摘要:
Sulfamic acid halides are produced by reaction of sulfamic acids with phosphorus pentahalide in the presence of phosphorus oxyhalide in specific molar ratios and in the presence of halohydrocarbons. The products, some of which are new compounds, are starting materials for the manufacture of plant protection agents, dyes and pharmaceuticals.
