标题:高二氧化硅大孔沸石在水中/水中催化水解疏水酯
摘要:水不溶性酯的水解是工业上重要但具有挑战性的反应,因为在反应过程中酯主要存在于水的油滴中.根据25种非均相和均相催化剂在水上/水中水解水不溶性酯3-苯基丙酸酯的筛选结果,我们发现具有中等si / Al比(si / Al = 75)hβ-75,是一种有效且可重复使用的水解疏水酯的催化剂.用具有不同si / Al比的hβ和hzsm5沸石研究了不同尺寸酯的水解,结果表明疏水性,孔径和布朗斯台德酸位点数量是影响该系统催化活性的关键因素.

标题 :Method for preparing a bimetallic ruthenium/tin catalyst and a process for the synthesis of aldehydes
发明人：JACQUOT ROLAND
权利人:RHODIA CHIMIE SA
摘要:The present invention relates to a new process for the preparation of a bimetallic ruthenium/tin catalyst. The process for the preparation of a bimetallic ruthenium/tin catalyst according to the invention is characterised by the fact that it consists in carrying out the reduction of a ruthenium complex having an electrovalency of -4 and a coordination number of 6, the ligands being either a halogen atom or an anion or a tin halide. The catalyst is further employed for the preparation of aldehydes by reduction, in the vapor phase, of carboxylic acids, esters and anhydrides.

标题 :Enzymatic synthesis of kavalactones and flavokavains
发明人：PLUSKAL TOMÃ?S; Weng jing-ke
权利人:WHITEHEAD INST BIOMEDICAL RES
摘要:Disclosed are methods, compositions, proteins, nucleic acids, cells, vectors, compounds, reagents, and systems for the preparation of kavalactones, flavokavains, and kavalactone and flavokavain biosynthetic intermediates using enzymes expressed in heterologous host cells, such as microorganisms or plants, or using in vitro enzymatic reactions. This invention also provides for the expression of the enzymes by recombinant cell lines and vectors. Furthermore, the enzymes can be components of constructs such as fusion proteins. The kavalactones produced can be utilized to treat anxiety disorder, insomnia, and other psychological and neurological disorders. The flavokavains produced can be utilized to treat various cancers including colon, bladder, and breast cancers.
