Stearic Acid is a well-known long-carbon, saturated fatty acid. This acid is both a lipophilic long-carbon chain saturated fatty acid and a hydrophilic carboxyl group. Hydrophilic surfaces of nano-calcium carbonate are coated with stearic acid to enhance their lipophilicity. This material is useful for creating a bond between calcium carbonate and polymer molecules. This strong bond can give the product a bright surface and excellent reinforcement performance.
Calcium stearate (white powder) is insoluble in water, coldethanol and alcohol. However, it can be slightly soluble or insoluble in organic solvents, such as hotbenzene. The product is easily combustible when it’s heated up to 400 degrees Celsius. In the case of strong acids, it decomposes to stearic acid or its corresponding calcium sodium. These are hygroscopic.

Here are the four production methods used to make calcium stearate

1. The synthesizing of calcium stearate. A 1074kg/m3 sodium stearate solution is mixed with the calcium chloride solution. The metathesis reaction occurs at approximately 65 degC. Calcium stearate can be separated using Precipitation. To get the final product, it must be filtered.

2. Take 5.60g of calcium oxide (0.1mol) in 300mL. 55 heat water. Mix 51.3g chemically pure Stearic Acid in 350mL boiling water. At 70 degrees, stir and then add 0.75g Diethanolamine. Stir to combine. In 2h, slowly add the prepared Stearic Acid emulsion to the calcium dioxide suspension. After stirring, remove any insoluble matter, such as calcium stearate.

3. To make the catalyst H2O2, add some stearic acid to a pot with a stirrer. Once it has melted, add the catalyst slowly to keep the temperature at 140 to 150. Reaction time: 1.5-2.0 hours. Once the reaction has completed, the material can be discharged and cooled to make the final product.

4. The metathesis method involves dissolved stearic in 20x hot water. Next, you will need to add saturated caustic soy solution. Finally, perform saponification at approximately 75degC. Next, add the 1074kg/m3 calcium chloride solution to the sodium-stearate mixture. After that, perform the metathesis reaction at approximately 65. Calcium stearate is precipitated. To obtain the final product, it must be filtered.
