Procedure

A solution of 176 parts sodium sulfate in 800 parts water was added to the residue at 60° to 70° C., followed by stirring for 5 hours at 80° to 95° C. A clear viscous solution having a solids content of 43.6%, a sulfite content of 0.04% and an inorganic sulfate content of less than 0.03% was obtained.
