METHOD FOR ISOLATION OF TERTIARY OLEFINS Russian patent published in 1994 - IPC

Abstract RU 2005710 C1

FIELD: production processes. SUBSTANCE: mixture of hydrocarbons of various nonsaturation degrees are brought in contact with alcohol C1-C4 in presence of ionite formed catalyst in reaction-rectifying apparatus, with alcohol delivered in the amount ensuring its content of 10-85% in still product. Then produced ether contained in still product and mixed with alcohol is decomposed in another reaction-rectifying apparatus in presence of the same catalyst. This other apparatus has a reaction zone filled with catalyst, and upper and lower rectifying zones. Still product is delivered from first apparatus at 100-175 C into upper rectifying zone of second apparatus, on 5-10th plate above layer of catalyst. EFFECT: higher degree of extraction of tertiary olefins, lower energy expenditures, and simpler technology.
