Embodiment
[0040] 3.99 moles of white phosphorus (P 4 ) / hour of the stream was continuously fed into the evaporator and evaporated at 770K at atmospheric pressure. The resulting stream was fed into the chamber of a reactor with a volume of 7800 mL. 12 mol / h (as O 2 ) of continuous oxygen flow into the same reactor. A stream of 1105 g / h of the slurry already obtained in earlier experiments was fed into the reactor through a separate hole at the top of the reactor. The slurry consisted of 24 wt% higher solids P oxides and suboxides, 1% P 4 and 75% of P 4 o 6 composition. The slurry was held at 303K prior to addition. These reaction parameters correspond to a residence time in the reactor of 11 seconds. The reaction chamber was observed to reach a temperature of 1780K without external cooling. The reaction product leaving the reaction chamber at its outlet is then contacted with an earlier condensed liquid reaction product stream obtained from a previous experiment carried out unde...
