Title: Preparation of triarylphosphates
IPC: C07F9/12
Filed: 1960-10-10
Abstract: A process for making a triaryl phosphate comprises reacting at elevated temperatures phosphorous oxychloride and a phenol in the presence of a distillation residue remaining after distilling the reaction product derived from a reaction mixture containing said phenol, phosphorus oxychloride and a metal chloride catalyst or in place of said catalyst said distillation residue.  Suitable catalysts include aluminium, magnesium and zinc chlorides which may be formed in situ from the metal or an oxide and POC13. The phenol may be used in 2-10% stoichiometric excess.  The temperature may be from 40 to 130 DEG C. but may be raised at a later stage, e.g. up to 200 DEG C. to complete the reaction.  Preferably the distillation is carried out so as to leave in the residue about 65-85% of triaryl phosphate which is returned to the reactor along with the catalyst.  Fresh catalyst may be added to make up losses.  Batchwise and continuous processes are described. Phosphates are prepared from various "cresylic acids" in examples.
