WebSep 1, 1971 · Phosgene is poorly absorbed when the gas in air is passed at a moderate rate through water or neutral buffer in a simple bubbler. Absorption is unchanged in acid solution but increased in alkaline, and increased still more in solutions containing non-ionized amines, phenoxide ions or sulphite. Web9. If excess oxalyl chloride (and/or phosgene) is not removed, the vigorous reaction with water during decomposition of the aluminum chloride complex contributes to hydrolysis of the product acid chloride by increasing the time needed to complete this step. The more dilute solution achieved by additional solvent helps to prevent this hydrolysis ...
