Abstract
Some 4-(2'-hydroxy-3'-alkoxy)propoxymethyl-1,3-dioxolanes are prepared by reacting alkylglycidyl ethers with acetal or ketal derivatives of glycerol in the presence of an acidic or basic catalyst. Also disclosed is a process for preparing certain 2-hydroxy-3-alkoxy-propylglyceryl ethers, which process comprises subjecting the 4-(2'-hydroxy-3'-alkoxy)propoxymethyl-1,3-dioxolanes to hydrolysis. The above processes can afford intended reaction products with good yield without need for any special post-reaction treatment.
