ABSTRACT:
A process is provided for separating gaseous phosphorus trichloride from a gas stream. The process comprises contacting the gas stream with a condensing amount of liquid phosphorus trichloride to c ondense a portion of the gaseous phosphorus trichloride to liquid phosphorus trichloride. The liquid phsphorus trichloride is then separated from the gas stream. A process apparatus is also provided. The process is particularly useful in preventing or reducing the discharge of gaseous phosphorus trichloride to the atmosphere due to the accidental discharge of a high volume gas stream from a phosphorus trichloride reaction vessel.
