Method for preparing IPDI (isophorone diisocyanate)

The invention discloses a method for preparing IPDI (isophorone diisocyanate). The method comprises the following steps: (1) isophorone and hydrogen cyanide are subjected to a reaction in the presenceof a catalyst to obtain isophorone nitrile; (2) isophorone nitrile obtained in step (1), ammonia and hydrogen are subjected to a reaction in the presence of a catalyst to obtain isophorone diamine; (3) isophorone diamine is subjected to a phosgenation reaction to obtain IPDI, wherein the content of impurities containing secondary amine groups in isophorone diamine subjected to the phosgenation reaction in step (3) is smaller than or equal to 0.5wt%, preferably smaller than or equal to 0.3wt%, and more preferably smaller than or equal to 0.1wt%. By means of the method, content of hydrolyzed chlorine in the IPDI product can be effectively reduced, the yellowing resistance of the product is effectively improved, and the harm that downstream products are unqualified due to existence of hydrolyzed chlorine in the product is reduced.

3-aminomethyl -3, 5, 5-trimethyl method for preparing cyclohexylamine (by machine translation)

The present invention provides a 3-aminomethyl -3, 5, 5-trimethyl method for preparing cyclohexylamine. 3-cyano -3, 5, 5-trimethyl cyclohexyl imine the inferior amination reaction material, in the subsequent steps, with the assistance of the circulating material in the 1st 1st-stage hydrogenation reaction by the hydrogenation reaction material, and can effectively inhibit the generation of HCN product, then in the heating can decompose under the action of the alkaline additive to 2nd stage hydrogenation reaction, then heating the alkaline additive decomposition, decomposition reaction material as circulation material part of a 1st-stage hydrogenation reaction to return as adjuvant, 3rd levels of the remaining part of the hydrogenation reaction, to obtain 3-aminomethyl -3, 5, 5-trimethyl cyclohexane, in the product can be effectively reduced 3-cyano -3, 5, 5-trimethyl cyclohexane and secondary amines the content of the product.

METHOD FOR PREPARING 3-AMINOMETHYL-3,5,5-TRIMETHYL CYCLOHEXYLAMINE

The present invention provides a method for preparing 3-aminomethyl-3,5,5-trimethyl cyclohexylamine. The method comprises: a) reacting 3-cyano-3,5,5-trimethyl cyclohexanone with excess primary amine as well as removing the water generated from the reaction, so that IPN is substantially converted into imine compounds; b) in the presence of an ammonolysis catalyst, mixing the product of step a) with liquid ammonia, making the imine compound perform ammonolysis reaction to generate 3-cyano-3,5,5-trimethyl cyclohexylimine and the primary amine; and c) in the presence of hydrogen and a hydrogenation catalyst, hydrogenating 3-cyano-3,5,5-trimethyl cyclohexylimine obtained in step b) to obtain 3-aminomethyl-3,5,5-trimethyl cyclohexylamine. The method of the present invention avoids the generation of 3,5,5-trimethyl cyclohexanol and 3-aminomethyl-3,5,5-trimethyl cyclohexanol as the major by-products in the prior art, thereby improving the yield of 3-aminomethyl-3,5,5-trimethyl cyclohexylamine.
