    摘要: 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.

    摘要: The specification describes a process for the production of a 4-alkoxymethyl-1,3-dioxolan in good yield, in high purity and in a simple manner by reacting an alkyl glycidyl ether with a carbonyl compound in the presence of an acid catalyst. The 4-alkoxymethyl-1,3-dioxolan is useful as an intermediate for the production of an .alpha.-monoalkyl glyceryl ether by hydrolysis.
