Pavlov, S. Karsakov, S. Pavlov] Physicochemical substantiation and improved more effective technologies for C4-hydrocarbons separation and 1,3-butadiene purification with the help of polar extragents are given, such as compressorless extractive rectification with the use of an intermediate desorbent, extractive rectification of the butane-n-butene fraction with preliminary isomerization of 1-butene into 2-butenes, the combined removal of -acetylenes C4 and methylallene by rectification with a small introduction of the extragent, and the hydration of butenyne in the C4 fraction and distillation of propyne from it.
