摘要:Process for the synthesis of polymers with laterally linked polyoxyalkylene chains by the free radical polymerization of polyoxyalkylene ethers with olefinic double bonds with other vinyl compounds, capable of copolymerizing wherein the polyoxyalkylene ethers of allyl and/or methallyl alcohol are copolymerized in a known manner with vinyl esters of lower carboxylic acids or mixtures of vinyl esters of lower carboxylic acids with up to 50 mole percent of esters of acrylic or methacrylic acid. The compounds can be used to advantage as reaction components having hydroxyl groups in the production of polyurethanes. In particular, they improve the mechanical properties of polyurethane foams, such as, for example, their compression hardness.

标 题:Purification of glycerin obtained as a bioproduct from the transesterification of triglycerides in the synthesis of biofuel

权利人:JOHANN HALTERMANN LTD
摘要:Methods for purifying glycerin contaminated with one or more lower boiling alcohols such as methanol, ethanol, straight, branched or cyclic C3-C6 alcohols, and the like. The methods are particularly useful for purifying crude glycerin phases recovered from the synthesis of biofuels. The present invention uses distillation techniques to strip alcohol contaminants from glycerin. In contrast to conventional methods that carry out distillation either under substantially anhydrous or very wet conditions, the present invention carries out distillation in the presence of a limited amount of water, e.g., from about 0.8 to about 5 parts by weight of water per 100 parts by weight of contaminated glycerin to be purified.

标 题:Methanol synthesis using a catalyst combination of alkali or alkaline earth salts and reduced copper chromite

摘要:The present invention relates to a novel route for the synthesis of methanol, and more specifically to the production of methanol by contacting synthesis gas under relatively mild conditions in a slurry phase with a catalyst combination comprising reduced copper chromite and basic alkali salts or alkaline earth salts. The present invention allows the synthesis of methanol to occur in the temperature range of approximately 100°-160° C. and the pressure range of 40-65 atm. The process produces methanol with up to 90% syngas conversion per pass and up to 95% methanol selectivity. The only major by-product is a small amount of easily separated methyl formate. Very small amounts of water, carbon dioxide and dimethyl ether are also produced. The present catalyst combination also is capable of tolerating fluctuations in the H 2 /CO ratio without major deleterious effect on the reaction rate. Furthermore, carbon dioxide and water are also tolerated without substantial catalyst deactivation.
