摘要:通过将氯磺酸共价接枝到胺官能化的二氧化钛上,已经合成了一种高效且可回收的二氧化钛基纳米催化剂,作为一种新型的无机-有机杂化纳米催化剂,其特征在于通过傅里叶变换红外光谱(ft-Ir),场发射扫描电子显微镜(fe-Sem),X射线衍射(xrd)和热重分析(tga).通过ph分析和哈米特酸度函数确定催化剂的酸强度.使用30%H2O 2有效评估了所得纳米催化剂对硫化物化学选择性氧化为亚砜和硫醇化学成二硫化物的潜力.室温下在无溶剂的条件下用作氧化剂,导致高转化率和高收率.通过中央复合设计(ccd)研究了反应条件的优化,Ccd是最广泛使用的响应面方法之一.该催化剂可以容易地循环使用多达10次而不会显着降低催化活性,这使其成为具有实际应用和大规模应用前景的催化剂.这项工作是第一个使用2,4-甲苯二异氰酸酯作为连接剂将液态酸固定在载体上的报告.

摘要:The synthesis of a larotaxel-fatty alcohol small molecule prodrug with a tumor reduction response characteristic and the construction of a self-assembling nanoparticle, and the use thereof in the preparation of a drug delivery system. Provided is a larotaxel-stearyl alcohol small molecule prodrug, which is prepared into a larotaxel-fatty alcohol prodrug nanoparticle. The larotaxel-fatty alcohol prodrug nanoparticle can be a non-PEGylated larotaxel-fatty alcohol prodrug nanoparticle, a PEG-modified larotaxel-fatty alcohol prodrug nanoparticle, a drug-loaded larotaxel-fatty alcohol prodrug nanoparticle, and an active targeting larotaxel-fatty alcohol prodrug nanoparticle. The larotaxel-fatty alcohol prodrug has few synthetic steps, a simple process, reduced synthesis costs, a high yield and easy purification, and the nanoparticle formed by the self-assembly of the larotaxel-fatty alcohol small molecule prodrug has an ultra-small particle size, which reduces the toxicity and side effects while improving the curative effect of larotaxel.

标 题 :Method of producing allylthioacetic acid

权利人:PORTNYAGINA V; MORGUN M
摘要:The method of producing allylthioacetic acid resides in that allyl bromide is reacted with thiourea at a temperature of 60* to 120* C, then monochloracetic acid is added to the resulting allylisothiouronium bromide and the mixture is heated at a temperature of 60* to 120* C in an alkaline medium, with subsequent isolation of the resulting desired product. Allylthioacetic acid thus produced finds application as a catalyst for acrylonitrile polymerization, for synthesizing other high molecular compounds, as well as for producing new kinds of penicillin and in the synthesis of a number of medicinal preparations.

标 题 :Synthesis of thioglycolic acid
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.

摘要:This invention is directed to a synthesis process for preparing magnesium aluminosilicate clays and to the products of said process. Briefly, a silicon component, an aluminum component, and a magnesium component are combined, under aqueous conditions and at an acidic pH, to form a first reaction mixture and subsequently the pH of the first reaction mixture is adjusted to greater than 7.5 to form a second reaction mixture. The second reaction mixture is allowed to react under conditions sufficient to form the magnesium aluminosilicate clay of the present invention. The invention is also directed to catalyst compositions comprising the magnesium aluminosilicate clays synthesized according to the process of the invention. The resulting magnesium aluminosilicate clay can be used as a catalyst or as a component in catalyst compositions. The invention is further directed to a magnesium aluminosilicate clay with a characteristic 29 Si NMR spectrum and the use of said magnesium aluminosilicate clay in catalyst compositions.

摘要:The present invention provides a method of synthesizing a fluorescently labeled protein in a cell free protein synthesis system, comprising the steps of: (a) incubating a sample of ribosomes obtained from a cell-free extract with plasmid DNA containing a coding sequence for a protein of interest, said sample incubated in a coupled transcription/translation medium together with a aminoacyl tRNA having fluorescent label; (b) partially purifying said fluorescently labeled protein by separating newly synthesized, fluorescently-labeled protein from other fluorescent components within said sample; (c) measuring the amount of protein synthesized; (d) determining fluorescence of newly synthesized protein; and (e) determining the biological activity of the newly synthesized protein.
