Versuchsvorschrift

There were present in a stirring apparatus 577.5 grams of a 40% sodium trithiocarbonate solution (corresponding to 1.5 moles). Under stirring at -10° C. there were dropped in 128 grams of isobutyl acrylate (1.0 mole). Post stirring was continued for a further 10 minutes and then the mixture was acidified with 350 ml of 32% hydrochloric acid. After the phase separation the organic phase was fractionally distilled. There were obtained 128 grams of mercaptopropionic acid isobutyl ester (corresponding to a yield of 79%).
