| titleOfInvention | Preparation method of furfuryl acetylene alcohol |
| abstract | The invention provides a preparation method of furfuryl acetylene alcohol, which comprises the following steps of preparing acetylene and furfural as raw materials; the catalyst is a composite catalyst composed of crown ether and alkali metal salt. According to the invention, water and toluene/ethylbenzene/xylene are used as solvents, a specific catalyst and other reaction conditions are combined, so that the conversion rate of the raw materials is 85-95%, and the product yield is 87.7-93.5%; on the premise of improving the reaction yield, the layered recovery and reuse of the catalyst after flash evaporation are realized, the reaction reuse yield is not obviously reduced, the conversion rate of eight continuous batches of reaction reuse is 83-95%, and the reaction yield is 86-92%; the amount of solvent used is reduced. |
