| 应用领域 | Uses: Used for organic synthesis、in dyes、in fragrances、flavor compounds、and perfumery、in solvents for cellulose lacquers、in the manufacture of hexachlorophene、benzophenone、and pharmaceuticals、[HSDB] Used in fragrances、dyes、polyesters、and jet fuels、[Ullmann]、Diphenylmethane is used in the fragrance industry both as a fixative and in scenting soaps. It can serve as a synergist for pyrethrin in pesticides and insecticides. Diphenylmethane is recommended as a plasticizer to improve the dyeing properties、as a solvent for dyes、and as a dye carrier for printing with disperse dyes. The addition of diphenylmethane to saturated、linear polyesters improves their thermal stability、and its addition to jet fuels increases their stability and lubricating properties.、Organic synthesis、As a component of solvents for cellulose lacquers.、In the manufacturing of hexachlorophene.、Use Classification: Fragrance Ingredients、Cosmetics -> Solvent、Industry Uses: Intermediate、Consumer Uses: Heat transferring agent、Methods of Manufacturing: The Friedel-Craft reaction of benzyl chloride with benzene in the presence of aluminum chloride is an important method for production of diphenylmethane ... Other known catalysts of this process are elemental aluminum、iron(III) chloride、antimony pentachloride、zinc chloride-hydrogen chloride and boron fluoride dihydrate. When sulfuric acid is used as a condensation agent diphenylmethane yields are 83% and with polyphosphoric acid yields are over 90%. Condensation of benzene with formaldehyde in presence of 85% sulfuric acid yields 79% diphenylmethane.、Prepared from methylene chloride and benzene with aluminum chloride as catalyst.、Formulations、Preparations: Commercial diphenylmethane should be at least 97% pure. It must be free of halogens and have a minimum melting point of 24 °C.、Consumption Patterns: Use in fragrances in the USA amounts to less than 4000 lb、yr. Concentration in final product (%): soap: usual 0.03、max 0.2、detergent: usual 0.005、max 0.05、creams、lotions: usual 0.01、max 0.1、perfume: usual 0.05、max 0.8.、U.S. Production: 2023: 58、140 lb、2022: 53、270 lb、2021: 51、650 lb、2020: 47、020 lb、(1977) PROBABLY GREATER THAN 2.72X10+6 GRAMS、(1979) PROBABLY GREATER THAN 2.72X10+6 GRAMS、Production volumes for non-confidential chemicals reported under the Inventory Update Rule.[Table#5191]、Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: Phenol、Benzene、1、1'-methylenebis-. Aggregated National Production Volume: 1 to < 10 million pounds.、General Manufacturing Information: All Other Chemical Product and Preparation Manufacturing、1'-methylenebis-: ACTIVE |
