Pure white powder or powder, is a mixture of 4-methyl benzotriazole and 5-methyl benzotriazole, melting point 80-86 ° C, insoluble in water, soluble in alcohol, benzene, toluene, chloroform And other organic solvents, soluble in dilute alkali solution. Storage: This product is easy to absorb moisture should be stored in a ventilated, dry place, not mixed with food and seeds
Tolyltriazole (TTA) can be used as corrosion inhibitor of copper and copper alloy, it also has corrosion inhibition for black metals. This product is absorbed on metal surface to form a thin membrane to protect copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. When used together with MBT, the effect is better.
Tolyltriazole (TTA) specifications
pH Value: 5.0-6.0
Tolyltriazole (TTA) Production Process
① in the reactor, 3,4-diaminotoluene placed in pure water, heating dissolved;
(2) To the solution prepared in step (1), to join sodium tris (4)
③ the solution of step ② is cooled;
④ in the ③ solution into the solution by adding sulfuric acid, a large number of crystal formation;
(5) subjecting the resulting mixture to a dewatering treatment;
⑥ will step ⑤ the resulting crystal heating, dehydration;
(3) The obtained crystal is distilled to produce the 5-methylbenzotriazole; the production method of the present invention uses 3,4-diaminotoluene as a raw material, and is produced by medium pressure synthesis, acidification, dehydration and distillation The preparation process of 5-methylbenzotriazole is simple, the preparation process is easy to control, the yield is high, the purity is high, the production cost is low, and it is easy to organize the industrial production.
