摘要： Reduced calorie food compositions are prepared using fatty acid esterified alkoxylated polyol fat substitutes derived from C.sub.3 and higher epoxides and having a high proportion of primary ester linkages. The fat substitutes may be obtained by alkoxylation of a polyol such as glycerin with the epoxide in the presence of a cationic/ring-opening polymerization catalyst, followed by esterification with a fatty acid or a fatty acid equivalent.

摘要： A process for purifying allyl acetate is disclosed. An acetoxylation mixture is distilled at elevated pressure to remove propylene and generate a first bottoms mixture comprising allyl acetate, acetic acid, acrolein, allyl diacetate, and 3-acetoxypropionaldehyde. The first bottoms mixture is flash vaporized, and the resulting vapor is contacted with a solid acidic catalyst under conditions effective to decompose allyl diacetate and 3-acetoxypropionaldehyde. The flashed product, which comprises allyl acetate, acetic acid, and acrolein, is then distilled to remove acrolein and generate a second bottoms mixture comprising allyl acetate and acetic acid. The second bottoms mixture can be used to manufacture allyl alcohol.

摘要： An acrylic emulsion is disclosed. The emulsion comprises from about 30% to about 90% by weight of water, about 10% to about 70% by weight of an acrylic polymer, about 0.2% to about 10% by weight of a emulsifying agent, and up to 20% by weight of an organic solvent. The acrylic polymer contains from about 20% to about 80% by weight of recurring units of t-butyl acrylate or methacrylate. Latex coatings formulated from the acrylic emulsion show significantly improved resistance to moisture and corrosion.

摘要： A process for making and purifying dipropylene glycol tert-butyl ethers (DPTB). DPTB is made by reacting dipropylene glycol with isobutylene in the presence of an acidic catalyst. Extractive distillation of the product mixture using a glycol extracting agent, preferably dipropylene glycol, allows removal of di-tert-butyl ether impurities as an overhead product. The DPTB product is then distilled to separate it from the glycol extracting agent. High-purity DPTB, substantially free of diethers and exceptionally useful as a solvent, is obtained from the process.

摘要： Versatile coalescing agents for water-borne coating applications are disclosed. The coalescents comprise propoxylated propylene glycol tert-butyl ether and one or more organic solvents, particularly glycol ethers.
