Document Type and Number:
WIPO Patent Application WO/2020/248483
Kind Code:
A1
Abstract:
Disclosed is a preparation process of stearate, which is a method for preparing stearate by directly reacting a metal oxide or hydroxide with stearic acid. The process not only has simple steps, uses a small number of devices, requires a small amount of investment, and produces no waste liquid, but also eliminates environmental pollution, saves a lot of caustic soda, and reduces the cost of products. Moreover, the loss of raw materials during the process is low, so that the yield of the product is increased. The yield of finished stearate is more than 98% on the basis of stearic acid. In addition, because no other salts are produced during the preparation process, the content of inorganic salts in the stearate product is low, thereby facilitating the improvement of the quality of products.
