- W2373062402 abstract "Separation of trans _ dichlorochrysanthemic acid(DCCA) and cis _ DCCA was performed by using their different dissolubility and pKa value, satisfactory results were obtained with yield of 83.7% for trans _ DCCA and 88.9% for cis _ DCCA. Optical isomers of cis _ 2,2 _ dimethyl _ 3 _ (2,2 _ dichlorovinyl)cyclopropanecarboxylic acid, which is a key intermediate for the preparation of cis _ 2,2 _ dimethyl _ 3 _(2,2 _ dichlorovinyl)cyclopropanecarboxylate pesticide, were separated by using S(-) _ α _ phenylethyl amine as a derivatization reagent. Its optical and racemic isomers reacted with S(-) _α _ phenylethyl amine to form their amidates, which were purified by TLC, then determined by HPLC with a reference of the amidate of the cis _ racemic acid. The optical purity of cis _ R(+) _ and cis _ S(-) _ 2,2 _ dimethyl _ 3 _(2,2 _ dichlorovinyl)cyclopropanecarboxylic acid was 93.7% and 81.8%, respectively. Optical purity of trans _ 2,2 _ dimethyl _ 3 _ (2,2 _ dichlorovinyl) cyclopropanecarboxylic acid can be analyzed by a similar method." @default.
