Abstract

FIELD: production of benzine component. SUBSTANCE: desired component represents mixture of C-Calkyl-tert-C-Calkyl ethers and corresponding tertiary C-Calcohols. Said mixture is prepared by etherification of tertiary C-Colefins by aliphatic C-Calcohols simultaneously with their hydration by water. The process takes place in liquid phase in the presence of acid catalyst (e. g. sulfuric acid). Thus prepared reaction mixture is separated into catalyst phase and hydrocarbon phase. The latter is washed by water, washing water is fed into reaction zone, and washed hydrocarbon phase is affected by rectification. Desired product which contains ethers (their quantity being 10-90 mass %) is separated during said rectification. Conversion of olefins is 70-98 %. Desired product contains C-Calcohol (its quantity being 0.01-0.06 %), dimmers, polymers of olefins (their quantity being 0.01-0.03 %) and water (its quantity being 0.007-0.009 %). EFFECT: improves efficiency of the method.

Изобретение относится к усовершенствованному способу получения высокооктанового компонента бензина, представляющего собой смесь С1-С4 аклил-трет-С4-С5 алкиловых простых эфиров (далее простые эфиры) и соответствующих С4-С5 третичных спиртов (далее - третичные спирты). Указанную смесь простых эфиров и третичных спиртов получают одновременным проведением этерификации третичных олефинов С4-С5 алифатическими спиртами С1-С4 и гидратации их водой в жидкой фазе в присутствии гомогенного кислотного катализатора, например серной кислоты, разделением реакционной массы на катализаторную фазу, которую рециркулируют в реакционную зону, и углеводородную фазу, которую промывают водой и промывную воду подают в реакционную зону, а из промытой углеводородной фазы ректификацией выделяют целевой продукт состава 10-90 мас. %, простых эфиров 10-90% соответствующих третичных спиртов. Конверсия олефина 70-98%. Содержание спирта С1-С4 в целевом продукте 0,01-0,06%, димеров, полимеров олефинов 0,01-0,03%, воды 0,007-0,009%The invention relates to an improved method for producing a high-octane gasoline component, which is a mixture of C 1 -C 4 acyl-tert-C 4 -C 5 alkyl ethers (hereinafter ethers) and the corresponding C 4 -C 5 tertiary alcohols (hereinafter referred to as tertiary alcohols) . The specified mixture of ethers and tertiary alcohols is obtained by simultaneously esterifying C 4 -C 5 tertiary olefins with C 1 -C 4 aliphatic alcohols and hydrating them with water in the liquid phase in the presence of a homogeneous acid catalyst, for example sulfuric acid, by separating the reaction mass into the catalyst phase, which recycle to the reaction zone, and the hydrocarbon phase, which is washed with water and the wash water, is supplied to the reaction zone, and the target product of composition 10-9 is isolated from the washed hydrocarbon phase by rectification. 0 wt. % ethers 10-90% of the corresponding tertiary alcohols. Olefin conversion 70-98%. The alcohol content of C 1 -C 4 in the target product is 0.01-0.06%, dimers, polymers of olefins 0.01-0.03%, water 0.007-0.009%
