application | m-chlorobenzene isocyanate is a carboxylate organic substance and can be used as an organic intermediate. |
use | 3-chlorophenyl isocyanate is an intermediate of the herbicide chloraniline. |
production method | its preparation method is to add toluene to the reaction kettle, pass a certain amount of phosgene under cooling, then drop the toluene solution of m-chloroaniline into the reaction kettle, continue to stir for a certain period of time after adding, then move the material into the thermal reaction kettle, continue to pass phosgene and slowly raise the temperature to a certain temperature, at this time, a large amount of hydrogen chloride and phosgene escape, after condensation, it is absorbed with toluene, and then continues to pass into the phosgene reaction until the reaction ends when the material is transparent. Nitrogen is introduced to exhaust phosgene and hydrogen chloride, and then the material is moved to the desolation kettle to remove toluene to obtain the finished product. |
