Use | for organic synthesis. used as intermediate in organic synthesis |
production method | is obtained by reacting propionic acid with sulfuryl chloride and thionyl chloride. 59.2G of propionic acid, 54.0G of sulfuryl chloride and 61.6g of carbon tetrachloride were mixed, and 0.5g of benzoyl peroxide was added. Reflux was protected from light for 1.5h until there was no further gas evolution. Additional excess thionyl chloride 190.4g was added and refluxed for 4H. The solvent is then evaporated off at atmospheric pressure and the excess of thionyl chloride and propionyl chloride. The remainder was fractionated under reduced pressure, and 2-chloropropionyl chloride was collected as the 51-54 ℃(13.3kPa) fraction, and 3-chloropropionyl chloride was collected as the 81-84 ℃(13.3kPa) fraction, which accounted for 45% and 55%, respectively, the overall yield was 75%. |
