    Abstract: The free fatty acid remaining in a reaction product obtained by esterification of a propoxylated glycerin with excess fatty acid may be reduced to low levels by treating the reaction product with a solid basic compound, preferably one having a small particle size and high surface area, and then filtering. The purified composition thus obtained contains little or no residual basic compound and is suitable for use as a reduced calorie fat substitute in the preparation of food products.

    Abstract: Substances useful as water reducing and superplasticizer additives for cement compositions are formed by reaction of carboxylic acid polymers with a polyether, preferably a mixture of monofunctional and difunctional polyethers, derived from C2-C4 epoxides wherein partial cleavage of the polyethers and esterification of the polyethers and the cleavage products thereof by the other reactant are achieved. In one embodiment, a sulfonic acid is used to catalyze the reaction of poly(acrylic acid), a monofunctional ethylene oxide-propylene oxide copolymer, and a difunctional poly(propylene glycol), at a temperature in excess of 140 DEG C.

    Abstract: Double metal cyanide (DMC) catalysts useful for epoxide polymerizations are disclosed. The catalysts comprise a DMC compound, an organic complexing agent, and from about 2 to about 80 wt.% of a functionalized polymer or a water-soluble salt derived from the polymer. The catalysts are easy to prepare and isolate, are substantially non-crystalline, and have high activity for polymerizing epoxides. Polyols made from the catalysts have exceptionally low unsaturations, low viscosities, and reduced levels of high molecular weight polyol tail.
