标题:Fenton和photo-Fenton过程对2,4-二羟基苯甲酸的氧化降解:动力学,机理和o2取代h2O2的证据
摘要:通过fenton和光fenton工艺对2,4-二羟基苯甲酸(2,4-Dhba)氧化降解的动力学和机理进行了详细的HPLC,Ic和toc分析.2,3,4-三羟基苯甲酸(2,3,4-Thba)在早期氧化阶段的形成表明芳环的羟基化是该过程的第一步.该中间体能够还原fe Iii,并有助于fe Ii的循环利用.完全矿化只能在辐照下完成(照片fenton).矿化速率对H2O 2和溶解o浓度的依赖性的详细研究进行了2次.发现即使在H2O 2的初始浓度较低的情况下,只要o 2浓度足够高,则通过光芬顿法完成的矿化过程将在相对较短的时间内完成,这表明o 2至少可以部分替代H2O 2.引导反应途径通向o 2而不是H2O 2消耗对于光芬顿法的技术发展尤为重要.

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.

摘要:It has been discovered that para-xylene (PX) can be synthesized with improved selectivity by reacting an aromatic compound such as toluene and/or benzene with a reactant(s) such as a combination of hydrogen and carbon monoxide and/or carbon dioxide and/or methanol or methylating agents produced therefrom. Catalytic reaction systems are employed, such as crystalline or amorphous aluminosilicates having one-dimensional channel structure, para-alkyl selectivated crystalline or amorphous aluminosilicates, para-alkyl selectivated substituted aluminosilicates, crystalline or amorphous substituted silicates having one-dimensional channel structure, para-alkyl selectivated substituted silicates, crystalline or amorphous aluminophosphates, para-alkyl selectivated crystalline or amorphous aluminophosphates, para-alkyl selectivated zeolite-bound zeolite and para-alkyl selectivated substituted aluminophosphates, and mixtures thereof. The catalytic reaction systems may be selectivated with organometallic compounds, compounds of elements selected from Groups 1 through 16, coke, and mixtures thereof. Using this process, catalyst stability and life is improved.

摘要:A method of improving the adhesion of metathesis compositions, such as ring-opening metathesis polymerization (ROMP) compositions, to a substrate is disclosed, in which an adhesion promoter is added to a polymerizable resin composition in order to improve the adhesion of the polymerizing resin to a substrate material. The addition of the adhesion promoter has been found to provide beneficial improvements in the adhesion of metathesis, especially ROMP, compositions to substrates, particularly glass surfaces, leading to improved characteristics in ROMP materials formed therefrom. The adhesion promoter generally comprises a functionalized silane compound and a peroxide compound. A ROMP composition is further disclosed comprising a cyclic olefin, a ROMP metathesis catalyst, and the adhesion promoter. Polymer products produced via metathesis (ROMP) reactions of the invention may be utilized to provide a wide range of materials and in a variety of composite applications. The invention has utility in the fields of catalysis, organic synthesis, and polymer and materials chemistry and manufacture.
