Phenylacetonitrile
Chemically colorless liquid.
It smells good.
Insoluble in water, mixed with ethanol and ethyl ether.
It is used mainly for medicinal, pesticide, dyes and spices intermediates
USES as gas chromatographic fixation fluid, also used in the separation and organic synthesis of gas hydrocarbon and halogenated hydrocarbons
The use of phenylacetonitrile is a fungicide, phenylein, the insecticide, thiophosphorus, the rice fuses, and the rat, the rat, and the agent of the ketone.
Used to produce medicine, pesticide intermediates phenylacetic acid, phenethylamine, diphenyl acetonitrile, alpha phenyl ethyl amide, benzene acetic acid ethyl ester, beta phenylethyl alcohol, benzene acetaldehyde and ethyl phenyl benzoate, alpha chlorinated benzene acetic acid ethyl ester, etc., used in the manufacture of phoxim, rice powder, such as penicillin, phenobarbital.
The production methods are reacted by the reaction of benzyl chloride and sodium cyanide.
The reaction was carried out in alcoholic solvents and was catalyst for dimethylamine.
Reaction temperature is 80-100 ℃.
After the reaction was made of benzene acetonitrile, the product was finished by decompression distillation.
Pure products can be 99% purity and yield about 90%.
Raw material consumption quota: (96%) 1270kg/t, sodium cyanate 490kg/t, ethanol (95%) 544kg/t, dimethylamine (30%) 17kg/t.
The production method is made by condensation of benzyl chloride and sodium cyanide.
Generally using ethanol as solvent, under the heating reflux, also can use water as medium, and phase transfer catalyst, reaction temperature 80 ~ 100 ℃, after the reaction and the solvent separation, then through distillation to finished products.
