Abstract
PURPOSE: To obtain an alkylene glycol diether, by the reaction of an ethereal compound having a lower alkyl group with an alkylene oxide in the presence of BF3, etc. and a compound having an active hydrogen atom to introduce the alkylene oxide directly into the chain ether.
CONSTITUTION: The aimed compound is obtained by the reaction of preferably an ethereal compound having a lower alkyl group of formula I (R1 is lower alkyl; R2 is 1W12C alkyl, phenyl substituted with lower alkyl, etc. or aralkyl etc.; m is an integer 1W4; n is an integer 0W8) etc. with preferably an alkylene oxide of formula II (R3 is a halogen substituted or unsubstituted 1W5C alkyl or phenyl), formula III (l is an integer 0W5), etc. at 20W80°C in the presence of BF3 or/and SnCl4 and a compound having an active hydrogen atom. Water, alcohols, carboxylic acids, phenols, etc. may be used as the compound having an active hydrogen atom.
