Abstract
A process to form glycol ethers by reacting an organic compound (A) having at least one aliphatic hydroxyl group with an oxirane compound (B) under reaction conditions in the presence of a catalytic amount of a polymeric material that is substantially insoluble in the reaction mixture, said polymeric material having a plurality of pendant sulfonate moieties with divalent metal counterions. Preferential formation of the mono adduct of glycol ethers is noted.
Claims19
A process comprising reacting an organic compound (A) having at least one aliphatic hydroxyl group with an oxirane compound (B) under reaction conditions to form a glycol ether, said process occurring in the presence of a catalytic amount of a polymeric material that is substantially insoluble in the reaction mixture, said polymeric material being selected from the group consisting of sulfonated styrene-divinylbenzene copolymers, sulfonated polyethylene resins, and perfluorosulfonic acid polymers having a plurality of pendant sulfonate moieties with divalent metal counterions selected from the group of 2a, 2b and 8 elements of the Periodic Table.
A process as defined in claim 1, 4, 9, 11 or 14 wherein said polymeric material is a styrene-divinylbenzene copolymer resin.
