摘要:合成润滑剂(聚α-烯烃,Pao)的成熟制造是通过石化乙烯的低聚,聚合和加氢反应进行的.在这项工作中,我们利用廉价的生物来源油酸作为原料,通过全碳链合成而无碳损失地合成了rot型c 45生物润滑油基础油.它包含多个级联化学过程:将油酸氧化为壬二酸(进一步酯化为壬二酸二甲酯)和壬酸(均为c 9链).然后将后者选择性地氢化成壬醇,并溴化成溴格里雅试剂.下一步,通过亲核加成(npa)过量的c 9形成c 45生物润滑油基础油.溴化格氏试剂与壬二酸二甲酯,然后进行加氢脱氧.所制备的生物润滑油基础油的具体性能几乎与商用润滑油pao6(exxonmobil)的性能相同.该工艺为生产增值生物润滑油基础油提供了一条新的有希望的途径.

摘要:The present disclosure provides a method for producing one or more intermediates for the synthesis of one or more ionizable lipids, the method comprising: (i) producing a beta-ketoacid by reacting a cyclic ester, a terminal hydroxyester or a derivative thereof, a dicarboxylic acid half ester, or an acid chloride derivative of the dicarboxylic acid half ester, in a condensation reaction, thereby producing the beta-ketoacid or a beta-ketoester that is hydrolyzed to produce the beta-ketoacid; and (ii) decarboxylating the beta-ketoacid, thereby producing the one or more intermediates, wherein the one or more intermediates have a structure that may be defined by Formula A. Further provided is a method for producing ionizable lipid from the intermediate comprising adding an ionizable head group moiety to (a) a ketone group of one or more intermediates having the structure that may be defined by Formula A; or (b) a corresponding alcohol of the intermediate.

摘要:A method is described for producing saturated dicarboxylic acids with a chain length of C6 to C21 or the corresponding diamidic dicarboxylic acids from fatty acid cleavage of unsaturated fatty acids or the bis-fatty acid diamides of these unsaturated fatty acids by oxidative ozonolysis and subsequent separation and purification of the dicarboxylic acids, whereby after oxidative ozonolysis, the reaction products are dissolved at a high temperature in a carboxylic acid or a mixture of several carboxylic acids with a medium chain length of C6 to C12 or esters of short-chain alcohols of these carboxylic acids as the recrystallization solvent.

摘要:The present invention relates to an isocyanate-free and preferably solvent-free process for preparing polymers containing five-membered cyclic carbonate groups. In particular, the present invention is directed to a process for preparing polymers bearing cyclic carbonate groups by reacting carboxyl-bearing polymers selected from the group including polyesters based on di- or polyols and di- or polycarboxylic acids or derivatives thereof or poly(meth)acrylates, with hydroxyl-functionalized five-membered cyclic carbonates, without addition of isocyanates.

标题:Synthesis of high solids resins from amine terminated polyamides
发明人：MASLANKA WILLIAM W
权利人:HERCULES CORP
摘要:The present invention contemplates a process for forming polyaminoamide polymers formed by the reaction of a dibasic acid/ester with excess amounts of an amine; the intermediate polymer resulting therefrom; a process for synthesizing effective, high solids resins resulting from the reaction of intermediate polymers with an epihalohydrin; and the resultant high, solids resin. These resins may be used as wet strength resins in the papermaking industry.
