| titleOfInvention | Method for producing hexahydrophthalic anhydrides |
| abstract | (57) [PROBLEMS] To solve the problem of hexahydrophthalic anhydrides in which tetrahydrophthalic anhydrides are hydrogenated in a fixed-bed hydrogenation reaction that does not require high pressure, and by-production of hexahydrophthalides is greatly suppressed. A manufacturing method is provided. In a fixed bed hydrogenation reaction of tetrahydrophthalic anhydrides, the supported amount of nickel atoms is 0.1 to 1. Using a nickel-supported molded catalyst of 0%, the reaction temperature is 7 0 ° C to 145 ° C, and reaction pressure is 0.5 MPa to 1.0 M By performing hydrogenation in the range of Pa, high-quality hexahydrophthalic anhydrides with few by-products can be produced in high yield. |
