What does calcium stearate mean?
Calcium stearate can be described as an organic compound having a molecular formula C36H70CaO4. It’s a powder that is white and insoluble when water.
Calcium stearate can be described as a calcium salt that has been derived from calcium dioxide and stearic acids. It is used in many cosmetics, plastics and food products. Both pros and cons are associated with calcium stearate.
Synthesis of calcium Stearate
1. The synthesizing of calcium stearate. A 1074 kg/m3 sodium stearate solution is mixed with the calcium chloride solution. The metathesis reaction occurs at approximately 65°C. Calcium stearate can be separated using Precipitation. To obtain the final product, it must be filtered.
2. Take 5.60g of calcium oxide (0.1mol) in 300mL. Add 55 hot water. Mix 51.3g chemically pure Stearic Acid in 350mL boiling water. At 70degC, stir. Finally, mix 0.75g Diethanolamine into the mixture and whisk to combine. In 2 hours, slowly add the prepared stearic acids emulsion to the calcium dioxide suspension. After stirring, filter out the insoluble material, which is calcium stearate. Dry the product.
3. Direct method: Add a little stearic acid to a pot with a stirrer, a thermometer and a whisk to heat the mixture to melt. Next, slowly add the catalyst H2O2 and keep stirring. The reaction temperature should be controlled at 140-150 degrees Celsius by using a vacuum. It takes 1.5-2.0 hours for the reaction to occur. Once the reaction has completed, the material can be discharged and cooled before being crushed to make the final product.
4. The metathesis method: Take 20ml of hot water and dissolve the stearic Acid. Next, mix in saturated caustic soy solution. Finally, perform saponification at approximately 75degC to produce dilute sodiumstearate solution. Next, the sodium-stearate solution contained 1074kg/m3. The metathesis reaction occurred at approximately 65. Calcium stearate then precipitated. To obtain the final product, it must be filtered.
Calcium Stearate Application
Calcium stearate may be used to stabilize polyvinyl chloride’s heat, as well as a lubricant in many plastic processing and as a mold release agent. The speed of gelation can be increased by mixing basic lead salt with lead soap.
Also, calcium stearate can be used to make non-toxic soft materials and appliances like food packaging or medical devices. You can use calcium stearate as a halogen absorbent to polyethylene or polypropylene in order to reduce the negative effects of residual catalysts on color and stability.
Calcium stearate, used for rubber processing, is used to soften synthetic and natural rubber. However, it has little effect on vulcanization. This is a polyolefin-based lubricant and molding compound, as well as a thickening, waterproofing, adhesive, paint and glue, and in the production of plastic records. Useful as: halogen absorbent in Polyethylene and Polypropylene, lubricant/release agents for thermosetting plastics like phenolic and amin; thickening and grease agent; waterproofing agent; paint flattening agent; and pencil lead lubricant. Anticaking agent uses food-grade calcium stearate.
The production of pencil lead, medicine and perfume industries also use calcium stearate.
