Route of Synthesis (ROS)
| Conditions | Yield |
| With hydrogen In water at 375℃; for 5h; Experimental Procedure Preparation of Caprolactone [0243] 10 ml of catalyst 4 reduced beforehand at 450° C. and 5 ml of glass powder used as static mixer vaporizer are placed in a vertical glass reactor 22 mm in diameter. [0244] The catalytic bed is heated under a stream of 5 l/h of hydrogen to 375° C. [0245] After stabilizing the catalytic bed under these conditions for 30 minutes, injection onto the catalytic bed, by means of a syringe pump, of an aqueous adipic acid solution at 2percent w/w at a flow rate of 10 ml/h is commenced. [0246] The reaction gas stream is then condensed in a receiver immersed in an ice-water bath. [0247] After injection for 5 hours under these conditions, the condensates are analyzed by GC. [0248] For a degree of conversion of 100percent, an 85percent yield of caprolactone is obtained. | 85% |
| With hydrogen; Ru4(CO)82(PBu3)4 In diethyl ether; toluene at 180℃; under 98800 Torr; for 48h; Yield given; | |
| With hydrogen In 1,4-dioxane at 265℃; under 18751.9 Torr; Experimental Procedure Production of ε-caprolactone from the adipic acid through the hydrogenation reaction [catalyst: CuO(80)SiO2 (20)]The catalyst was produced by using the same method as Example 1. The reaction temperature was fixed to 265°C, the reaction was performed by using the same method as Example 1, and the reaction results over time are described in the following Table 7. The present catalyst exhibited high selectivity of 86.5percent of ε-caprolactone. |
