PROCESS FOR REDUCING THE REACTIVITY AND IMPROVING THE FLOW BEHAVIOUR OF PHOSPHORUS PENTOXIDE |
| 摘要 |
<p>PROCESS FOR REDUCING THE REACTIVITY AND IMPROVING THE FLOW BEHAVIOUR Of PHOSPHORUS PENTOXIDE The reactivity of phosphorus pentoxide is reduced and its flow behaviour improved. To this end, phosphorus pentoxide in the form of its hexagonal modification is annealed over a period of 0.5 to 8 hours at temperatures of 200 to 390.degree.C.</p> |
