摘要:开发可以替代贵金属基催化剂的非贵金属基加氢催化剂是非常理想的,但在科学和技术上都具有挑战性.在此,我们提出了一种简便且环保的方法来合成松针生物质衍生的氮掺杂碳负载co 3 O 4纳米粒子(co 3 O 4 /pnc).整个过程包括用硝酸钴盐浸渍松针,然后在氮气气氛下在 500oc 下热解.应用这种 Co 3 O 4 /pnc 纳米催化剂,可产生多种取代酚和功能性有机化学品,包括n-和o-杂芳烃,可以有效地转化为其相应的环氢化产物,产率从非常好到优异(> 55个例子).此外,这种催化方法已被证明可用于制备克级的七种关键药物中间体,这些中间体通常用于批量生产活性药物成分.有利地,环己烷甲酸,吡喹酮的关键药物结构单元,是由聚苯乙烯以两步法合成的.通过高分辨率透射电子显微镜,X 射线光电子能谱,X 射线衍射,N 2彻底研究了新鲜和废 Co 3 O 4 /pnc 纳米催化剂的关键物理化学性质.吸附-解吸,拉曼分析,H

标 题 :Process for the synthesis of tertiary phosphine oxides, and new tertiary phosphine oxides
发明人：BOILEAU SYLVIE L; N GUYEN THANH-DUNG; GAUTIER JEAN-CLAUDE C
权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The invention relates to the synthesis of tertiary phosphine oxides and also to certain tertiary phosphine oxides. According to the invention, an organic phase containing a halogenomethyl derivative, a secondary phosphine oxide and a phase transfer catalyst in an organic medium is reacted with an aqueous phase containing an inorganic base. The halogenomethyl derivative can be a micromolecule or a macromolecule. The tertiary phosphine oxides are substances which are useful, in particular, in fireproofing, in hydrometallurgy and in the field of plant health.

标 题:Phase transfer catalyst for use in the synthesis of polyol fatty acid polyesters
发明人：CORRIGAN PATRICK J; HOWIE JOHN K
摘要:A reaction mixture for manufacturing polyol fatty acid polyesters comprises a polyol, a fatty acid lower alkyl ester, a base initiator and a phase transfer catalyst. The phase transfer catalyst can be a quaternary ammonium compound, a crown ether, a polyethylene glycol, a polyethylene glycol ether, a polyethylene glycol ester or mixtures thereof. The process of making polyol fatty acid polyesters is carried out at low temperatures and essentially in the absence of a solvent or emulsifier. The polyol fatty acid polyester product stream produced by the foregoing process and reaction mixture has a lower concentration of reaction by-products such as di-fatty ketones and beta-ketoesters and of caramelized by-product which results from the breakdown of the polyol reactant.
