| Abstract: | A purification method of o - methyl formate benzene sulfonamides is obtained by studying the product purification. An optimal synthetic route to synthesize o -methyl formate benzene sulfonamide by using o -methyl formate benzene sulfonyl chloride as starting material is found after contrasting the saccharin method. The most economic and reasonable synthetic route is useful for the synthesis of the sort of sulfonylurea weedicide. |
