Life
Rotinjan studied at the Imperial University of St. Petersburg in the nature department of the physics and mathematics faculty . At WA Kistjakowski he determined the dependence of the heat of solution on the molecular mass . With these results, WA Kistjakowski proposed a new equation for these parameters. After graduating in 1903, he worked at the Chair of Chemistry and Theoretical Electrochemistry at the St. Petersburg Polytechnic Institute . 1904–1907 he was seconded to scientific work in Germany . Rotinjan became known for his investigations into the viscosity of liquid sulfur , which Wilhelm Ostwald used as the basis of his viscosity theory.
In 1918 after the October Revolution , Rotinjan became a lecturer in inorganic chemistry at the University of Tbilisi, which had just been founded . In 1923 he followed a call to the University of Yerevan , which opened in 1921 and which appointed him professor in 1925. In 1930 he moved to the Yerevan Polytechnic Institute . In 1935 he became a member of the Presidium of the Armenian Department of the Academy of Sciences of the USSR (AN-SSSR) .
In 1938 Rotinjan was arrested by the NKVD for participating in the counterrevolutionary organization of the Armenian Revolutionary Federation . His closest friend LA Orbeli applied for Rotinjan rehabilitation at the request of Rotinjan’s daughter Lusik . Rotinjan was released in 1946.
In 1946 Rotinjan became Professor of Inorganic Chemistry at the Agricultural Institute in Kirowabad , which later became the Azerbaijani University of Agricultural Sciences . In 1948 he moved to the Chuvash Agricultural Institute in Cheboksary .
In 1953 Rotinjan returned to Armenia at the Yerevan Polytechnic Institute. In 1955 he received his doctorate in chemical sciences without submitting a dissertation at the suggestion of the Institute for General and Inorganic Chemistry of the AN-SSSR . 1957-1960 he worked in the research facility of the People's Commissariat for Armenia.
Together with FE Dreyer, Rotinjan created the first textbook for an internship in physical chemistry in Russia . NS Jenikolopow was one of his students . With regard to the rocks in Armenia, Rotinjan and his colleagues investigated the melting and crystallization of rocks. With his work he contributed to the development and growth of the copper and cement industry in Armenia.
Rotinyan's son Alexander Leonowitsch became an electrochemist.
