Procedure

The initial temperature of the zinc oxide and propionic acid were varied, as was the time at which the high-shear blades were engaged. Vent stack temperatures approximately six inches from the top of the mixer were monitored as a measure of the rate of reaction. Each batch was prepared by charging the mixer with 77 pounds of zinc oxide followed by spraying the dry zinc oxide with 140 pounds of propionic acid at nine pounds per minute. Starting material temperatures and the time at which the high-shear mixing blades ("choppers") were engaged are summarized below in Table 1.
