Abstract
Procedeul integrat de obtinere a eterilor tert-butilalchilici si a 1-butenei, conform inventiei, consta în aceea ca, dupa separarea eterului tert-butilalchilic, rezidul de reactie se supune unei distilari extractive folosind ca solvent de extractie acetonitrilul, separîndu-se ca produs de vîrf hidrocarburile saturate C4 si hidrocarburile C3 iar ca produs de blaz 1-butena, 2-butena, ceea ce ramîne în hidrocarburile grele C5, produsul de blaz fiind apoi stripat pentru separarea solventului care se recircula, dupa care distileaza separîndu-se o fractie de vîrf ce contine butena-1 si o fractie de blaz care se izomerizeaza în scopul transformarii butenii-2 si restului de butena-1 în izobutena, aceasta fractie izomerizata fiind apoi recirculata la zona de sinteza a eterului tert-butilalchilic.
