  • Production of red phosphorus
    Patent number: 4526766
    Abstract: Red amorphous phosphorus is formed by thermal conversion of yellow phosphorus by a process wherein thermal conversion is effected while simultaneously the heat of conversion is permitted to effect evaporation of yellow phosphorus. The evaporated yellow phosphorus is condensed, collected and used in a subsequent conversion batch. The red amorphous phosphorus is obtained substantially free from residual unconverted yellow phosphorus and in a physical form which allows ready further processing to particulate form.
