Abstract
Wet-process phosphoric acid which is obtained by the acidulation of uncalcined phosphate rock with sulphuric acid and which typically contains 28-31% P.sub.2 O.sub.5 and measurable amounts of solid organic materials, such as, for example 0.1% or more, is treated to remove the solid organic materials contained therein by intimately contacting the acid with a liquid hydrocarbon so that the aqueous is the continuous phase, resulting in the solid organic materials being taken up by the organic phase.
