    摘要： The phase separation in the decanter of a process for producing acetic acid by carbonylating methanol in the presence of a catalyst under low water-high acid conditions is improved by forming a liquid mixture (D) which has a water content of at most 20% by weight, based on the weight of the liquid mixture, and a weight ratio of acetic acid to water of at least 1:1, and partitioning the liquid mixture by providing for an alkane(s) content of D of from 0.1 to 15% by weight, based on the weight of D, to obtain a light, aqueous phase and a heavy, organic phase.

    摘要： A catalyst, useful for the direct epoxidation of olefins, is disclosed. The catalyst comprises palladium nanoparticles, support nanoparticles, and a titanium zeolite having a particle size of 2 microns or greater. The palladium nanoparticles are deposited on the support nanoparticles to form supported palladium nanoparticles, and the supported palladium nanoparticles are deposited on the titanium zeolite; or the supported palladium nanoparticles are deposited on a carrier having a particle size of 2 microns or greater. The invention also includes a process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in the presence of the catalyst. The catalysts are more active in epoxidation reactions, while demonstrating the same or better selectivity.

    摘要： This invention is a process for producing propylene oxide. The process comprises first contacting a titanium zeolite with a reaction feed comprising propylene, hydrogen peroxide, tertiary butyl alcohol, and water to produce a product stream comprising propylene, propylene oxide, propylene glycol, tertiary butyl alcohol, and water. The product stream is distilled to produce a first overhead stream comprising propylene and a first bottoms stream comprising propylene oxide, propylene glycol, tertiary butyl alcohol, and water. The first bottoms stream is distilled to produce a second overhead stream comprising propylene oxide and a second bottoms product stream comprising propylene glycol, tertiary butyl alcohol, and water. The second bottoms stream is distilled to produce a third overhead stream comprising an azeotrope of tertiary butyl alcohol and water and a third bottoms stream comprising propylene glycol and water.
