Stearyl acrylate(Stearyl acrylate) is an organic compound with the chemical formula C21H40O2. The following is a description of its nature, use, preparation and safety information:
Nature:
-Stearyl acrylate is a colorless to pale yellow liquid with a special fragrance.
-Its density is 0.868g/cm3, and it solidifies into white crystals at room temperature.
-Stearyl acrylate is insoluble in water, but can be dissolved in some organic solvents such as alcohols.
Use:
-Stearyl acrylate are commonly used as monomers for polymers. It can be copolymerized with other monomers such as butyl acrylate (butyl acrylate) or acrylonitrile (acrylonitrile) by free radical polymerization to prepare copolymers with different properties.
-It is widely used in industries such as coatings, inks, adhesives and lubricants.
Preparation Method:
-The preparation of Stearyl acrylate is usually obtained by reacting acrylic acid with octadecanol. This reaction is carried out in the presence of an acid catalyst or an esterification catalyst to produce a Stearyl acrylate.
Safety Information:
-Stearyl acrylate is a flammable liquid and should avoid contact with high temperatures, open flames and oxidants.
-Contact with Stearyl acrylate may cause irritation to skin and eyes. Therefore, contact with skin and eyes should be avoided during use.
-When handling Stearyl acrylate, pay attention to good ventilation conditions and avoid inhaling its vapor or mist.
-In case of accidental leakage, appropriate cleaning methods should be taken to prevent it from entering the drainage system or the environment.
Please note that the above information is for reference only and does not represent the whole story. When using or operating the Stearyl acrylate, be sure to refer to the specific safety technical documents and operating procedures it involves.
