Abstract

1. Способ предотвращения термополимеризации диеновых углеводородов в процессе их выделения экстрактивной ректификацией путем введения в количестве 0,05-0,25% от массы диенового углеводорода ингибитора термополимеризации, содержащего нитрит натрия, отличающийся тем, что, с целью удешевления процесса и уменьшения забивки оборудования термополимером, используют ингибитор, дополнительно содержащий смесь фенолов, выделяемую из сточных вод процесса полукоксования углей, при весовом соотношении нитрит натрия: смесь фенолов, равном 1-2:1-6.2. Способ по п. 1, отличающийся тем, что процесс проводят при весовом соотношении нитрит натрия:смесь фенолов, равном 1-2:1.1. The way to prevent thermopolymerization of diene hydrocarbons in the process of their extraction with extractive distillation by introducing in an amount of 0.05-0.25% by weight of the diene hydrocarbon a thermopolymerization inhibitor containing sodium nitrite, characterized in that, in order to reduce the cost of the process and reduce the driving of equipment by thermopolymer , an inhibitor is used, which additionally contains a mixture of phenols emitted from the sewage of the semi-coking process of coal, with a weight ratio of sodium nitrite: a mixture of phenols equal to 1-2: 1-6.2. The method according to p. 1, characterized in that the process is carried out at a weight ratio of sodium nitrite: a mixture of phenols, equal to 1-2: 1.
