Tricresyl Phosphate CAS#1330-78-5
Improved Plastic Properties：TCP enhances the flexibility, hardness, and water resistance of plastic materials, particularly in PVC, improving their overall performance.
Efficient Phenol Recovery：TCP aids in the recovery of phenol residues from gas plant wastewater, contributing to waste management and environmental protection.
Versatile Industrial Use: Beyond plastics, TCP is widely used in lubricants, hydraulic systems, and as a solvent for nitrocellulose, showcasing its versatility.
Chemical Stability: TCP consists of three isomers, offering flexibility in its applications, with the para isomer being a solid and the others being liquids.
Tricresyl Phosphate (TCP) is a chemical mixture with a slightly pungent odor. It consists of three isomers: the normal and meta isomers are liquids, while the para isomer is a crystalline solid. TCP is produced by reacting cresol with phosphorus oxychloride using an aluminum catalyst. It is used to recover phenol residues from gas plant wastewater and as a plasticizer in the plastics industry. Plasticizers like TCP enhance the flexibility, hardness, water resistance, and flammability of plastic materials, with up to 50% TCP added to polyvinyl chloride (PVC). However, TCP is toxic to humans and animals, causing neuropathy, paralysis, and even death through ingestion, inhalation, or skin absorption.

Tricresyl Phosphate is utilized in the production of vinyl plastics as a plasticizer, flame retardant, and solvent for nitrocellulose. It is also employed in cellulosic molding compounds, as an additive in extreme pressure lubricants, and as a nonflammable fluid for hydraulic systems. Additionally, it serves as a lead scavenger in gasoline and is used to sterilize specific surgical instruments, as noted in Yust, Bame, US 2889212 (1959 to Shell).
