Reaction Steps
226 g (1 mol) of 2,4,4,4-tetrachlorobutyric acid [produced according to CA, 63, 13089e (1965)], 600 g of thionyl chloride and 1 ml of N,N-dimethylformamide are heated for 2 hours at 50° C. and for 2 hours at 75° C. After the unreacted thionyl chloride has been evaporated off, the residue is distilled to obtain 227.6 g (93% of theory) of 2,4,4,4-tetrachlorobutyric acid chloride; b.p. 90°-91° C./15 mm Hg.
