Useful:

• Uses: Tricresyl phosphate (TCP) is used as a solvent for nitrocellulose esters and numerous natural resins. It is a plasticizer for chlorinated rubber, vinyl plastics, polystyrene and polyacrylic and polymethacrylic esters. Tricresyl phosphate also acts as a binder for resins and nitrocellulose to improve toughness, elasticity and polishing properties of coatings. Alone or associated with hydrocarbons, it is used as an antiwear and antifriction additive in numerous synthetic lubricants, incorrectly termed “oils” by reason of their appearance. It is also employed as a hydraulic fluid. When incorporated in gasoline, tricresyl phosphate counteracts the harmful effects of lead deposits. In addition, it is an excellent fire retardant in many industries. Usually used as a mediator in the preparation of uranium-sensitive electrode based on membrane containing uranium di-(4-octylphenyl)phosphate as sensor. Tricresyl Phosphate is used as plasticizer in vinyl plastics manufacture, as flame-retardant, solvent for nitrocellulose, in cellulosic molding compositions, as additive to extreme pressure lubricants, as a nonflammable fluid in hydraulic systems, as lead scavenger in gasoline: Yust, Bame, US 2889212 (1959 to Shell); to sterilize certain surgical instruments. Tricresyl phosphate is used as plasticizer in vinyl plastics manufacturing; in spectacle frames; flame-retardant; solvent for nitrocellulose; in cellulose-molding compositions; additive to extreme-pressure lubricants; nonflammable fluid in hydraulic systems; lead scavenger in gasoline; used to sterilize certain surgical instruments; in polystyrene; in waterproofing; in common organic solvents and thinners; in linseed oil; emulsifying agent in cosmetics; in china wood oil; in castor oil.
