On the r-alumina catalyst, the reaction of methanol chlorination to synthesize methylamine is carried out under the following conditions: a ratio of methanol to ammonia of 1:1 to 2 (molar ratio), a reaction temperature of 400 to 440 ℃, a gaseous space velocity of 2000 to 8000 hours, a gas linear velocity of 0.715 to 3.02 cm/s, and a catalyst particle size of 14-60 mesh. The reaction system is within the kinetic control region.
Haohan chromatography uses distillation gas chromatography to determine the concentrations of ammonia, methylamine, and methanol in circulating water, and promptly identifies problems in the production system. The experiment proves that this method is accurate, fast, and easy to operate, and can be promoted and applied in related industries.
