双吡唑啉酮类螯合剂BPMOPB的性能

A STUDY ON THE PROPERTIES OF NOVEL CHELATING AGENT BPMOPB

测定了双吡唑啉酮类螯合剂1,4-双(1′-苯基-3′-甲基-5′-氧代吡唑啉-4′-基)丁二酮-[1,4](BPMOPB)的色质联谱、质子核磁共振谱及红外光谱。还通过pH电位滴定法,测定了BPMOPB的酸离解常数及它在水和氯仿中的两相分配常数。

The novel chelating agent 1, 4-bis (1′-phenyl-3′-methyl-5′-oxo-pyrazole-4′- yl) butanedione-[1,4](BPMOPB)has been synthesized. Its properties, including GC/MS, NMR, and IR spectra have been determined. And its acid dissociation con- stants and two-phase distribution coefficients have been obtained with PH poten- tial titration method.
