Conditions

Temperature: 60 °C

Procedure

A slight stoichiometric excess of stearic acid was added to the zinc oxide aqueous slurry. It was heated with agitation to 60° C. to melt the stearic acid. As the melt temperature is approached, the stearic acid reacted with the zinc oxide to produce fine particle size zinc stearate. Fine particle size zinc stearate is used in the rubber and paint industries.
