The calcium stearate production method is simple in process and is low in reaction temperature and energy consumption and low in requirements for equipment as compared with a double decomposition process, no reflux reaction is needed in the later stage of reaction, even general double decomposition process production equipment can produce Calcium stearate is produced by heating stearic acid and calcium oxide: 2 C17H35COOH + CaO → (C17H35COO)2Ca + H2OIt is also the main component of soap scum, a white solid that forms when soap is mixed with hard water. Unlike soaps containing sodium and potassium, calcium stearate is insoluble in water and does not lather well. Commercially it is sold as a 50% dispersion in water or as a spray dried powder. As a food additive The invention belongs to the metal compound preparation technical field, in particular relates to a manufacturing method for calcium stearate. The method comprises the following procedures: (1) the water is added into the calcium hydroxide to make the pulp beating; (2) the stearic acid is dissolved by adding the water and increasing the temperature, and is emulsified by adding the ammonia The product of calcium stearate disclosed by the invention is of certain high purity, is high in quality, and is higher than the standard of national firsts. The production process is simple, the production cost is low, and the preparation process is applicable to industrial production. Calcium stearate, is produced via direct fusion process that Offers excellent purity. Calcium stearate is a derivative of Stearic acid. It exhibits excellent lubricating, dispersing, flow Improvement, hydrophobic properties, stabilizing and foam Inhibiting effects. Calcium stearate Calcium stearate is a food additive permitted for direct addition to food for human consumption, as long as 1) the quantity of the substance added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) any substance intended for use in or on food is of Calcium stearate is a detergent/soap derived from fatty-acids (lipids) which is a conjugate weak acid and alkali (strong base), so its aqueous solution is Alkaline. One major route of calcium stearate production is by the neutralization reaction of stearic acid and calcium hydroxide.
