- 中文摘要: Enethiol contents of 1, 5-diphenyl 2, 4-dithiobouret (DP); 1, 5-di-p-tolyl2, 4-dithiobiuret (DPT); 1-phenyl 5-p-tolyl 2, 4-dithiobiuret (PPT); 1-phentl 5-o-tolyl 2,4-dithiobiuret (POT); 1-phenyl 5-o-toly 2, 4-dithiobiuret (MPT) have been studied by alkali titration method in methanol and by spectrophoto-metric method in different solvents of varying polarities, ranging from pyridine (Z, 64.0) to methanol (Z, 83.6). Free energy of tautomerisation has been cal-culated. The effect of substituents on the phenyl group on enethiol contents has been studied. It has been observed that temperature has no effect on enethiol-thione equilibrium.
