Antioxidant 1010 is a white powder, odorless and tasteless. The melting point is 110℃-125℃ and its properties are stable. Easily soluble in solvents such as benzene, acetone and ester, insoluble in water and slightly soluble in ethanol. This product is pollution-free, has good heat and water resistance, and good compatibility. Used together with antioxidants AT-168, DLTDP, etc., it can exert a synergistic effect and improve the oxidation effect.
The production method of antioxidant 1010 is as follows:
From pentaerythritol and β-(3,5-di-tert-butyl-4-hydroxyphenyl ) Methyl propionate is catalyzed by sodium methoxide and undergoes a transesterification reaction at 100-140°C to obtain this product. Dimeric pentaerythritol and potassium tert-butoxide can also be used as catalysts and DMF as solvent. It can be prepared by reacting the above raw materials with a yield of 95.8%.
The functions and uses of antioxidant 1010 are as follows:
It is widely used in polyethylene, polypropylene, polyformaldehyde, ABS resin, PS resin, PVC, Among engineering plastics, rubber and petroleum products, it has excellent antioxidant properties for polypropylene and polyethylene. It can effectively extend the service life of products. Also used to prevent thermal and oxidative aging of greases and coatings.
When used together with the auxiliary antioxidant DLTDP and antioxidant 168 in polypropylene resin, it can significantly improve its thermal stability. It is currently one of the most excellent varieties of phenolic antioxidants.
