Design of orthogonal test and determination of optimum technological conditions for direct synthesis of zinc stearate
The method for direct synthesis of zinc stearate from stearic acid and zinc oxide in presence of catalyst was studied. The optimum technological conditions were obtained by orthogonal test and verification test as follows. The reaction time was 90min, temperature was 135℃, peroxidate was used as catalyst with amount of 3% to the weight of stearic acid. This process had advantages of short flow, simple process, low cost, and no waste water. The quality of zinc stearate product was accorded with the demands of literature reported.
