Product Applications

Widely used in the thermal processing of polypropylene, polyethylene, polyoxymethylene, ABS resin, etc., which can prolong the service life of plastic products; This product is a kind of non-discoloration, non-pollution, heat-resistant oxygen aging, heat-resistant water extraction, no sunset glow volatile antioxidant. Can be used for polypropylene, polyethylene, polyformaldehyde,..

Production method

This product is obtained by transesterification reaction between pentaerythritol and β-(3,5-di-tert-butyl-4-hydroxyphenyl) methyl propionate under the catalysis of sodium methoxide at 100-140 ℃. Dipolypentaerythritol and potassium tert-butoxide can also be used as catalysts, DMF as solvent, and the above raw materials can also be prepared by reaction, with a yield of 95.8.
