phosphorus trichloride is reacted with oxygen or air in batch reactors. About 500 tons per month can be produced in 3 reactors aggregating to 34 M3 volume. In a continuous process with a radical change inreactor design the reacting volume was only 0.5 M3 and it is possible to produce 700 tons per month. The productivity goes up by a factor of 95. It also results in only 5% excess oxygen consumption compared about 15-25% excess by batch process.
