Abstract
Inventia se refera la un procedeu pentru prepararea anhidridei acidului izobutiric, conform caruia propena este carbonilata într-un exces de acid fluorhidric cu formarea fluorurii de izobutiril, apoi amestecul de reactie de la carbonilare este fractionat, fluorura de izobutiroil formata este hidrolizata partial la o temperatura de la 0 la 100 degree C, în prezenta unui acceptor de acid care este o florura de metal alcalin si utilizînd 0,05 la 0,5 mol de apa la molde florura de izobutirol, apoi separînd fluorura de izobutiroil prin distilare fractionata si recirculînd-o în etapa de hidroliza si rezultînd o fractiune de produs, anhidrida a acidului fluorhidric-acceptor separat din amestecul de hidroliza si încalzit pentru a rezulta acid fluorhidric, care este recirculat si regenerînd acceptorul.
