Ethyl oxalyl chloride Use and Manufacturing

Methods of Manufacturing

A mixture of potassium acetate (20 g), water (30 ml) and diethyl oxalate (29.2 g, 0.2 mol) was stirred at 70-80 °C for 2 h. The reaction mixture was cooled and condensed to 30 ml. After ethanol (50 ml) and diethyl ether (150 ml) were added, the solution was filtrated to give 23.61 g of potassium monoethyl oxalate (76percent). SOCl

Uses

For organic synthesis
