Reaction Steps

In a similar manner to the preceding Examples, 92.5 g (1 mol) of chloroacetone and 110.5 g (1 mol) of 3-chloro-1,2-propanediol are boiled together in a water separator with 0.5 g of p-TSA and 150 ml of cyclohexane. Once the equivalent quantity of water has separated, the cyclohexane is removed and the residue fractionated. 162 g (87%) of 2,4-bis(chloromethyl)-2-methyl-1,3-dioxolane are obtained. Bp.: 98° C. to 102° C. (1500 Pa); IR: acetal bands at 1120 cm−1, 1098 cm−1, 1053 cm−1, MS: m/e=169 (M−15), 135, 106, 93, 75, 57, 49, 43.
