Abstract

Scale inhibiting compsns. comprising (a) a mixt. of cpds. of formula: and (b) one or more cpds. of formula: (RO)2PSM (where R is radical contg. >=6C atoms or an oxyalkylated radical, X is O or S, each of the cpds. (a) contains both O and S, and M is H or a metal) are prepd. by reacting one or more alcohols with P2S5 to form o, o-disubstd. dithiophosphoric acid(s) until all the P2S5 has dissolved and H2S evolution has ceased, and continuing the reaction to convert eha cid to the pyrophosphates with the proviso that where M is a metal the acis(s) are neutralised with a salt-forming base or by double decompsn. Esp. useful in crude pil handling equipment and steam generating appts.
