1 mole of the monothioglycerol ether obtained in Example 1 is diluted with 110 g of acetic anhydride. While cooling with ice water, 15 ml of conc. sulfuric acid are added dropwise to this solution. The temperature should not exceed 40° C. The batch is stirred for 1 hour, diluted with water, and then extracted with ether. The ethereal extract is washed neutral with sodium bicarbonate solution. Distillation at 85° C./4.10-3 torr yields 3-(2-ethylhexyloxy)-2-acetoxy-1-propanethiol as an odourless oil with a SH content of 11.6%.
