Abstract:

The reaction of Na stearate [822-16-2] with epichlorohydrin [106-89-8] in the presence of phase-transfer catalysts (tetraalkylammonium halides) gave 90% glycerol monostearate [31566-31-1] with purity 97%. The effect of reactant ratio, catalyst type and concn., and temp. were studied. An efficient, economical process was developed, including recycle of solvent and excess epichlorohydrin and recovery of 80% catalyst. The monoglycerides so prepd. are not food grade, but com. monoglycerides can be prepd. [on SciFinder(R)]
