Selected through research and screening of the of dozens more commonly used method of synthesis of t-butylamine, methyl tert-butyl ether (MTBE) catalyzed ammoniation method and isobutylene (IBE) catalyzed ammoniation method to synthesize tert-butylamine, and because the latter have a more The big superiority experimental main isobutylene catalyzed ammoniation. During the catalytic amination of methyl tert-butyl ether tert-butylamine, respectively, Co-Al 2 O 3 (A) and the H-of ZSM-5 (B) as a catalyst experiment to determine a suitable catalyst for the H-ZSM-5, the appropriate reaction conditions: material ratio n (MTBE): n (the NH 3 ) = 1:4 (mol: mol) , temperature of 190 ℃ (A) / 300 ℃ (B), pressure 0.90MPa, airspeed 1.10h -1 (A) / 0.90h -1 (B). To obtain a better yield: 9.80% (A) / 14.80% (B). Isobutylene catalyzed ammoniation Synthesis of tert-butylamine process, the improvement of the equipment is a very important part. The commonly used one-way reaction tube improved into the circulation tube reactor to the breaking of the thermodynamics of the reaction equilibrium. Subsequently, improved turn loop tubular reactor into the circulation tube reactor with a distillation apparatus, to thereby obtain a better separation, and to obtain higher yield. This improved equipment to synthesize tert-butylamine is unprecedented. The same time, the catalyst preparation and screening. (Co)-H-ZSM-5 (A), Co-HY (B), β (Fe Cr) (C) H-ZSM-5 (D), and Cu, Ni, Zn/H-ZSM-5 the five catalyst (E), the catalytic effect of the reaction sequence as follows (C)> (D)> (A)> (E)> (B), the catalytic effects the best catalyst for the (C): β (Fe Cr). Finally, the use of a suitable catalyst and a reasonable reaction apparatus, suitable reaction conditions as follows: the molar ratio of n (IBE): n (NH 3 ) = 1:0.3 (mol: mol), the temperature of the reaction tube 220 ° C and the tower reactor temperature of 140 ° C, reaction time 8h. To obtain a satisfactory yield of 40.2%, which are higher than yield any literature. Tert-butylamine has a wide range of uses in synthetic rubber accelerators, pharmaceuticals, pesticides, dyes, coloring agents, lubricants additives. The study, in the filter catalyst on the basis of the equipment be improved to obtain better results, this experiment is very advantageous. The findings of this paper have important significance for either academic or practical application.
