Preparation method of 2,4,6-toluene triisocyanate

The invention provides a preparation method of 2,4,6-toluene triisocyanate, which comprises the steps of 1, under the catalytic action of nitrogen-doped porous carbon supported palladium, taking 2,4,6-trinitrotoluene as a raw material to obtain 2,4,6-triaminotoluene hydrochloride; and 2, taking 2,4,6-triaminotoluene hydrochloride as a raw material, and carrying out phosgenation reaction and reduced pressure distillation to prepare 2,4,6-toluene triisocyanate. The catalyst nitrogen-doped porous carbon loaded palladium adopted by the invention has the characteristics of simple preparation, low palladium loading capacity, efficient catalysis and reusability, and the production cost can be obviously reduced. Each step has the advantages of simple operation, high reaction conversion rate, easyseparation and collection of intermediate and final products, and the like. The preparation method has the advantage of low overall difficulty. Moreover, all intermediate products in the method are high in reaction activity, can be fully reacted, have few by-products, and are more beneficial to realizing high-quality production of 2,4,6-toluene triisocyanate.
