An organophosphate (sometimes abbreviated OP) is the general name for esters of phosphoric acid. Phosphates are probably the most pervasive organophosphorus compounds. Many of the most important biochemicals are organophosphates, including DNA and RNA as well as many cofactors that are essential for life. Organophosphates are also the basis of many insecticides, herbicides, and nerve gases. Organophosphates are widely used as solvents, plasticizers, and EP additives.
Triphenyl phosphate is the chemical compound with the formula OP(OC6H5)3. This colorless solid is the ester of phosphoric acid and phenol. It is used as a plasticizers and a fire retardant.
Triphenyl phosphate is prepared by the reaction of phosphorus oxychloride and phenol in the presence of a base:
POCl3 + 3 HOC6H5 → OP(OC6H5)3 + 3 HCl
Tricresyl phosphate, abbreviated TCP, is an organophosphate compound. It is a derived from cresol and phosphoric acid. This viscous liquid is colourless when pure, but commercial samples are typically yellow. It is nonflammable and virtually insoluble in water. Commercial tricresyl phosphate is a mixture of ortho, meta, and para-cresyl phosphates.
