METHOD OF COMBINED SYNTHESIS OF DI-N-BUTENE AND ALKYL-TERTIARY- BUTYL ESTERS FROM NATURAL BUTANES |
摘要 |
organic chemistry, hydrocarbons, chemical technology. SUBSTANCE: natural butanes are separated for n-butane and isobutane and n-butane is subjected for dehydrogenation with the following oligoisomerization of synthesized n-butene to a mixture of oligomers and isolation of di-n-butene from the latter. Isobutane is subjected for dehydrogenation to mixture containing isobutene that is subjected for interaction with alkanol to alkyl-tert. -butyl ester at the stage of esterification. EFFECT: enhanced economy of process. 7 cl, 1 dwg |
