1. Performance and use:
Triethyl Phosphate (TEP) is a colorless, high-boiling liquid and containing 17 wt % phosphorus; mild odor. Very stable at ordinary temperatures, compatible with many gums and resins, soluble in most organic solvents, miscible with water. When mixed with water is quite stable at room temperature, but at elevated temperatures it hydrolyzes slowly.
TEP is useful as a solvent in many applications, as a plasticizer for tough, fire-resistant plastics, and as an agricultural chemical as an intermediate in preparing tetraethyl pyrophosphate (TEPP).
Triethyl phosphate is use as a flame retardant in the manufacture of polyisocyanurate (PIR) and polyurethane (PUR) foam insulation and thermoset plastic products.
Triethyl phosphate is also used as a viscosity reducer in plastic resins.
Triethyl phosphate is use as a catalyst, solvent or intermediate in the production of pesticides, pharmaceuticals, lacquers and other products.
Triethyl phosphate is use as ethylating agent.
Triethyl phosphate is use as a formation of polyesters which are used as insecticides.
