What are the impurities present in the acrylonitrile column in the man

1.	What are the impurities present in the acrylonitrile column in the manufacture of acrylonitrile from propylene-ammonia-air oxidation process?(a) Saturated alcohol(b) Saturated carboxylic isocyanide(c) Saturated carboxylic cyanohydrin(d) Dust particlesI had been asked this question in a job interview.My question comes from C3 Compounds in division Synthetic Organic Chemical Industries of Chemical Technology
Answer» Correct choice is (c) Saturated carboxylic cyanohydrin To explain I would say: Impurities in the final ACRYLONITRILE COLUMN which give TROUBLE are saturated carboxylic cyanohydrins (HO-R-CN). These dissociate to form VOLATILE contaminants.
