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

Storage method

Packaged in paper barrels lined with plastic bags . Store and transport according to general chemical regulations.

Synthesis method

Combine resorcinol and lye Pour into the reaction kettle according to the proportion and stir to dissolve. Control temperature18～20℃, while stirring, slowly add benzoyl chloride. During the dropwise addition of benzoyl chloride, maintain 18～20℃ 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.

Purpose

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).
