| 应用领域 | Uses: Used as a flame retardant、plasticizer、lubricant、additive to gasoline and hydraulic fluids、and intermediate for pharmaceuticals. Also used in coatings and adhesives、in adhesives for air filter media、as a heat exchange medium、a waterproofing agent、an extraction solvent、and in solvent mixtures for resins、[ACGIH]、As plasticizer in lacquers and varnishes.、... Flame retardent and plasticizer、in hot extrusion molding and bulk forming of plasticized polyvinyl chloride、in coatings and adhesives、as a gasoline additive to control pre-ignition、in hydraulic fluids、a synthetic lubricant、as a water proofing agent、as a component of adhesives for air filter media、an intermediate in the synthesis of pharmaceuticals、and in a solvent mixture for various resins.、As additive to extreme pressure lubricants、as a non-flammable fluid in hydraulic systems、as plasticizer in lacquers and varnishes、as plasticizer in vinyl plastics manufacture、as flame retardant、as lead scavenger in gasoline、and as solvent for nitrocellulose、in cellulosic molding compositions.、Aryl phosphates such as tricresyl phosphate ... or cresyl diphenyl phosphates ... when added in small percentages to the gasoline、combat misfires.、Aryl phosphates、Tricresyl phosphate (ortho-、meta- and para-isomers) is used in flexible PVC、cellulose nitrate、ethylcellulose coatings、and various rubbers. Typical applications are vinyl tarpaulins、mine conveyer belts、air ducts、cable insulation、and vinyl films ... usually used in blends with phthalates.、Methods of Manufacturing: Prepared from cresol and phosphorus oxychloride、phosphoric acid、or phosphorus pentachloride. The grades of cresol commonly used are the isomeric (o-、m-、p-)、and meta-para mixtures fom coal tar and cresylic acid from petroleum. Purification of the product is based on the intended use、the commercial product is generally obtained as a mixture.
