Abstract

Procedimiento para la preparación continua de fosfina pura por reacción de fósforo amarillo elemental con solución acuosa concentrada de un hidróxido de metal alcalino con exclusión de oxígeno en presencia de alcohol, a temperaturas entre 44 y 90ºC, incorporándose por separado entre sí en una zona de reacción el fósforo y la solución de hidróxido de metal alcalino, caracterizado porque la reacción se lleva a cabo en dos etapas de reacción separadas, haciéndose reaccionar en la primera etapa de reacción la solución de hidróxido de metal alcalino y el fósforo en una proporción molar de 0,7 a 0,9 con agitación, recogiéndose la fosfina gaseosa pura resultante en tal caso, introduciéndose simultáneamente la fase líquida, que contiene fósforo no reaccionado, en la segunda etapa de reacción, y porque allí se hace reaccionar el fósforo restante, los productos de reacción gaseosos resultantes en tal caso son recogidos por separado respecto de los de la primera etapa de reacción y son aprovechados.
