| 应用领域 | Uses: Used as flame retardant、[HSDB] Used in isomeric mixture known as Tricresyl phosphate (CAS # 1330-78-5)、Plasticizer in vinyl plastics manufacture、flame-retardant、solvent for nitrocellulose、in cellulosic molding compositions、as additive to extreme pressure lubricants、non-flammable fluid in hydraulic systems、as lead scavenger in gasoline、to sterilize certain surgical instruments、Isomeric mixture、Aryl phosphates such as tricresyl phosphate ... when added in small percentages to the gasoline、combat misfires.、Aryl phosphates、The commercial tricresyl phosphate product is essentially a meta、para-isomer mixture. Tricresyl phosphate 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 from 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. A "refined grade" of tricresyl phosphate is prepared by vacuum distillation、or alternatively by washing with 2% sodium hydroxide and water ... .、Tricresyl phosphate、Consumption Patterns: 55% AS A FLAME RETARDANT IN FUNCTIONAL FLUIDS AND LUBRICANTS、30% AS A FLAME RETARDANT PLASTICIZER FOR POLYVINYL CHLORIDE、CELLULOSE ESTERS、AND NITRILE RUBBER COMPOUNDS、5% AS AN AIR FILTER ADHESIVE MEDIUM、10% IN MISC APPLICATIONS (1974)、U.S. Production: (1972) 2.28X10+10 GRAMS、U.S. Imports: (1972) NEGLIGIBLE、(1975) 6.82X10+7 GRAMS (PRINCPL CUSTMS DISTS)、General Manufacturing Information: Phosphoric acid、tris(4-methylphenyl) ester: ACTIVE、TRICRESYL PHOSPHATE SHOULD NOT BE USED IN PLASTIC ARTICLES WHICH ARE LIKELY TO COME INTO CONTACT WITH FOODSTUFFS OR CLOTHING.、ISOMERIC MIXT、A tricresyl phosphate prepared from m- or p-cresol has the same properties as the technical product、but the cost of separating and purifying these isomers is prohibitive.、Isomeric mixt、...
