Triethylene glycol monobutyl ether Use and Manufacturing

Methods of Manufacturing

REACTION OF ETHYLENE OXIDE WITH ETHYL ALCOHOL (PRODUCT IS ISOLATED FROM THE RESULTANT MIXTURE OF ETHYL ETHERS OF GLYCOLS BY VACUUM DISTILLATION)|Ethylene glycol monoethers are commercially manufactured by reaction of an alcohol with ethylene oxide. /Ethylene Glycol Monoethers/|Ethylene glycol monoethers are usually produced by reaction of ethylene oxide with the appropriate alcohol. A mixture of homologues is obtained ... The glycol monoethers can be converted to diethers by alkylation with common alkylating agents, such as dimethyl sulfate or alkyl halides (Williamson synthesis). Glycol dimethyl ethers are formed by treatment of dimethyl ether with ethylene oxide. /Ethylene Glycol Monoethers/
