标题:通过茂锆氢化物催化仲酰胺和叔酰胺的轻度发散半还原转化
摘要:酰胺温和催化部分还原为亚胺已被证明是一种具有挑战性的合成转化,许多过渡金属直接将这些底物还原为胺.在此,我们报告了一种通过二茂氢化物催化半还原仲酰胺和叔酰胺的温和催化方法.仅使用 5 Mol% 的 Cp 2 Zrcl 2,仲酰胺的还原脱氧即可提供多种亚胺,产率高达 94%,具有优异的化学选择性,且无需手套箱操作.此外,当催化方案在伯胺存在下于室温下进行时,也可以实现叔酰胺的新型还原氨基转移,从而以高达 98% 的收率获得更多的亚胺.通过轻微的程序调整,酰胺到亚胺,醛,胺或烯胺的单烧瓶转化是可行的,包括多组分合成.

标题 :Use of multigene stacking method in synthesis of nervonic acid in brassica napus

摘要:The present disclosure relates to use of a multigene stacking method in synthesis of nervonic acid in Brassica napus. The present disclosure provides a multigene co-expression plant vector, including an initial backbone of pBWA(V)BII and multiple exogenous gene expression cassettes. The present disclosure further provides two plant vectors applicable to genetic transformation, including a three-gene co-expression plant vector and a five-gene co-expression plant vector. In the present disclosure, after the three-gene co-expression plant vector and the five-gene co-expression plant vector are separately transferred into the Brassica napus, the nervonic acid (NA) with a high content is synthesized in the Brassica napus through multigene co-expression. An NA ratio can be significantly increased combined with a higher seed oil content and a greater field seed yield. The plant vector realizes efficient synthesis of NA in oil crops, obtains NA-rich seed oil, and increases an added value of edible oil.

权利人:AIR LIQUIDE
摘要:The invention relates to a process and plant for production of methanol by heterogeneously catalyzed reaction of hydrogen and carbon oxides in methanol synthesis reactors, while reducing carbon dioxide emissions According to the invention, carbon dioxide is removed from a raw synthesis gas or shifted synthesis gas. From the carbon dioxide removed raw synthesis gas or shifted synthesis gas, different hydrogen containing gas streams are generated in a hydrogen recovery stage. The different hydrogen containing gas streams as well as the carbon dioxide removed raw synthesis gas or shifted synthesis gas can be used to substitute natural gas fuel in burners, fired heaters, and auxiliary boilers, thus reducing the carbon dioxide emissions from the process or plant.

摘要:The present invention discloses an engineering yeast strain for producing nervonic acids. The yeast strain over-expresses the genes related to enzymes required in a synthetic process of long-chain unsaturated fatty acids, such as fatty acid elongase, desaturase, diacylglycerol acyltransferase and the like, and optionally, further adjusts and controls the synthesis and decomposition route of triglyceride, the synthesis and decomposition route of sphingomyelin, and the synthesis and decomposition route and the oxidation-reduction balanced route of lipid subcell levels. The recombinant yeast strain can produce microorganism oil; and the content of the prepared nervonic acids accounts for 39.6% of the total fatty acids.

标题 :Production of liquid hydrocarbons from carbon dioxide, in combination with hydrogen or a hydrogen source
发明人：MARKER TERRY; WANGEROW JIM; LINCK MARTIN
权利人:GTI ENERGY
摘要:Pathways are disclosed for the production of liquid hydrocarbon products comprising gasoline and/or diesel boiling-range hydrocarbons, and in certain cases renewable products having non-petroleum derived carbon. In representative processes, a gaseous feed mixture comprising CO2 in combination H2 and/or CH4 (or other hydrocarbon source of H2) is converted by reforming and/or reverse water-gas shift (RWGS) reactions, optionally further in combination with Fischer-Tropsch (FT) synthesis and/or cracking. A preferred gaseous feed mixture comprises biogas or otherwise a mixture of CO2 and H2 that is not readily upgraded using conventional processes. Catalysts described herein have a high activity for catalyzing the reforming (including dry reforming) of CH4 and other light hydrocarbons (e.g., those having been produced via FT synthesis and recycled as light ends back to the process) as well as simultaneously catalyzing the RWGS reaction. These attributes allow for flexibility in terms of compositions that may be converted efficiently. Economics of small-scale operations may be improved, if necessary, using an electrically heated reforming reactor in the first or initial reforming stage or RWGS stage.

摘要:A method of implementing organic synthesis reactions uses a composition containing a metal catalyst originating from a calcined plant. The plants can be from the Brassicaceae, Sapotaceae and Convolvulaceae family, and the metal catalyst contains metal in the M(II) form such as zinc, nickel, manganese, lead, cadmium, calcium, magnesium or copper. Examples of the organic synthesis reactions include halogenations, electrophilic reactions, cycloadditions, transesterification reactions and coupling reactions, among others.
