Abstract

Способ очистки изопентана, используемого в качестве растворителя в процессе полимеризации изопрена, путем азеотропной осушки с выделением в качестве кубового остатка целевого продукта и азеотропа, углеводородную часть которого направляют на ректификацию, с выделением в качестве дистиллата смеси углеводородов Cи Cи кубового продукта, рециркулируемого в виде флегмы на азеотропную осушку, отличающийся тем, что, с целью повышения степени очистки, в качестве дистиллата при ректификации отбирают смесь углеводородов Cи Cв весовом соотношении 1 : 0,5 - 1,5 и рециркуляцию кубового продукта проводят при весовом соотношении флегма : исходное сырье 1 : 1 - 5..The method of purification of isopentane, used as a solvent in the process of polymerization of isoprene, by azeotropic drying with separation of the desired product as a bottoms residue and azeotrope, the hydrocarbon portion of which is sent for rectification, with a mixture of hydrocarbons of Ci and Cubic products recycled as reflux as distillate for azeotropic drying, characterized in that, in order to increase the degree of purification, a mixture of hydrocarbons Ci Cv is taken as a distillate during rectification in a weight ratio 1: 0.5 to 1.5 and the recycling of the cubic product is carried out at a weight ratio of reflux: feedstock 1: 1 - 5 ..
