Furfuryl alcohol
Chemically colorless liquid, which can turn brown or dark red when exposed to sunlight or air.
Has a bitter taste.
Can be mixed with water, but unstable in water, soluble in ethanol, ether, benzene and chloroform, not soluble in petroleum hydrocarbon.
It is a good solvent and rocket fuel for resin, varnish, pigment, and can be used in synthetic fiber, rubber, pesticide and casting industry
It is used as the raw material, antiseptic coating and good solvent of various kinds of furan resin
Use GB 2761-1997 rules for the use of spices for food.
Mainly used in the preparation of caramelized essence.
The FDA, § 175.105: provisions for the food additive (adhesive) directly.
The use of furfuryl alcohol is used for organic synthesis, and hydrolyzed acetyl propionic acid (acid) is the intermediate body of calcium glycine in the nutritional drug.
By furfuryl alcohol can produce all kinds of properties of furan resin (such as furfuryl alcohol resin, furan Ⅰ or furan resin Ⅱ type), furfuryl alcohol - urea-formaldehyde resin and phenolic resin, etc.;
A plasticizer made from furfuryl alcohol is superior to that of butyl, octanol, and furan resin, varnish, good solvents and rocket fuel.
It is also used in synthetic fibres, rubber, pesticides and foundry industries.
The product is flammable and poisonous.
The mice took the oral LD50 to 275mg/kg.
The production method is reduced by hydrogenation.
There are two processes of hydrogenation and hydrogenation.
Liquid phase hydrogenation method and high voltage and medium voltage method, high pressure method in 9.8 MPa above operation, the temperature control between 170-200 ℃, with chromium trioxide and copper oxide as catalyst, furfural and the molar ratio of hydrogen to sons, and the conversion between 95-100%, middle pressure method more at about 6.73 to 6.86 MPa, the temperature control is controlled in 160-170, also with chromium trioxide and lead oxide as catalyst, the product obtained in 66.5 to 79.84 kPa pressure distillation furfuryl alcohol, conversion rate is 80-90% in general.
Gas phase hydrogenation method under 0.1 0.39 MPa, the temperature control is controlled in 80-170 ℃, with nickel and chromium - copper catalyst.
The ratio of furfural to hydrogen is high and the cost is low.
Raw material consumption quota: furfural 1120kg/t, hydrogen 300m3 / t.
