Process for the removal of sodium from sodium-containing heavy fractions from anprocess for the combined production of styrene and propylene oxide comprising admixingnan aqueous solution of an organic carboxylic acid to the heavy fraction at a temperaturencomprised between 20°C and 100°C, and separation of the organic phase from thenaqueous phase, wherein the organic phase contains less than 0.5% by weight ofnpolymeric solids. The obtained organic phase has low viscosity and ash content and cannbe used directly as a fuel. |
