摘要:生物有机硫化物与几种金属离子的电子转移反应以生成硫化物自由基阳离子是生物化学过程中非常关注的问题.为了理解其机理,研究了具有模型化合物铁(III)-联吡啶与硫代二乙醇酸(tdga)的受激生物系统.光谱研究揭示了在高氯酸水溶液中反应的动力学和热力学.该反应分别相对于[fe(bpy)3](3+)和tdga分别为0.412的第一级和分数级.氧化对[h(+)]的变化不敏感,但随着离子强度([i])的增加而略有降低.加入自由基清除剂丙烯酰胺对反应速度没有影响.δs(#)的高负值(-74.3+/-1.09 Jk(-1)mol(-1))表示形成的配合物的确定方向高于反应物.基于以上结果,提出了适合该反应的反应机理.

标 题:Flow synthesis of organic adsorbents and a flow photo-reactor for the adsorption and degradation of contaminants in water sources
发明人：KHALIL SAFIYA; VERDUZCO RAFAEL; ALAZMI ABDULLAH
权利人:UNIV RICE WILLIAM M
摘要:A method of making a covalent organic framework includes continuously feeding a first precursor and a second precursor to a flow reactor; heating, and mixing the first and second precursors; nucleating and growing the covalent organic framework; and continuously outputting the covalent organic framework from the third section of the flow reactor. A photo-reactor for treating contaminated water includes: a light source; an enclosed channel around the light source; a cover comprising one or more lights illuminating the enclosed channel; and a covalent organic framework cased within the enclosed channel, where the covalent organic framework is photo-catalytically active for degrading a contaminant in the contaminated water so as to produce treated water. A method of treating contaminated water includes feeding the contaminated water to the photo-reactor and contacting the contaminated water with the covalent organic framework.

发明人：TSUI MOSUM E; SHERWIN MARTIN B
权利人:GRACE W R & CO
摘要:A process for forming thioglycolic acid by contacting in a reaction zone at elevated pressure of at least 250 psig a mixture of monochloroacetic acid and dichloroacetic acid with a molar excess of an alkali metal hydrosulfide to form the alkali metal salt of thioglycolic acid, acidifying said salt and removing the free thioglycolic acid. A preferred process further requires separating any formed thiodiglycolic acid from the resultant liquid phase materials and recycling said acid to the reaction zone.
