Reaction Conditions

Reaction Steps

In a dry 2-necked, round bottomed flask, equipped with a magnetic stirrer and fixed with a separatory funnel, containing 4.81 ml (66 mmol) of thionyl chloride, and a water condenser, is placed 15.65 g (55 mmol) of stearic acid. Addition of the thionyl chloride is completed with heating to about 45° C. over the course of about 40 minutes. When addition of the thionyl chloride is complete the mixture is heated and stirred for an additional 45 minutes. The water condenser is then replaced with a distillation side arm condenser and the crude mixture is distilled. The crude distillate in the receiving flask is then fractionally distilled to obtain the acyl chloride, stearoyl chloride.
