Some examples of dibasic acids include, but are not limited to, dibasic fatty acids, phthalic acid, isophthalic acid, carboxy terminated polybutadiene, carboxy terminated acrylonitrile-co-butadiene (CTBN), and long chain carboxy terminated products produced by reacting aliphatic diamines with dibasic ac...
Acid or basic catalysts such as sodium methoxide, trimethylbenzylammonium hydroxide, tetramethylammonium hydroxide, hydrogen chloride or toluene sulphonic acid in amounts from about 0.5 to 10 per cent may be used, the quaternary ammonium bases being preferred. About 0.1 to 2 per cent of a ...
In examples: (1) 3-acetylthio-7-carboethoxyheptanoyl chloride is prepared by treating the appropriate acid with excess of thionyl chloride at room temperature; (2) and (3) the (+)- and (-)-enantiomorphs are similarly prepared from the (+)- and (-)-enantiomorphs of 3-acetylthio7 - ...
Mercapto-substituted esters are prepared by esterifying a dibasic carboxylic acid, preferably one containing from 6 to 12 carbon atoms, with a mercapto-alcohol containing from 2 to 4 carbon atoms. In the examples esters are prepared by refluxing in the presence of p-toluene-sulphonic acid ...
