68201-37-6 - Introduction
Octadecanoic acid, also known as stearic acid, is a long-chain saturated fatty acid. Its molecular formula is C18H36O2, structural formula is CH3(CH2)16COOH. Octadecanoic acid has both linear and branched forms.
Nature:
Linear Octadecanoic acid is a colorless crystal with a melting point of 69.6 ° C and a boiling point of 361 ° C. It is soluble in organic solvents such as alcohols and ethers and slightly soluble in water. The branched Octadecanoic acid has similar properties to the linear form.
Use:
Octadecanoic acid has a variety of uses in industry. It is widely used as a raw material for stearic acid in the manufacture of waxes, greases, lubricants and rust inhibitors. In addition, it is also used as a component of emulsifiers, emulsifying ointments, soap bases, surfactants and emulsifying AIDS.
Preparation Method:
Octadecanoic acid can be prepared in a variety of ways. One common method is by saponification of fatty acids. First, the animal and vegetable fats and lye reaction, generating the corresponding fat soap. Then, through the acidification reaction, the acid is separated from most of the water in the base to obtain pure Octadecanoic acid.
Safety Information:
Octadecanoic acid is generally harmless to humans and the environment under normal conditions of use. However, prolonged or heavy exposure can cause skin irritation and allergic reactions. Should avoid direct contact with the skin, such as contact should be immediately washed with soap and water. Appropriate personal protective equipment, such as gloves and glasses, should be worn during use.
In summary, Octadecanoic acid is a commonly used fatty acid and is widely used in industry. It has two forms of linear and branched, has a wide range of uses and a convenient preparation method. However, care should be taken to avoid direct contact with the skin and take appropriate safety measures.
