Abstract:

The reactivity of amorphous red phosphorus specimens obtained from six commercial manufacturers was investigated by a non-isothermal reaction with a sulfuryl chloride-benzene medium. Variations in the reactivity of the phosphorus specimens were measured. The reaction was found to be a pseudo-first reaction, 2 P 3 SO2Cl2 to 3 SO2 2 PCl3, the rate mechanism of which is represented by the differential equation dTdt b Tm-T. Various chemical and physical properties of the phosphorus were investigated in a search for the underlying causes of the observed differences in reactivity, although no single property was found to account for these differences in all the samples.
