Use of tri:alkanolamine polyether(s) as demulsifiers in o/w emulsions - obtainable by condensing tri:alkanol:amine(s) in presence of (hypo)phosphorous acid

摘要

Trialkanolamine polyethers, obtainable by condensing tri-alkanolamine(s) in the presence of (hypo)phosphorus acid, are useful as demulsifiers in 0/W emulsion. The trialkanolamines are of formula (I), where R1-R3 = 1,2-(2-4C)alkylene.
