Abstract
Przedmiotem wynalazku jest sposób regeneracji rozpuszczalnika stosowanego w destylacji ekstrakcyjnej mieszanin węglowodorów nienasyconych C4, korzystnie rozpuszczalnika polarnego z grupy obejmującej DMF, ACN, NMP, DMSO, zawierającego nienasycone węglowodory acetylenowe i dienowe, w szczególności metyloacetylen, etyloacetylen, winyloacetylen, 1,2-butadien, propadien, ewentualnie 1,3-butadien, izomery butenu, dimery i inne węglowodory ciężkie C5+, który polega na tym, że przed regeneracją rozpuszczalnika za pomocą destylacji poddaje się go uwodornieniu.
