HCID 86583601Lithium styrene sulfonate

Procedure

Purolite C-100E, C-120E, C-145 or C150 (The Purolite Co., Bala Cynwyd, Pa.,USA). The yield from the ion exchange column is about one liter of hydrogen styrene sulfonate, which is then neutralized by addition of LiOH.H2O powder (approximately 33 g) until the pH of the solution is about 7. The resulting solution of lithium styrene sulfonate in water is dried. A yield of about 143 g lithium styrene sulfonate (a white or grey powder) with a water content of about 9.9% is obtained.
