4-Chlorobenzonitrile Chemical Properties,Uses,Production

Chemical Properties

4-Chlorobenzonitrile [623-03-0], 4- chloro-1-cyanobenzene, Cl – C6H4 – CN, Mr 137.6, mp 97℃, forms colorless crystals that can be sublimed. The compound is steam volatile, readily soluble in organic solvents, and only sparingly soluble in water. 4-Chlorobenzonitrile is produced industrially by the ammoxidation of 4-chlorotoluene. It is used in the synthesis of a red pigment for plastics.

Uses

4-Chlorobenzonitrile is used to prepare a red pigment for plastics. It is also used in the preparation of amides in organic synthesis. Further, it is used as an intermediate of dye and active pharmaceutical ingredients.

Definition

ChEBI: 4-Chlorobenzonitrile is a member of benzenes and a nitrile.

Synthesis

224 grams of V2O5 was added to a solution consisting of 490 ml of water 468 grams of oxalic acid at a temperature of 80 to 90C, stirred thoroughly, and reacted to obtain a vanadium oxalate solution.

1250 g of SiO2 silica sol at a weight percent concentration of 40% SiO2 was slowly added to the above solution under stirring, and then a solution comprising 864 g of Cr(NO3)3-9H2O, 12.4 g of KNO3 and 500 ml of water, 76.4 g of H3BO3, 85.1 g of 85% phosphoric acid and 500 ml of water and 43.5 g of (NH4)6Mo7O24-4H2O and 100 ml of water were composed of a solution, stirred, heated and evaporated to a solid content of 40% by weight to obtain a viscous slurry.

After the above slurry was formed by spray drying, the catalyst precursor was pre-roasted at 300C for 2 hrs, and then roasted at 650C for 5 hrs to obtain a catalyst composed of atomic ratio: V1.00Cr0.9B0.50P0.30Mo0.10K0.05/SiO2, and the catalyst main loading weight ratio was 50/50.

Property Evaluation of Catalyst Processes Conditions: p-chlorotoluene: ammonia: air = 1:4:25 (molar), catalyst weight loading (WWH) 0.05 h-1, reaction temperature 420 , reaction pressure 0.01 MPa.

Results: p-chlorotoluene conversion 99.6% p-chlorobenzonitrile selectivity 91.5 %, p-chlorobenzonitrile conversion 99.6% p-chlorobenzonitrile selectivity 91.5% p-chlorobenzonitrile conversion 99.6% p-chlorobenzonitrile conversion. nbsp;91.5% p-chlorobenzonitrile yield 91.1%.
