p-Toluenesulfonic acid → Zinc di(toluene-4-sulphonate)

Participants

Reaction Steps

To an appropriate vessel there is charged 618 gms (7.6 moles) of zinc oxide in an aqueous slurry. With vigorous stirring there is slowly added to the charge 650 gms (3.8 moles) of p-toluene sulfonic acid in 1 liter of water. The resulting reaction mixture produces an exotherm and heats up to a temperature of circa 100° C. With continued stirring, the mixture is allowed to cool to room temperature and then stood overnight. The crystal precipitate is then separated by filtration, washed and dried to obtain zinc p-toluene sulfonate.
