Abstract

Se realiza disolviendo o suspendiendo en un disolvente neutro o ácido, acuoso u orgánico, los compuestos de fórmula III a temperaturas entre 0ºC y 150ºC, preferentemente entre 20 y 70ºC, agregando 10-3 hasta 10-1 moles de quinona, referido a la cantidad molar del compuesto III, mezclando la solución de reacción intensamente con oxígeno alimentado, normalmente oxígeno puro o aire, y agregando en el transcurso de la reacción bien 1 hasta 20 moles-% de nitratos o nitritos o dosificando en total uno hasta 20 moles-% de óxidos de nitrógeno. La dosificación se puede realizar bien con la corriente de oxígeno o desde un dispositivo de dosificación independiente. Para alcanzar una alta velocidad de reacción es necesaria una mezcla intensa entre el gas y el líquido. también es posible trabajar bajo presión.
