ABSTRACT:
In the co-production oxide and styrene monomer, there is produced a sodium-containing heavy residue stream previously suitable only as a low grade fuel. In accordance with the invention, the heavy residue stream is contacted with aqueous acid, and the resulting mixture is phase separated into an aqueous sodium-containing phase and an organic phase reduced in sodium, and at least a portion of the organic phase reduced in sodium is converted to styrene monomer.
