VOROZHTSOV, NIKOLAI NIKQLAEVICH (Organic Chemist) 



N. N. Vorozhtsov, son of N. N. Vorozhtsov (1881-1941, or- 

 ganic chemist), was born June 5, 1907. He graduated from the 

 Moscow Technological College in 1928, and from then until 1930 

 he worked in the Laboratory of the Commission on the Study of 

 the Natural Productive Forces of the U.S.S.R. Academy of Sci- 

 ences in Moscow. In 1930-38, he was at the State Institute of 

 High Pressures in Leningrad; in 1938-43 he taught at the 

 Kazakh State University where, in 1939, he was made professor. 

 He was Director of the Scientific Research Institute of Organic 

 Semiproducts and Dyes from 1943 to 1947, and in 1945 was 

 Chairman of the Department of the Moscow Mendeleev Chemico- 

 Technological Institute. In 1958 he was elected a Corresponding 

 Member of the U.S.S.R. Academy of Sciences. He became a 

 member of the Communist Party of the Soviet Union in 1942. 

 He received a Stalin Prize in 1952. 



The investigations of Vorozhtsov are in organic chemistry, 

 technology of organic dyes and intermediates. He investigated 

 exchange reactions of aryl halides, catalytic isomerization, 

 halogen-naphthalenes, halogenation of aromatic and aliphatic 

 compounds, sulfonation and the transformation of sulfo acids. 

 A part of the work of Vorozhtsov deals with the structure of 

 natural products. He supplemented and prepared for publi- 

 cation the 3rd and 4th editions of a well-known monograph of 

 N. N. Vorozhtsov, Sr., "Basis of Synthesis of Intermediate Pro- 

 ducts and Dyes," (3rd ed., 1952). 



As of 1961, Vorozhtsov was the Director of the Institute of 

 Organic Chemistry of the Siberian Branch U.S.S.R. Academy of 

 Sciences.
