Embodiment 1

[0017] Preparation of nickel-loaded carbon nitride material:

[0018] Disperse 500mg of carbon nitride into 8ml of distilled water, add an aqueous solution containing 70mg of potassium nickelous chloride, stir at 80°C for 1h, then slowly add sodium borohydride solution (NaBH 4 / Pd molar ratio is 3:1), stirred at room temperature for 4h, filtered, washed with distilled water, and vacuum dried at 80°C to obtain a carbon nitride material loaded with 5% nickel.

[0019] Catalytic furfural prepares the method for furfuryl alcohol:

[0020] Accurately weigh 200mg of furfural and 25mg of 5% nickel-loaded carbon nitride material (10% nitrogen content) into the lining of the autoclave, and add 3ml of water. After sealing the stainless steel autoclave, it was ventilated with hydrogen for 3 times, and then flushed with 1MPa hydrogen at room temperature. Preheat the oil bath to the required temperature, put it into the autoclave, react at 120°C for 6h, stop the reaction, and cool to roo...

Embodiment 2~10

[0023] The difference from Example 1 lies in the reaction temperature, hydrogen pressure, nickel loading and nitrogen content of the carbon nitride material. The results are shown in Table 1.

Abstract

The invention discloses a method for preparing furfuryl alcohol by catalyzing furfural, comprising the following steps: putting the furfural and a nickel-loaded carbon nitride material in a reaction device, adding distilled water, introducing hydrogen, and reacting for 4-8h under 80-140 DEG C; the load quantity of nickel is 3 percent-10 percent; the pressure of the hydrogen is 0.5-2MPa; the mass ratio of the furfural to the nickel-loaded carbon nitride material is (5-10):1. The nickel-loaded carbon nitride material can effectively catalyze the furfural to prepare the furfuryl alcohol; the reaction conditions are mild; water is used as a solvent and the reaction is environment-friendly, and a higher furfuryl alcohol productive rate is achieved.

Description

technical field [0001] The invention relates to a method for preparing furfuryl alcohol by catalyzing furfural. Background technique [0002] As an important fine chemical intermediate and raw material, furfuryl alcohol is widely used in various fields such as medicine, food, beverage, pesticide and dyestuff. Furfuryl alcohol can be prepared from furfural. However, in the prior art, in order to obtain high-yield furfuryl alcohol, it is generally necessary to use toxic organic solvents, which does not conform to the concept of sustainable development. Therefore, it is necessary to develop a green and environmentally friendly preparation method. Contents of the invention [0003] The present invention provides a method for preparing furfuryl alcohol by catalyzing furfural in order to overcome the above-mentioned defects in the prior art. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: ...
