Embodiment Construction
[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0016] A preparation method for anthranil, comprising the following processing steps,
[0017] b. Add o-nitrochlorobenzene, methanol and 40% sodium hydroxide solution into the autoclave in sequence, raise the temperature in the autoclave to 40° C., and start stirring.
[0018] b. When the temperature in the kettle was raised to 85°C, the pressure was controlled at 0.3MPa to react for 8 hours.
[0019] c. Distill the reaction mixture in b to remove the internal methanol solution, and then add hot water at 70°C for washing.
[0020] d. After the mixture washed in c is left to stand for stratification, the o-nitroanisole is obtained by liquid separation again for use.
[0021] e. Put o-nitroanisole into the high-pressure reactor and add sodium sulf...
