    摘要: The present invention provides a coalescing agent for aqueous coatings, a coalescing agent composition, and an aqueous coating. The coalescing agent for aqueous coatings is obtained by esterification reaction of fatty acids and glycol ethers. The coalescing agent prepared by the present invention has a boiling point as high as 330° C., has no irritant odor, and is environmental friendly and safe. It overcomes shortcomings of conventional coalescing agents, which is suitable for various polymer emulsion systems, and can significantly reduce the film-forming temperature of aqueous emulsion coatings and optimize the film-forming performance.

    摘要: A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.
