Stearic Acid → Zinc Stearate

Participants

Reaction Steps

118.1 g of stearic acid and 36.3 g of zinc oxide were stirred at 45° C., and 1.5% of 30% acetic acid was added. During stirring, caking initially occurred on the walls of the reactor, but could be removed. After 5 minutes, the mixture was readily stirrable. A dusty, whitish, slightly voluminous powder having a zinc content of 18.8%, a melting temperature of 128° C., and an acid value of 4.1 was obtained after 10 minutes.
