Abstract

The invention discloses a method for preparing furfuryl alcohol through furfural liquid-phase catalytic hydrogenation. A hydrogenation catalyst adopted in the method is prepared through the followingsteps: uniformly mixing a solid nickel source and a solid nitrogen source according to the molar ratio of nickel element to nitrogen element of 1: 4-1: 12, and roasting at 300-550 DEG C in a roastingatmosphere for 1-6 hours to synthesize the hydrogenation catalyst. The hydrogenation catalyst is used in the reaction process of preparing furfuryl alcohol through furfural liquid phase hydrogenation,and the hydrogenation catalyst has high catalytic activity and catalytic selectivity. The hydrogenation catalyst contains no chromium, and has the advantages of simple preparation method, wide raw material source and the like.

Description

technical field [0001] The invention belongs to the technical field of furfuryl alcohol production, and in particular relates to a method for preparing furfuryl alcohol by liquid-phase catalytic hydrogenation of furfural. Background technique [0002] Furfuryl alcohol is an important organic chemical raw material, which can be used to prepare levulinic acid and furan resins with various properties. As a selective solvent, dispersant and lubricant, it is often used in furfuryl alcohol resin, sediment aldehyde resin and phenolic resin, etc. Also a good solvent for varnishes, pigments and rocket fuel. At the same time, plasticizers can be produced, and its cold resistance is better than esters of butanol and octanol. It can also be used in the synthesis of dyes, pharmaceutical intermediates, chemical intermediates and synthesis of pyridine. In addition, it can also be used in synthetic fibers, rubber, pesticides and foundry industries. [0003] At present, the main producti...
