Abstract
Según el procedimiento de la presente invención se hacen reaccionar en una reacción de dos ó de varias etapas compuestos hidroxi aromáticos con oxihaluros de fósforo, pentahaluros de fósforo, dihaluros de monoéster de ácido fosfórico y monohaluros de diésteres de ácido fosfórico, en presencia de soluciones acuosas de hidróxido de metal y cantidades suficientes de disolventes orgánicos a triésteres de ácido fosfórico. Preferentemente se emplea el procedimiento de la presente invención para la reacción de compuestos hidroxi aromáticos con oxicloruro de fósforo en presencia del lejía alcalina acuosa y disolventes orgánicos, no miscibles con agua. El valor pH se mantiene en el transcurso de la reacción preferentemente en un pH de 7,5 hasta 13,5. De ésta manera se evitan, contrario a los procedimientos usuales en la práctica, los problemas de corrosión originados por el cloruro de hidrógeno libre.
