Abstract

The reactivity of phosphorus pentasulphide is controlled by cooling molten P4S10 through the temperature range 280-260 DEG C. for a time of 0.125-150 seconds. The controlled cooling can be effected on solid ready made P4S10 or on molten newly prepared P4S10 made by interaction of the elements. Examples are given.
