TREATMENT OF NITRILES WITH GLYCOLIC ACID |
摘要 |
A process for purifyiing a nitrile such as acrylonitrile is disclosed. The process comprises (1) contacting a product mixture, which comprises acrylonitrile and hydrogen cyanide, with glycolic acid or a glycolic acid-generating compound to produce a glycolic acid-treated product; and (2) recovering the nitrile from the glycolic acid-treated product. The product mixture can be produced by contacting ammonia with an olefin under a condition effective to produce a nitrile and hydrogen cyanide.
