carboxylic acid Thesaurus Medical Acronyms Encyclopedia Wikipedia Related to carboxylic acid:carboxylic acid derivatives car·box·yl·ic acid (kär′bŏk-sĭl′ĭk) n. An organic acid that contains one or more carboxyl groups. American Heritage® Dictionary of the English Language, Fifth Editi...
Carboxylic acids are named after their hydrocarbon moiety, and have the suffixic acid (Box 2.10). Carboxylic acids are very reactive. They readily form esters with alcohols (or lactones when the alcohol group is within the same molecule) and amides with amines. View chapterExplore book ...
Carboxylic acid higher alcohol ester-trimethyl ammonium chloride and application thereof in clay stabilizer本发明的羧酸高碳醇酯基三甲基氯化铵及在粘土稳定剂中的应用,兼具驱油与防膨的双重功效,尤其适用于低渗透,水敏性原油储层,其主要成份由质量份10～30%羧酸高碳醇酯基三甲基氯化铵,1～20%三甲胺盐酸盐及50...
生物蛋白中的多糖组分含有glucuronic acid 单元(也就是glucose的C-6是羧酸的形式),现在想把它还原成 Glucose,请教有机的虫虫们指点可用的反应。 限制条件: 起始量很少,只有40-100微克。所以要求反应必须高效,没有付产物。 万分感谢!! 我的初步想法是先把glucuronic acid esterificaiton,再用NaBH4来还原。但是esterif...

Carboxylic acid R-COOH or HOOC-R-COOH (where R is opt. halogenated 2-35 C satd. aliphatic group, phenyl or phenylene), stable under reaction conditions, is used as alcoholysis catalyst, in 0.005-0.15 wt.%/wt. reaction mixture, for production of linear high molecular polycarbonates by alcoho...
N-protectedamino acidand peptideS-phenyl esters, which are useful building blocks in peptide synthesis, are obtained in excellent yields withoutracemization.37N-Hydroxyphthalimide38and DMAP39have been used as cocatalysts to facilitate the reaction. The preparation of the Wittig reagent (5) by this ...
1. Process for the manufacture of a carboxylic ester by an esterification reaction of a carboxylic acid and an alcohol comprising at least the following stages: a) feeding at least one alcohol and one carboxylic acid to a reactor; b) reacting the alcohol and the acid in the presence of an...
