It is a common saturated long-carbon-chain fatty acid. The hydrophilic carboxyl group and the lipophilic carbon chain end are both present in the stearic acid. Its surface is hydrophilic so it is coated with stearic acids. This can improve 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 a powder that’s insoluble with water, cold alcohol and ether. It’s soluble, however, in organic solvents, such as hot benzene (benzenoic acid), benzene (benzene) and turpentine. 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.
Calcium stearate can be produced in four different ways
1. The synthesis is calcium stearate. The calcium chloride with a concentration of 1074kg/m3 (also known as 10degBe), is added to the sodium-stearate solution, and the metathesis reactions are carried out at approximately 65degC. Precipitation separates calcium stearate. The finished product is obtained after it has been filtered, washed in water and dried around 90degC.
2. In 300mL hot water, add 5.60g of calcium oxide (0.1mol). Pour 51.3g of chemically-pure stearic acids in 350mL at 70°C hot water, and add 0.75g diethanolamine. Stir to emulsify. The prepared stearic-acid emulsion, after being fully stirred for 2 hours, 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. After the reaction, the material must be discharged, cooled, and crushed in order to obtain the finished product.
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. Then, the calcium chloride with a 1074kg/m3 content was added to sodium stearate. Metathesis was then carried out around 65 degrees Celsius, and calcium stearate precipitated. Then, it is filtered and washed in water before being dried at around 90degC.
