Tolytriazole Sodium Salt TTAS price Sodium Tolyltriazole

The preparation method of sodium salt of methylbenzotriazole (TTA.Na/TTAS) cas:64665-57-2 is relatively simple, usually obtained through acid-base neutralization reaction of methylbenzotriazole. Firstly, dissolve methylbenzotriazole in a small amount of alkaline solution, then gradually add acid to neutralize it and precipitate the produced sodium salt. Finally, the pure product methylbenzotriazole sodium salt is obtained through filtration, washing, and drying Method 2 for preparing sodium salt of methylbenzotriazole: After adding water and methylbenzotriazole in sequence to the reaction bottle, start the stirring reaction device and keep it at room temperature by adding sodium hydroxide in batches. Stir the reaction at room temperature, add activated carbon, heat up to 50-60 ° C for decolorization, filter while hot, and let the filtrate cool to room temperature to obtain the solution of sodium salt of methylbenzotriazole.
