Abstract

Метод за получаване на третични бутилалкилетери от с долу 4-въглеродна суровина, съдържаща понякога с долу 3 и с долу 5 компоненти, от която предварително се отделя бутадиенът, чрез подаване на с долу 4-суровина, пречистена напълно или със следи от бутадиен, към секция за синтез, запълнена с катализатор, представляващ кисела йонообменна смола, по-специално сулфониран съполимер на стирол с дивинилбензол, в която секция изобутенът, съдържащ се в с долу 4-въглеводородната фрак ция, взаимодействува с алифатен алкохол до получаване на третичен бутилалкилетер, който се отделя от останалите с долу 4-въглеводороди, характеризиращ се с това, че останалите с долу 4-въглеводороди се подлагат на фракциониране в два или три стадия, при които се отделят наситените въглеводороди от бутен-1 и бутен-2, и бутен-1 и/или бутен-2 се подлагат на изомеризация, където частично се превръщат в изобутен и се получава една въглеводородна фракция, съдържаща предимно бутен1, бутен-2 и изобутен заедно с тежки продукти и наситени компоненти, която се подава към секцията за синтез на третичен бутилалкилетер. Патентните претенции са формулирани в 4 точки.Method for obtaining tertiary butyl alkyl ethers from a lower 4-carbon raw material, sometimes containing lower 3 and lower 5 components, from which the butadiene is previously separated, by feeding lower 4-raw material, completely purified or with traces of butadiene, to a synthesis section filled with a catalyst representing an acidic ion exchange resin, in particular a sulfonated copolymer of styrene with divinylbenzene, in which section the isobutene contained in the lower 4-hydrocarbon fraction reacts with an aliphatic alcohol to produce a tertiary butyl alkyl ether which is separated from the remaining lower 4-hydrocarbons, characterized in that the remaining lower 4-hydrocarbons are subjected to fractionation in two or three stages, in which the saturated hydrocarbons of butene-1 and butene-2, and butene- 1 and/or butene-2 are subjected to isomerization, where they are partially converted to isobutene and a hydrocarbon fraction containing mainly butene-1, butene-2 and isobutene together with heavy products and saturated components is obtained, which is fed to the synthesis section tertiary butyl alkyl ether. The patent claims are formulated in 4 points.
