[0041] The following is attached Figure 1-4 The application is described in further detail.
[0042] The embodiment of the present application discloses a method for synthesizing methoxyamine hydrochloride. refer to figure 1 , figure 2 , the method for synthesizing methoxyamine hydrochloride comprises the steps:
[0043] S1. Add water and sodium hydroxide to reactor 1, stir and dissolve at room temperature, then add butanone oxime and a phase transfer catalyst, wherein the phase transfer catalyst is PEG500;
[0044] S2. Cool the inside of the reactor 1 to 0-15°C, specifically, to 5°C, and add a methylating reagent to the reactor 1, wherein the methylating reagent is dimethyl sulfate;
[0045] S3. After the addition is completed, react at a temperature of 10°C for 4 hours, then cool to below 5°C and stand to separate layers to obtain an organic layer and a water layer, distill the water layer and collect the distillate, then combine the oil layer and the distillate, and t...
