It is a common saturated long-carbon-chain fatty acid. It is a saturated fatty acid with a long carbon chain. The surface is hydrophilic of the nano-calcium carbonate, so it is coated with stearic acids to increase its lipophilicity. The large specific surface area of the calcium carbonate and its high specific surface energies make it a good filler for rubber, plastics or advanced inks. The bond between the two can enhance the performance of the product and make it brighter.
Calcium stearate, which is white, is insoluble with water, cold alcohol and ether. It’s soluble, however, in organic solvents, such as hot benzene. It decomposes when heated up to 400degC. If a strong acid is used, it will decompose into stearic acids and the calcium salt corresponding to that acid.

Four different production methods for Calcium Stearate

1. The synthesis is calcium stearate. The calcium chloride with a concentration of 1074kg/m3 (also known as 10degBe), is added to a sodium stearate preparation prepared earlier. Metathesis occurs at approximately 65degC. Precipitation separates calcium stearate. The product is dried and filtered at around 90degC.

2. In 300mL hot water, add 5.60g of calcium oxide (0.1mol). Pour 51.3g of stearic pure acid in 350mL at 70°C hot water, and add 0.75g diethanolamine. Stir to emulsify. The stearic-acid emulsion, prepared within 2 hours and thoroughly stirred, was slowly added to the suspension of calcium oxide.

3. The catalyst H2O2 is added slowly under constant stirring to the reaction pot. The reaction lasts 1.52.0h. The reaction is complete when the material has been discharged and then cooled.

4. Metathesis method – dissolve stearic acids in hot water 20 times their mass, add caustic soda saturated solution, and perform saponification reactions at around 75degC. You will get dilute sodium stearate. The sodium stearate is then mixed with the calcium chloride solution containing 1074kg/m3. Metathesis is carried out around 65 degrees Celsius, and finally the calcium stearate product precipitates out. Then, it is filtered and washed in water before being dried at around 90degC.
