Abstract

The invention relates to a process of preparing tetrahydrofurfuryl alcohol with furfuryl alcohol catalytic hydrogenation, under condition of furfuryl alcohol catalytic hydrogenation and existence of loading NiB and NiCoB amorphous alloy catalyst prepared with metallic revulsion chemical plating method, making furfuryl alcohol contact with alcohol in autoclave for reaction. The catalyst is the amorphous alloy with inorganic oxidate loading effective amount of active component NiB or NiCoB, the mass of the said effective active component NiB or NiCoB is 20% of the catalyst mass. The invention is characterized by the good catalytic activity of the furfuryl alcohol hydrogenation, high conversion rate of furfuryl alcohol, good selectivity of tetrahydrofurfuryl alcohol, temperate reacting condition, simple process, easy for industrial production and no pollution to environment.

Description

technical field [0001] The invention relates to a catalytic hydrogenation reaction, in particular to a process for preparing tetrahydrofurfuryl alcohol by hydrogenation of furfuryl alcohol, using a supported NiB and NiCoB amorphous alloy catalyst prepared by a metal-induced electroless plating method to prepare tetrahydrofurfuryl alcohol in the hydrogenation reaction of furfuryl alcohol application technology in. Background technique [0002] Tetrahydrofurfuryl alcohol, also known as tetrahydrofuran-2-methanol, is an important organic solvent and fine chemical raw material. It is a good flux solvent for electronic chemicals and fluxes, a good solvent for resins, paints, and oils, and it is also a raw material for making dihydrofuran, tetrahydrofuran, lysine, and long-acting vitamin B1. It can also be used to make Polyamide plastic, used as lubricating oil, dispersant and decolorizing and deodorizing agent in printing and dyeing. [0003] At present, the catalyst used for t...
