摘要:在恒定离子强度下,六氰合铁酸酯(III)离子在恒定的离子强度下,钌酸离子催化烯丙醇,巴豆醇,肉桂醇和炔丙醇被氧化的动力学表明速率与碱浓度或离子强度无关.该反应显示出对钌酸根离子的一级依赖性,而六氰基高铁酸根(III)离子中的零级依赖性.反应速率随底物浓度的增加而增加,并表现出michaelis-Menten类型的行为.数据表明,氧化是通过在醇分子和钌酸离子之间形成络合物而进行的,从而产生相应的酸.已经在四个不同的温度下研究了该反应,并计算了热力学参数.提出了与实验结果相符的合理机制.

权利人:CHEN LIN; HAN YEUN-KWEI; ROBERTS CHRISTOPHER R
摘要:Methods for the synthesis of cyclic peptides are provided, as well as novel dipeptide compounds. The methods include the solid phase synthesis of a dipeptide, which is the coupled to a second peptide in a solid phase reaction. The peptide is then cyclized following the coupling reaction. The methods and dipeptides are particularly useful for the synthesis of MC-4 receptor agonist peptides.

标题 :Glycolysis of cured unsaturated polyesters for producing a recycle reactant
发明人：TUFTS TIMOTHY A; TSAI CHUNG-CHIEH; HUPP STEPHEN S
权利人:ASHLAND OIL INC
摘要:The present invention is directed to a method for treating cross-linked (cured) filled or untilled unsaturated polyester for deriving an alcohol recycle reactant useful in the synthesis of alcohol-formed derivative products. The first step of the method is the attrition of the cured unsaturated polyester to form particulates thereof. In the next step of the process, at least a fraction of any filler or fiberglass in the cured unsaturated polyester is separated to form a cured unsaturated polyester regrind. The next step is the subjecting of the cured unsaturated polyester regrind to agitated, uncatalyzed or catalyzed glycolysis in the presence of excess glycol and, optionally, a transesterification catalyst under agitation at elevated transesterification temperature. The final step of the process is the recovery of the recycle alcohol reactant for use in the synthesis of alcohol-formed derivative products. The glycolysis reaction is conducted under agitation in order to keep the cured unsaturated polyester regrind solids suspended during the glycolysis reaction. In this regard, establishment of shear conditions should aid in the glycolysis step of the process.

标题:Process for synthesis of allophanate compounds and compositions including the product thereof
发明人：TAZZIA CHARLES L
权利人:BASF CORP
摘要:The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.

标题 :Manufacture of dimethylaminobenzenecarboxylic acid esters
发明人：QUADBECK-SEEGER HANS-JUERGEN; HOCH HELMUT
权利人:BASF AG
摘要:Dimethylaminobenzenecarboxylic acid esters are produced by reaction of nitrobenzenecarboxylic acid esters with formaldehyde and hydrogen under pressure in the presence of a hydrogenation catalyst containing metals of atomic numbers 24 to 29 and of a weak acid, at temperatures from 35° to 150° C. The products are starting materials for the synthesis of dyes, especially of crystal violets, and of reactive dyes and pesticides.

标题:Synthesis of 5-acetoxymethyl furfural in the presence of recyclable salt catalysts
发明人：MELLER ELAD; LEADER AVIA
权利人:CELLUFLUX LTD
摘要:A process for preparing and ester of 5-hydroxymethyl furfural of the formula: (I) wherein R is a linear or branched alkyl or alkenyl, comprising adding to a reaction vessel Ce carbohydrate, organic acid R—COOH and a salt which is at most sparingly soluble in said organic acid to form a reaction mass, heating the reaction mass, allowing the reaction to proceed, separating the salt from the liquid phase and recovering a reaction product comprising an ester of 5-hydroxymethyl furfural.
