POLYGLYCEROL MONOETHERS AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A polyglycerol monoether is represented by following General Formula (1):
€€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒRO- (C 3 H 6 O 2 ) n -H€ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein R represents an alcohol residue having one to thirty carbon atoms; and "n" is an average number of moles of added glycerol units and represents a number of 2 or more, and has a content (peak area percentage) of monoether components of 75% or more and a content (peak area percentage) of diether components of 5% or less, as determined by reversed-phase partition high-performance liquid chromatography using a 80:20 (by volume) mixture of methanol and water as an eluent. The polyglycerol monoether may be prepared by adding a basic substance to an alcohol to yield an alkoxide, adding glycidol to the alkoxide, and subjecting them to a reaction at 0
C to 100
