A process for the recovery of oxazole comprising contacting a mixture comprising oxazole and acetonitrile with an acid to form an acid salt of oxazole; separating acid salt of the oxazole from the mixture; and neutralizing the acid salt of oxazole separated from the mixture to release oxazole.

Process for the recovery of oxazole

A method of producing stabilized crude acetonitrile (i.e. acetonitrile which has been treated to substantially eliminate polymerization of the acetonitrile upon vaporization) which comprises mixing crude acetonitrile, a strong base and aldehyde together, heating to the reflux temperature of the mixture to stabilize the crude acetonitrile and recovering the stabilize acetonitrile. This stabilized acetonitrile is utilized to manufacture hydrogen cyanide.

Method for stabilization of crude acetonitrile as oxidation or

A process of producing hydrogen cyanide from crude acetonitrile comprising contacting the crude acetonitrile with an ammoxidation catalyst at an elevated temperature in the presence of an oxygen containing gas and ammonia. Preferably, the process is performed in the absence of propylene.
