| titleOfInvention | Acidic catalyst and hydrogenation catalyst concerted catalysis carbohydrate one kettle way prepare gamma-valerolactone |
| abstract | The invention discloses acidic catalysts and hydrogenation catalyst concerted catalysis carbohydrate one kettle way to prepare gamma-valerolactone, acidic catalyst, hydrogenation catalyst are added in reaction system by this method simultaneously, wherein acidic catalyst is silico-tungstic acid-3- methyl-1-ethylmethylimidazolium sulfonate, phosphotungstic acid-3- methyl-1-ethylmethylimidazolium sulfonate, silico-tungstic acid, trifluoromethane sulfonic acid holmium or aluminum sulfate, and hydrogenation catalyst is Pd/ZrO 2 Or Ru/ZrO 2 , two kinds of catalyst synergistic effect improves the selectivity of levulic acid, significantly improves gamma-valerolactone yield.One kettle way of the present invention directly prepares gamma-valerolactone by carbohydrate, preparation method is simple, stability is good, it is environmentally friendly it is pollution-free, product yield is high. |
