Ethylene glycol butylene glycol separation

2015-11-19View Original

Thread Content

:(Please explain how to separate ethylene glycol from 1,2-butanediol; the content of ethylene glycol is 45% and that of butanediol is 40%. It is sufficient if each component reaches a concentration of 90% after separation.) Could an expert give some guidance?
