Abstract

The invention provides a method for preparing furfuryl alcohol from furfural and formic acid through transfer hydrogenation and relates to furfuryl alcohol. The method comprises steps as follows: a reactant furfural is added to an organic solvent, and a reactant solution is prepared; the reactant solution, anhydrous formic acid and a CuO-BaO catalyst are mixed and put in a reaction kettle, air isdischarged, and furfuryl alcohol is obtained after a heating reaction. Co-precipitated CuO-BaO is taken as the catalyst, formic acid is taken as a hydrogen donor, and furfuryl alcohol is prepared through formic acid decomposition for hydrogen production and catalytic reduction of furfural. The catalyst is high in activity, and the system is environmentally friendly; the overall reaction process issimple to operate, low in time consumption, low in cost and high in furfuryl alcohol yield, and has broad industrial application prospect.

Description

technical field [0001] The invention relates to furfuryl alcohol, in particular to a method for preparing furfuryl alcohol by using furfural formic acid transfer hydrogenation catalyzed by furfural non-noble metal. Background technique [0002] Furfuryl alcohol is an important fine chemical widely used in synthetic fiber, rubber, resin, spices, pharmaceutical and pesticide intermediates and other industries. The largest consumption is the manufacture of synthetic fiber and furan resin, accounting for 80% in my country. 90%, among which furfuryl alcohol resin can be made into a plasticizer with excellent cold resistance. [0003] Furfuryl alcohol is a selective hydrogenation product in which the hydrogenation reaction only occurs on the furfural carbonyl. Usually, the industrial production of furfuryl alcohol mainly uses Cu-Cr catalysts, which are highly toxic and cause serious environmental pollution. Current development directions are mainly focused on the development of c...
