Abstract
1,178,423. Resolving (Œ)-trans-chrysanthemum acid. SUMITOMO CHEMICAL CO. Ltd. 27 April, 1967 [27 April, 1966], No. 19398/67. Heading C2C. A process for the resolution of (Œ)-transchrysanthemum monocarboxylic acid comprises adding to a solution thereof in ethanol (at least 500 ml of ethanol per mol of acid being used) at least an equimolar quantity of quinine, separating the (-) acid quinine salt which is precipitated, adding to the mother liquor 45 to 55% of water by volume of ethanol, allowing the mixture to stand and separating the precipitated ( + ) acid quinine salt. Racemic acid may be recovered by adding a large amount of water to the residual mother liquor and decomposing the quinine salt with a mineral acid. The (+) and (-) acid salts are decomposed with a mineral acid to yield the optically pure acid.
