METHOD OF SEPARATING ACRYLONITRILE |
摘要 |
Acrylonitrile or methacrylonitrile found in the reactor effluent of the ammoxidation reaction of propylene or isobutylene is recovered by cooling the reactor effluent to a temperature of about 40 DEG to about 100 DEG C. using direct contacting cooling, preferably with an aqueous stream, to obtain a gaseous stream containing acrylonitrile or methacrylonitrile and cooling the gaseous stream using indirect contact cooling to condense at least some of the acrylonitrile or methacrylonitrile from the gaseous stream. |
