Process for the production of glyceryl ethers

Claim 1

A process for the production of an α-monoalkylglyceryl ether represented by the formula (III): ##STR18## where R is a saturated or unsaturated, straight chain or branched chain aliphatic hydrocarbyl group having from 8 to 24 carbon atoms, which process is characterized in that an alkyl glycidyl ether represented by the formula (I): ##STR19## where R is as defined above and a carbonyl compound of formula R 1 COR 2 wherein R 1 is a hydrogen atom or hydrocarbyl group and R 2 is a hydrocarbyl group respectively are reacted in the presence of a Lewis acid catalyst, to obtain a 4-alkoxymethyl-1,3-dioxolan represented by the formula (II): ##STR20## where R is as defined above, R 1 and R 2 are as defined above, and said alkoxymethyl-1,3-dioxolan is then hydrolyzed to said α-monoalkyl-glyceryl ether, said alkyl glycidyl ether and the carbonyl compound being reacted in a molar ratio of 1:1-30, the Lewis acid catalyst being employed in an amount of 0.001-0.2 mole per mole of alkyl glycidyl ether, and the reaction temperature being 0°-70° C.
