Abstract: A process for producing acetonitrile, the process comprising: treating a feedstock stream comprising methanol, allyl alcohol, oxazole, acetonitrile, water, and hydrogen cyanide to remove hydrogen cyanide and produce an acetonitrile stream comprising less than 1 wt.% hydrogen cyanide. The process further comprises the step of distilling the acetonitrile stream in a first distillation column to produce a first distillate comprising oxazole and methanol; a first intermediate acetonitrile stream comprising acetonitrile and oxazole and less than 1 wt% allyl alcohol; a first bottoms stream comprising allyl alcohol and water. The process further comprises the step of purifying the first intermediate acetonitrile stream to produce an acetonitrile product stream and a recycle stream comprising allyl alcohol.
