Results and discussion
- Results:
- Citation: For many kinds of red phosphorus "products" (including various size distributions), storage is not possible. Each product is immediately packed under nitrogen in the customer's container.
Red phosphorus is packed in polyethylene bags under nitrogen, and these are packed in steel open-topped drums with lids. For tonnage quantities of red phosphorus, stainless steel containers are used. The following regulations apply: - Transformation products:

Any other information on results incl. tables
Red phosphorus should be stored and handled under an inert gas atmosphere because itis thermodynamically unstable in the presence of water and oxygen. Otherwise red phosphorus will very slowly undergo disproportionation and oxidation reactions.
These reactions lead to a mixture of phosphorus oxyacids and traces of hydrogen and/or phosphine according to the qualitative description below.
Px + H2O + O2 ---> H3PO4 + H3PO3 + H3PO2 + H2 + PH3
The known acidic phosphorus-containing reaction products are phosphoric acid (H3PO4), phosphorous acid (H3PO3), and hypophosphorous acid (H3PO2) depending on the amount of oxygen present.
Applicant's summary and conclusion
- Conclusions:
- Red phosphorus should be stored and handled under inert gas.
- Executive summary:
Red phosphorus should be stored and handled under an inert gas atmosphere. Usually it is packed in polyethylene bags under nitrogen, and these are packed in steel open-topped drums with lids. For tonnage quantities of red phosphorus, stainless steel containers covered with nitrogen are used.
