Benzoic Acid → Benzoyl chloride

Participants

Reaction Steps

Shaking once with 300 ml of methylene chloride completely removes small quanitites of benzoic acid formed by the hydrolysis of adhering benzoyl chloride. The hydrolysis solution is neutralized with sodium hydroxide and made up with water to 750 ml. The 1,3-dimethyl-1-oxophospholine is isolated from the neutral solution in the same way as in Example 1. Yield: 109 g of 1,3-dimethyl-1-oxophospholine (41.9% of the theoretical yield).
