| 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 Reference(s) | The Journal of Organic Chemistry, 23, p. 1350, 1958 DOI: 10.1021/jo01103a031

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%. |
