emulsion micro particles using natural polymers pectin, zein and whey lactoglobulins. Showing DDS prolonged therapeutic effect with a single application and no fluctuations in the concentration of their blood. Experimentally and clinically found that DS have the ability to exert a pronounced bactericidal activity against pathogens of acute intestinal infections. DS in combination with an antibiotic treatment accelerates intestinal infections.

In the last decade the Institute of Chemistry has developed 14 proposals for the use in the industries and enterprises of Tajikistan. Thus seven developments introduced into production. So, on the Tajik Aluminum Plant introduced methods for producing ferrosilicon and iron from waste production to the overall economic effect of about 1 million US dollars. Production of coagulants has been arranged for water purification. On the basis of the Institute of Chemistry developed the technology of cryolite-alumina concentrate waste from the aluminum industry and local minerals (nepheline syenite, siallite and fluorite) Tajik Aluminum Plant was built and put into operation shop for processing aluminum waste. Development of Institute of Chemistry on creation of membranes implemented in PO “Tajiktekstilmash” for mass production of gas meters, and a method for purifying and stabilizing the transparency of wines with local bentonite and polymeric materials at AOOT “Dushanbe”, with the economic effect of 65 thousand somoni. For the Ministry of Defence of the Republic of Tajikistan has developed a technology of neutralization of liquid missile fuel, prepared by complex regulations and carried out their complete disposal; together with Tajikfarminvest based on local medicinal plants developed ointment "Orion" for the treatment of burns and inflammation, as well as technology for producing oil, "Amaranth". Received "Tajikgosstandart" license to conduct analytical work on the eight areas of chemistry. Seven developments of Chemistry Institute have been included in the "Program of introduction of scientific and technological achievements of the results in industrial production of the Republic of Tajikistan for the period 2010-2015.", Approved by the Government of the Republic. Many of the proposals of the Institute of Chemistry included in the list of collaborative innovation work with the Institute of Chemistry companies in Dushanbe, approved by the mayor's office in Dushanbe.

In these years at the Institute of Chemistry held 12 international and republican scientific-practical conferences and seminars. Conducted conferences contributed to the establishment of creative contacts, formulation of joint research and in general had a positive impact on the overall level of research conducted at the Institute. Thus, from 2003 to 2016 Institute of Chemistry through International Centre for Science and Technology (ISTC) made agreements and fulfilled scientific - research works on 10 Project of more than two million dollars. During the same period, the work carried out under grants with the countries of the European Union, NATO, Russia and other countries for more than 200 thousand dollars. In frame of the Fulbright scholarship program funded by US Deptartment of State six PhD scientist of the Institute have visited and carried out joint research work in the different universities of the United States. With the support of the German Academic Exchange Programme were trained ten young scientists who are at the same time to perform the necessary studies on the unique scientific equipment. The presence of extra-budgetary funding, the ability to travel at the expense of the host country sharply raised the level of R&D at the Institute, have increased the number of publications in the prestigious international scientific journals, contributed to the establishment of scientific relations with foreign counterparts, providing the Institute with new modern equipment. Employees of the Institute, especially the younger generation, are parties almost in every major international congresses, conferences, symposia, became members of the organizing committees of many international events and the members of the editorial board of chemical journals.

Currently (2014), in the Institute of Chemistry are functioning eight Laboratories, leading scientific research on the problems of organic, inorganic, physical and analytical chemistry, and macromolecular chemistry.
