Saint Petersburg State University Department Of Chemistry
The Faculty of Chemistry (since 2014 The Institute of Chemistry) at Saint Petersburg State University is one of the leading chemistry faculties in Russia. History Formally, the Department of Chemistry has been created as a separate entity of Saint Petersburg State University (then Leningrad State University) in 1929. However, the history of chemistry at Saint Petersburg State University began much earlier. First chemistry laboratory and lectures in chemistry were introduced at the University in 1833. One of the first professors of chemistry was Alexander Voskresensky, a doctoral student of Justus von Liebig. Voskresensky largely contributed to the growth of chemistry classes at the University. He initiated lectures in organic chemistry (1843) and promoted first scientific projects. Later, in 1868, the chemistry division hosted then by the Department of Physics and Mathematics was split into three to form the division of organic chemistry led by Aleksandr Butlerov, the division ...

Institute Of Chemisry
An institute is an organisational body created for a certain purpose. They are often research organisations (research institutes) created to do research on specific topics, or can also be a professional body. In some countries, institutes can be part of a university or other institutions of higher education, either as a group of departments or an autonomous educational institution without a traditional university status such as a "university institute" (see Institute of Technology). In some countries, such as South Korea and India, private schools are sometimes referred to as institutes, and in Spain, secondary schools are referred to as institutes. Historically, in some countries institutes were educational units imparting vocational training and often incorporating libraries, also known as mechanics' institutes. The word "institute" comes from a Latin word ''institutum'' meaning "facility" or "habit"; from ''instituere'' meaning "build", "create", "raise" or "educate". ...

Petergof
Petergof (russian: Петерго́ф), known as Petrodvorets () from 1944 to 1997, is a municipal town in Petrodvortsovy District of the federal city of St. Petersburg, located on the southern shore of the Gulf of Finland. The town hosts one of two campuses of Saint Petersburg State University and the Petrodvorets Watch Factory, one of the leading Russian watch manufactures.

Vasilievsky Island
Vasilyevsky Island (russian: Васи́льевский о́стров, Vasilyevsky Ostrov, V.O.) is an island in St. Petersburg, Russia, bordered by the Bolshaya Neva and Malaya Neva Rivers (in the delta of the Neva River) in the south and northeast, and by Neva Bay of the Gulf of Finland in the west. Vasilyevsky Island is separated from Dekabristov Island by the Smolenka River. Together they form the territory of Vasileostrovsky District, an administrative division of Saint Petersburg. Situated just across the river from the Winter Palace, it constitutes a large portion of the city's historic center. Two of the most famous St. Petersburg bridges, Palace Bridge and Blagoveshchensky Bridge, connect it with the mainland to the south. The Exchange Bridge and Tuchkov Bridge across the Malaya Neva connect it with Petrogradsky Island. Vasilyevsky Island is served by Vasileostrovskaya and Primorskaya stations of Saint Petersburg Metro ( Line 3 ). There are plans to build ...

Twelve Collegia
The Twelve Collegia, or Twelve Colleges (russian: Двeнaдцaть Коллегий), is the largest edifice from the Petrine era remaining in Saint Petersburg. It was designed by Domenico Trezzini and Theodor Schwertfeger and built from 1722 to 1744.300 years of Saint Petersburg: Swiss architecture on the NevaTwelve Colleges Pg. 1. Description The three story, red-brick complex of 12 buildings is 400–440 meters long, giving an illusion of one enormous edifice. The result is an "austerely structured" complex with a "rustic style". The original design separated the 12 individual buildings. In subsequent restructuring, they were connected to form the modern complex. History The Twelve Collegia was commissioned by Peter the Great, who wanted a place for the Russian government, at the time divided into 12 branches: * The Senate (created in February 1711, eventually renamed "Council of the Empire")Massie, Robert: ''Peter the Great: His Life and World.''

Tishchenko Reaction
The Tishchenko reaction is an organic chemical reaction that involves disproportionation of an aldehyde in the presence of an alkoxide. The reaction is named after Russian organic chemist Vyacheslav Tishchenko, who discovered that aluminium alkoxides are effective catalysts for the reaction. In the related Cannizzaro reaction, the base is sodium hydroxide and then the oxidation product is a carboxylic acid and the reduction product is an alcohol. History The reaction involving benzaldehyde was discovered by Claisen using sodium benzylate as base. The reaction produces benzyl benzoate. Enolizable aldehydes are not amenable to Claisen's conditions. Vyacheslav Tishchenko discovered that aluminium alkoxides allowed the conversion of enolizable aldehydes to esters. Examples * The Tishchenko reaction of acetaldehyde gives the commercially important solvent ethyl acetate. The reaction is catalyzed by aluminium alkoxides. * The Tishchenko reaction is used to obtain isobu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lev Aleksandrovich Chugaev
Lev Aleksandrovich Chugaev (16 October 1873 – 26 September 1922) was a Russian chemist. At the height of his career, he was professor of chemistry at the University of Petersburg, being the successor to Dmitri Mendeleev. He was active in the fields of inorganic chemistry, especially platinum group complexes, as well as organic chemistry. He is also known as Leo Aleksandrovich Tschugaeff or Tschugaev. Contributions to coordination chemistry Chugaev discovered that dimethylglyoxime forms a scarlet solid upon reaction with nickel(II) ions. This reaction was one of the first "spot tests" for a metal ion. An adherent to the theories of Alfred Werner, Chugaev made several contributions to the chemistry of platinum. The salt t(NH3)5Cll3 containing the chloropentammineplatinum(IV) ion, is called "Chugaev's salt".
