Abstract

Способ предотвращения термополимеризации бутадиена в процессе его очистки от примесей ректификацией путем введения ингибитора на основе диамина, отличающийся тем, что, с целью снижения расхода ингибитора и потерь бутадиена, в качестве ингибитора используют смесь, содержащую в качестве диамина N-изопропил-N'-фенил-п-фенилендиамин или диметилпропандиамин и дополнительно содержащую аммиак или диметиламин и окись азота при массовом соотношении компонентов 1 - 5 : 1 - 20 : 1 - 2 соответственно.The method of preventing thermopolymerization of butadiene in the process of its purification from impurities by distillation by introducing a diamine-based inhibitor, characterized in that, in order to reduce inhibitor consumption and butadiene loss, a mixture containing N-isopropyl-N'-phenyl as a diamine is used as an inhibitor -p-phenylenediamine or dimethylpropane diamine and additionally containing ammonia or dimethylamine and nitric oxide with a mass ratio of components of 1 - 5: 1 - 20: 1 - 2, respectively.
