DOP), the solubility is very small, but as the temperature increases, the solubility increases sharply (100 Da43g/100g DOP). Low toxicity.

Storage method

Synthesis method

Combine resorcinol and lye Pour into the reaction kettle according to the proportion and stir to dissolve. Control temperature1820℃, while stirring, slowly add benzoyl chloride. During the dropwise addition of benzoyl chloride, maintain 1820℃ remains unchanged. After the dropwise addition is completed, the temperature is still maintained and the reaction is continued to stir untilpHCan be output when the value remains unchanged material. After filtering, washing with hot water until neutral and drying, the crude product is obtained. Then use five times the price of the crude product(Quality)Toluene is dissolved at reflux temperature, decolorized with activated carbon, filtered, cooled, crystallized, filtered, and dried to obtain the finished product.


This product is used for cellulose plastics and Light stabilizer and antioxidant for PVC. Suitable for transparent products, the dosage is generally resin1.0%2.0%(Quality).

�Light stabilizer and antioxidant for ethylene. Suitable for transparent products, the dosage is generally resin1.0%2.0%(Quality).
