Abstract
Compounds of the formulae <FORM:0993587/C2/1> and [R5R6R7NH]x HyPO4 where each of R1, R2, R3 and R4 is a C1-C10 alkyl group, a C2-C10 hydroxy substituted alkyl group or an aromatic group; R5 is a C1-C10 alkyl group or a C2-C10 hydroxy substituted alkyl group; R6 and R7 are each a C1-C10 alkyl group, a C2-C10 hydroxy substituted alkyl group or hydrogen and x=1-3, y=0-2 provided that x+y=3, are prepared from phosphoric acid and the amine or quaternary ammonium hydroxide. In an example tris-triethyl ammonium phosphate [(C2H5)3NH]3PO4 is prepared. Suitable starting compounds are listed.
