CAS: 29385-43-1 136-85-6; 29385-43-1
MF: C7H7N3 MW: 133.15
2 Appearance
White granules or powder, can be processed into big flakes, small pieces of granular, columnar, fine granule, powder
3 Basic Uses Edit
This product is mainly used for metal (such as silver, copper, lead, nickel, zinc, etc.) rust and corrosion inhibitors, are widely used in anti-rust oil (fat) products in copper and copper alloys used for vapor phase corrosion agent, lubricant additives, circulating water treatment agent, automobile antifreeze. This product is also available with a variety of scale inhibitors, biocide used in conjunction with, especially for closed loop cooling water system corrosion and very good results.
4 Basic characteristics
Pure strains of white granules or powder 4 – a mixture of methyl benzene Benzotriazole melting point 80-86 ℃, insoluble in water, soluble in alcohol, benzene, toluene, chloroform – methyl benzene Benzotriazole and 5 other organic solvents, soluble in dilute alkali.
5 Production
① In the reactor, the 3,4-diaminotoluene placed in water and dissolved by heating;
The step ① to ② into a solution of 3,4-diaminotoluene was added sodium nitrite reaction;
③ ② step into the solution is cooled;
In step ③ ④ sulfuric acid was added dropwise into the solution, a large number of crystal formation;
The mixture obtained in step ④ ⑤ deprotection liquid treatment;
Proceeds will step ⑤ ⑥ crystal heating, dehydration;
Step ⑥ ⑦ The resultant crystal was then distilled to produce the 5 – methyl-benzo triazole; production method of the present invention are 3,4-diaminotoluene as a raw material, through pressure synthesis, acidification, dehydration, distillation , Preparation of 5 – methyl benzene Benzotriazole the process is simple, easy to control the manufacturing process, high yield, high purity, low production cost, easy to organize industrial production.
