PRODUCTION OF PHOSPHORUS PENTASULFIDE OF PREDETERMINED REACTIVITY

摘要

PRODUCTION OF PHOSPHORUS PENTASULFIDE OF PREDETERMINED REACTIVITY The invention provides a process wherein a mixture prepared from starting materials comprised of P2S5 of high reactivity and low reactivity, respectively, is converted to phosphorus pentasulfide of predetermined reactivity lying between that of the high reactivity P2S5 and that of the low reactivity P2S5 starting materials. To this end, the starting materials are mixed in quantitative proportions which are selected in accordance with the respective reactivity of the starting materials and the resulting mixture is ground.
