Abstract:Study a improved synthetic technology for o-methyl phenylthiourea. These problems of materials solidify,mixed hard,reaction delayed and increase cost etc. in the old process strive to be resolved by using homogenate agent. The yield of the target compound reached to 93% and the purity greater than 98%.
Key words:o-methyl phenylthiourea;tricyclazole;synthesis
