Specs:99.5% Product Description: Antioxidant YD-702 Chemical Name: 4，4′Methylene bis(2,6－di-tert-butylphenol) Molecular formula C29H44O2 Molecular Weight 424.66 Introduction: The product takes on an appearance of white or canary crystallized powder. It is soluble in organic solvents like ethanol, acetate butyrin, gasoline, toluene, dichloromethane, slightly soluble in methanol and ethanol, and insoluble in water and 10% sodium hydroxide solution. Its color gradually gets darker when exposed to air for a long time. Melting point: 149—154℃ stacking specific gravity: 0.5－0.6 g/cm3. With stable chemical properties, the product is combustible but not flammable, and has little odor under normal temperature. Physical Properties: Appearance: White or canary crystallized powder Assay: ≥98% Melting Range: 149～154℃ Ash: ≤0.1% Volatiles: ≤0. 3% Applications: The product is an important phenolic antioxidant, which is mainly used for plastics, natural and synthetic rubber, and usually used as oils additives. With the excellent performance on high-temperature antioxidation, it finds many applications in oil products serving under high temperature like heat conduction oil, quench oil and special lubricant. Package: Net 25KGS/two-layer PE bag in carton/drum, or as required Storage: With stable chemical properties, no special requirements are needed for storage but protection from moisture and heat. |
