Tritolyl phosphate, mixture of isomers

Description

CAS: 1330-78-5 | C₂₁H₂₁O₄P

Tritolyl phosphate, mixture of isomers is used as plasticizer in nitrocellulose, acrylate lacquers, and in polyvinyl chloride. It is a fire retardant for plastics and rubbers. air filter medium, solvent mixtures and heat exchange medium. It is employed as a gasoline additive and as a lead scavenger for tetraethyllead. Further, it acts as a solvent for extraction, especially for nitrocellulose and polymers. In addition to this, it is used for the waterproofing of materials, an antiwear and extreme pressure additive in lubricants and hydraulic fluids.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
