Solvent-free microwave synthesis of trialkylphosphates

Trialkylphosphates are synthesized from alcohols by reaction with reactive phosphorus oxychloride under microwave irradiations and classical heating. Effects of these irradiations on the nature of the products and on the yield are studied. The compounds were characterized by their spectroscopic data and elemental analysis. The obtained results show that the products of these reactions are essentially trialkylphosphates and alkylphosphoric acids. They always show as the nature of the formed products and the yields in trialkylphosphates are comparable to those obtained in the classical conditions of heating. The speed of the reaction was increased by a factor from 40 to 120.

NMR study of the action of phophorus pentoxide on p-(1,1,3,3-tetramethylbutyl) phenol

The reaction between P2O5 and p-(1,1,3,3'-tetramethylbutyl)phenol was investigated through 31P-NMR. The considered kinetic model showed that only time and, to a lesser extent, the temperature of the reaction, seem to influence the yield. The reactant mole ratio exhibits no effect upon the MOPPA:DOPPA ratio. Attempts based on a 2 3 factorial experiment design allowed to confirm these results. The tripyroesters were identified as being the longest intermediates detected by NMR. In the reaction mixture no traces of phosphoric triester (TOPPA) were detected.
