Background
The aluminum stearate is toxic white or yellowish powder, is insoluble in water, ethanol and diethyl ether, and is soluble in solvents such as alkali, turpentine, mineral oil, petroleum, kerosene and benzene.

The product is used as a heat stabilizer and a lubricant of polyvinyl chloride plastics, an anti-settling agent and a drier in the paint industry, a waterproof agent of fabrics, a thickening agent of lubricating oil and the like, but the saponification rate and the purity of a final product are unsatisfactory in the conventional method, so that a large amount of palm oil is wasted. One of the reasons for the low saponification rate of aluminum stearate and the low purity of the final product is that the oil phase and the aqueous phase are not miscible in the reaction, and the oil phase tends to float and float on the water surface because it is less dense than the aqueous phase, so that mere agitation under water is not sufficient to promote sufficient contact between the oil phase and the aqueous phase; it is also necessary to dissolve the oil droplets in the floating process and the oil phase floating on the liquid surface into the solution sufficiently. In addition, when the existing stirring equipment is used, the situation that the stirring shaft is likely to vibrate when the load of the stirring shaft is too heavy occurs, and the vibration of the stirring shaft can not only cause the stirring equipment to work normally, but also damage components such as a motor and the like.
