GASOLINES

GASOLINES, mixture of hydrocarbons of different chemical formulas. First pro­ duction of the straight­run G. (A­66) in 1936 was mastered in Bashkortostan at the Ishimbay Oil Refinery, in 1938 – at the Ufa Cracking Plant. High­octane unleaded G. of AI­91 grades have been produced since 1997 (Novo­Ufimsky Refinery); using methyl t­butyl ether as an oxygen­containing ad­ ditive at the Ufa Oil Refinery – G. AI­92, AI­95.  Gazprom  Neftekhim  Salavat produces unleaded G. A­76, AI­91, AI­93, AI­95. The RB enterprises produces 4 grades of G. of Standard 1999: normal­80 (conforms to A­76 grade of Standard 1977), regular­91 (AI­91), premium­95 (AI­95), super­98 (AI­98), unleaded AI­92 for domestically manufac­ tured trucks and passenger vehicles; jet fuels B­70, B­89, B­92, B­95/115, B­95/130, B­100/130; G.­solvents (Galosha, White Spirit). Approx. 30% of the total G. output in RF is produced by the RB enterprises; they are the leaders in the production of motor G. (11.8%), which are similar in terms of composition and quality indices, to foreign analogues (2017).
