Precipitation reaction of lead stearate
Oct 09, 2018

Fatty acids are first heated in water at temperatures above its melting point, where the amount of water is more than 20 times times the amount of the fatty acid, and then a saponification reaction (such as sodium hydroxide solution, potassium hydroxide solution, ammonia, etc.) occurs with the alkali solution of the Mole.   The resulting alkaline soap dissolves in the Water.subsequently, the water-insoluble metal saponification is made by adding a metal salt solution (for example, Calcium chloride solution, Aluminum sulfate solution).
