Method and device for producing phosphorus

A method for producing phosphorus, the method comprising:

• a reduction reaction for forming gaseous phosphorus (g) by bringing phosphorus oxide generated by heating a liquid phosphoric acid compound into contact with a carbon material, and
• a condensation of the gaseous phosphorus (g) into liquid phosphorus (L),
• wherein the reduction reaction of the phosphorus oxide and the condensation of the gaseous phosphorus (g) are conducted by a flow reaction with a nonoxidizing gas flow,
• wherein the reduction reaction of the phosphorus oxide is conducted in a carbon material-packed bed, and
• the condensation of the gaseous phosphorus (g) is substantially conducted in a condensation accelerator-packed bed which is disposed downstream of the carbon material-packed bed and in contact with the carbon material-packed bed.
