专利号:US-8569560-B2 优先权日:2006-10-13 标题 :Synthesis of terminal alkenes from internal alkenes via olefin metathesis 发明人:SCHRODI YANN; PEDERSON RICHARD L; KAIDO HIROKI; TUPY MICHAEL J 权利人:ELEVANCE RENEWABLE SCIENCES 摘要:This disclosure relates generally to olefin metathesis, and more particularly relates to the synthesis of terminal alkenes from internal alkenes using a cross-metathesis reaction catalyzed by an olefin metathesis catalyst. According to one aspect, for example, a method is provided for synthesizing a terminal olefin, the method comprising contacting, in the presence of a ruthenium alkylidene metathesis catalyst, an olefinic substrate comprised of at least one internal olefin with a cross metathesis partner comprised of an alpha olefinic reactant, under reaction conditions effective to allow cross-metathesis to occur, wherein the reaction conditions include a reaction temperature of at least 35° C. The methods, compositions, reactions and reaction systems herein disclosed have utility in the fields of catalysis, organic synthesis, and industrial chemistry.

专利号:US-5872245-A 优先权日:1992-09-30 标题 :Continuous process for the synthesis of sucrose fatty acid esters 发明人:WILSON DONALD C 权利人:OPTIMA TECHNOLOGIES GROUP 摘要:This present invention pertains to a process for the synthesis of sucrose fatty acid esters by reacting sucrose and a purified specific fatty acid ester under substantially solvent free conditions in the presence of a transesterification stationary catalyst and mechanical emulsification. The process is continuous, yielding selected individual products of separated simple sucrose fatty acid esters of mono-, di-, tri- and polyesters while recycling the unwanted ester fractions, the unreacted sucrose and fatty acid ester.

专利号:US-5338686-A 优先权日:1992-04-29 标 题:Method for measuring in vivo synthesis of biopolymers 发明人:HELLERSTEIN MARC K 权利人:HELLERSTEIN MARC K 摘要:A method for determining the mass isotope enrichment of a subunit from which a biopolymer is formed, and the rates of synthesis and decay of the biopolymer. The mass isotope enrichment of the subunit is determined by comparing the mass isotopomer distribution of the biopolymer after administration of a mass isotopically labeled subunit, with the expected frequencies of the different mass isotopomers produced from a given subunit mass isotope enrichment. To determine the synthesis rate of the biopolymer, the expected frequency of a selected biopolymer mass isotopomer, calculated from the subunit isotope enrichment, is compared with the actual frequency of that biopolymer mass isotopomer. To determine biopolymer decay, the decay rate of high mass isotopomers of the biopolymer is determined.
