Abstract

Способ выделения изопрена из смеси углеводородов Сразной степени насыщенности путем экстрактивной ректификации селективным растворителем с получением в виде дистиллята изопрена и в виде кубового продукта насыщенного селективного растворителя, который подвергают десорбции в колонне при повышенной температуре куба колонны с выделением в виде кубового продукта селективного растворителя, рециркулируемого на экстрактивную ректификацию, отличающийся тем, что, с целью повышения степени очистки изопрена, десорбцию проводят при температуре куба колонны, равной 160 - 250C.The method of separation of isoprene from hydrocarbon mixture extractive distillation, characterized in that, in order to increase the degree of purification of isoprene, desorption is carried out at re cube column, equal to 160 - 250C.
