Physical and Chemical Properties | The pure product is a colorless oily liquid, which decomposes in water and air, and is soluble in solvents such as acetonitrile and xylene. |
Use | O-(β-chloroethoxy)-benzenesulfonyl isocyanate is an intermediate of sulfonylurea herbicide ether sulfuron. |
production method | its preparation method is to add xylene and o-(β-chloroethoxy) benzenesulfonamide in the reaction kettle, then add n-butyl isocyanate, refluxing at the temperature for 1 5min, then passing phosgene at 130 ℃ for about 6-7h, after passing through the phosgene, normal pressure evaporates n-butyl isocyanate and xylene, the residue is o-(β-chloroethoxy) benzenesulfonyl isocyanate. |
