Benzoic acid nitrile;Benzonitrile;BN;Cyanobenzene;Phenyl cyanide
Molecular formula : C7H5N
MW : 103.12
CAS, DSC-47-0

nature : a transparent almond-flavored non-water-soluble liquid, organic nitriles toxic chemicals. Density 1.008 × 103kg/m3, TV & Entertain Licensing Authority ° C melting point, boiling point, 190.7 ° C, 123.5 ° C (13.33kPa), 69.2 ° C (1.33kPa.Conclusion), the freezing point TV & Entertain Licensing Authority ° C folding radio rate of 1.5289, solubility strong, with the general solvent immiscible. Micro dissolve in water, acetone, with ethanol, ethyl ether immiscibility. With strong refraction. Flammable, a flash point of 71 ° C.

Preparation : 1. France acid acid derived by ammoniation. Reminders by agents of alumina, the reaction temperature of 250 ° C to 350. 2. Ammoxidation in the presence of ammonia, toluene using air generated from oxidation. Toluene through chrome vanadium catalyst at 350 ° C gas ammonia oxidation reaction, and then distillation derived products. The consumption of raw materials fixed : toluene 2000 / t, ammonia 1200kg / t. There are other ways of aniline hydrochloride and nitrite diazotization, with cuprous cyanide; Benzamide with thionyl chloride reaction can be obtained Benzylintrile. These methods, cuprous cyanide copper sulfate and potassium cyanide can be derived role. For example, copper sulfate 60g, 50g potassium cyanide into water and 90ml cuprous cyanide solution, preheat to 60 ~ 70 ° C, under intense mixing batches to join 18.6g aniline, 50ml hydrochloric acid, sodium nitrite and bacterial system 125ml of cold diazonium salt solution, the reaction temperature does not exceed 60 ~ 70 ° C, isolated generated Benzylintrile bacterial yield 77%.

purposes : mainly used for the generation of benzene and other senior melamine coating intermediates, as well as synthetic pesticides, aliphatic amines, acid intermediates and serve as dicyanonaphthalene rubber, resin, polymer and paint solvents. Benzylintrile series derived intermediates is : Benzylamine, benzamide, Thio benzamide, halogenated imide, imine ester, Thio imine ester, amidoxime kai, and so on hydrazine.
