| titleOfInvention | Method for preparing hexamethylene-1,6-diisocyanate (HDI) by heterocatalytic pyrolysis in liquid phase |
| abstract | The invention belongs to the technical field of organic chemical engineering, and relates to a method for preparing hexamethylene-1,6-diisocyanate (HDI) by heterocatalytic pyrolysis in a liquid phase. A low-boiling solvent and a supported solid catalyst are adopted, the reaction temperature is 180-250 DEG C, the pressure is kept at 0.2-2 MPa, and alkyl alcohol generated by the reaction is transferred out of the system along with nitrogen. The conversion rate of the hexamethylene diamino acid ester is higher than 96%, and the product yield is up to higher than 88%. The invention is simple to operate, and has the advantages of high production safety and reliability, and no environment pollution; and the catalyst and solvent can be easily separated from the product, thereby having high recycling performance. |
