Preparation of butyryl chloride

To a round bottom flask fitted with a funnel 38 grams of oxalyl chloride are placed. 20 g of dry butyric acid were added slowly to the oxalyl chloride from a funnel. Soon the odor peculiar to all acid chlorides were perceptible, while the ester odor of butyric anhydride was entirely absent. 15 g of the acid chloride was obtained with boiling point 99-101°. According to literature  100-101.5°. The yield was 63%.
