ABSTRACT:
The yield and purity of 2-halomethyl-1,3-cyclic acetals is improved by subjecting the reaction product of 1,2-dihaloethyl acetate and aliphatic diol to alkaline hydrolysis. The resulting aqueous and organic phases are separated and the organic phase distilled to recover the 2-halomethyl-1,3-cyclic acetal product.
