Production method
It is obtained by the reaction of γ-butane ester with methylamine. The first step in the reaction is to γ-butane ester and methylbutylamine to produce 4-hydroxy-N-methylbutylamide, and the second step is to dehydrate to produce N-methylatonin. The two-step reaction can be carried out continuously in a tube reactor, with a molar ratio of γ-butane to methylamine of 1:1.15, a pressure of about 6MPa and a temperature of 250 degrees C. After the reaction is completed, the finished product is distilled by concentration and decompression. The yield is 90%. If the use of kettle-type anti-inverter production, the amount of methamine is 1.5-2.5 times the theoretical amount, to take laboratory preparation as an example. In a 500 ml heat press, add 2 mol-butane ester and 4 moles of liquid methamine, closed heating, and keep warm at 280 degrees C 4h. After cooling, release excess methylamine, distillation, collection of 201-202 degrees C fractions, about 180g of the product, the yield of about 90%. Raw material consumption (kg/g) γ-butane 980 methamine (40%)860
