[Study on the stability of N-alkyl-N'-(sodium p-aminobenzenesulfonate) thiourea].
In this work, the stability of 13 kinds derivative of thiourea were studied by the UV absorption spectra and IR spectra of thiourea compounds in acidic medium at pH = 4.00, neutrality medium at pH = 7.00, basic property medium at pH = 10.00, under the influence of diffeveut store time, oxygen and sun light. Their structures were discussed and the changing rules of stability were developed.
