Abstract
The simple synthesis method of 1-Benzoyl-3-(o-chlorophenyl)thiourea by using benzoyl chloride,ammonium thiocyanate and o-chloroaniline as raw material in the presence of PEG-400 as catalyst and methylene dichloride as solvent.The optimum conditions of increase in the product yield were obtained by investigating the influences of reaction temperature,time,solvent and the quantity of raw material.Respectively,elementary,1H NMR and IR analysis proved the structure of product.
