ABSTRACT:
A product consisting essentially of an acid orthophosphoric acid ester salt and containing at most about 1 weight % of water is made. The ester group R contains 1 to 50 carbon atoms, and the salt-forming cation M is a mono- or bivalent metal ion or an ammonium ion. To make the product, molar proportions of P.sub.2 O.sub.5 and of a compound of the general formulae M.sub.2 O, M.sub.2 CO.sub.3, MO or MCO.sub.3 are reacted at about 0.degree. to 150.degree. C, with thorough agitation, with 2/m mol of an at least partially liquid or molten organic hydroxyl compound of the general formula R(OH).sub.m, in which formulae the substituents M and R have the meanings given above and m is a number of 1 to 4. The reaction is terminated and the reaction product is cooled.
