| | 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) Usage And Synthesis |
| Chemical Properties | Pure product is white powder, slightly yellowish pink color when exposed to air for a long time. Slightly phenolic odor. Easily soluble in benzene, acetone and other organic solvents, insoluble in water, solubility in rubber is higher than 2%. | | Uses | LOWINOX® 22M46 stabilizer is a non-discoloring antioxidant based on a sterically hindered alkylated bis-phenol. | | Uses | It may be incorporated into the bromobutyl rubber(BIIR) matrix to enhance the overall thermo-reversibility of dicyclopentadiene dicarboxylic acid (DCPDCA) cross-linked BIIR. It may also be used as an antioxidant which shows a higher oxidation stability in distilled biodiesel. | | Definition | ChEBI: 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) is a diarylmethane. | | General Description | 2,2′-Methylenebis(6-tert-butyl-4-methylphenol) is a phenolic antioxidant commonly used in increasing the oxidation stability in rubber and plastic industries. | | Flammability and Explosibility | Not classified | | Industrial uses | 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) is used in the following products: adhesives and sealants, lubricants and greases, fuels, hydraulic fluids and metal working fluids. | | Source | 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) is a natural product found in Streptomyces and Aspergillus fumigatus with data available. | | Properties and Applications |
