Abstract
Using stearic acid and zinc oxide as raw materials,high-quality zinc stearate with good lustre was synthesized by hydrothermal method.The research results showed that the reaction rate was affected in different degree by the particle size of zinc oxide,the reaction temperature and the(liquid-)solid ratio of the reactants.By using particle zinc stearate passing sieve of 74 μm as raw material,main factors influencing the synthesis of zinc stearate were obtained through orthogonal experiment design as well as the following optimum reaction conditions:the liquid-solid ratio of the reactants was 7∶1,reaction time was 30 minutes,reaction pressure was 0.4 MPa and reaction temperature was 60 ℃.
