Description
Известен способ получени моющих веществ путем обработки олефинов серной кислотой и последующего отделени раствора образовавшихс сульфоэфиров от отработанной серной кислоты.A method of producing detergents is known by treating olefins with sulfuric acid and then separating the solution of the resulting sulfoesters from the spent sulfuric acid.
Описываемый способ, по сравнению с известным, вл етс более экономичным. С этой целью отделение отработанной кислоты производ т путем охлаждени реакционной массы до температуры ниже плюс 5° и последующего отстаивани ее или центрифугировани .The described method, in comparison with the known, is more economical. To this end, the spent acid is separated by cooling the reaction mass to a temperature below + 5 ° C and then settling it or centrifuging.
Поскольку сырье дл получени моющих веществ состоит из смеси олефинов с предельными парафиновыми углеводородами, способствующими отделению кислых сульфоэфиров от серной кислоты, то избыток последней до ее нейтрализации щелочью отстаивают в сосудах, охлаждаемых до плюс 5° или минус 10°, или центрифугируют.Since the raw materials for the preparation of detergents consist of a mixture of olefins with paraffin-saturated paraffinic hydrocarbons, which promote the separation of acidic sulfo-ethers from sulfuric acid, the excess of the latter is neutralized in vessels cooled to plus 5 ° or minus 10 ° before being neutralized by alkali.
В отдел емом при охлаждении сернокислотном слое остаетс около 1 %алкилсульфоэфиров и около 1% углеводородов. Содержание серной кислоты в сернокислотном слое, котора может быть возвращена в цикл обработки олефинов, составл ет 95-98%.About 1% of alkyl sulfoethers and about 1% of hydrocarbons remain in the sulfuric acid layer separated during cooling. The content of sulfuric acid in the sulfuric acid layer, which can be returned to the olefin processing cycle, is 95-98%.
Предмет изобретени Subject invention
Способ получени моющих веществ путем обработки олефинов серной кислотой и последующего отделени раствора образовавщихс сульфоэфиров от отработанной серной кислоты, отличающийс тем, что, с целью удешевлени процесса, отделение отработанной кислоты производ т путем охлаждени реакционной массы до температуры ниже плюс 5°и последующего отстаивани ее или центрифугировани .The method of obtaining detergents by treating olefins with sulfuric acid and then separating the solution of the resulting sulfoesters from the spent sulfuric acid, characterized in that, in order to reduce the cost of the process, the separation of the spent acid is carried out by cooling the reaction mass to below + 5 ° C and then settling it or centrifugation.
