摘要：

Selected chiral carboxylic acids (mandelic acid, phenylpropionic acid and phenylbutyric acid) were selectivity extracted from diatomaceous earth with supercritical CO2 on addition in situ of (R)-(+)- or (S)-(-)-methylbenzylamine as a chiral base. In all cases, a remarkable partial resolution (61-95%) was achieved on an analytical scale. Pressure, temperature and extraction time as well as the mole ratio of base and acid had a marked influence on the quantitative extraction of the products. (C) 1999 Elsevier Science B.V.
