Study on Preparation, Biological Activity and Thermal Decomposition of N-Benzoyl-N＇-(4-Chlorobenzamido) Thiourea
A novel compound N-benzoyl-N＇-(4-chlorobenzamido) thiourea was prepared from benzoyl isothiocyanate which was obtained from benzoyl chloride and potassium thiocyanate, and 4-chlorobenzoyl hydrazine which was obtained from ethyl 4-chlorobenzoate and hydrazine hydrate. IR, 1H NMR, 13C NMR and elemental analysis were utilized to determine the structure of the thiourea. The biological tests indicated that the target compound had antibacterial activity against bacillus subtilis and taphylo-coccus aurers. Meanwhile, the thermal stability was investigated by thermogrativity（TG） and differential thermogrativity (DTG). The results demonstrated there was one weight-loss in the thermal decomposition process. The thermal kinetics equation obtained describing the thermal decomposition process was expressed as .
