Description and Uses
Tricresyl Phosphate (TCP) is a mixture with a slightly pungent odor: of the three isomers, the normal and meta isomers are liquids, while the para isomer is a crystalline solid. TCP can be obtained by treating cresol with phosphorus oxychloride in the presence of an aluminum catalyst. It is used to recover phenol residues in gas plant wastewater and is also used as a plasticizer in the plastics industry. Plasticizers are substances used to increase the flexibility of plastic materials. By changing the amount of plasticizer added, the flexibility, hardness, water resistance and flammability of plastic materials can be changed over a wide range. Sometimes up to 50% TCP is added to polyvinyl chloride[1]. In addition, TCP is toxic to humans and can cause neuropathy, paralysis of the hands and feet, and/or death of humans and animals through ingestion, inhalation, and even absorption through the skin.
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.
