摘要

The BMPPT(4-benzoy1-2, 4-dihydro-5-methy1-2pheny1-3H-pyrazol-3-thione)was synthesized from BMPP. Its m.p. is 106-108 deg.c. The results of the element anaysis are as fol- lows: C, 68.51/100, H, 4.51/100, N, 9.26/100, S, 11.47/100, which are in conformity with the theoretical value(C, 69.15/100, H, 4.76/100, N, 9.52/100, S, 10.90/100). The solvent extraction of Th~4+ from nitric acid solution by BMPPT in benzene was studied. The solvent extraction ability of BMPPT is not so high as that of its Parent(BMPP).
