• Basic Information:
  • Chinese Name: C12-14 fatty alcohol, also known as high - carbon - number fatty alcohol or C12 - C14 alcohol.
  • English Name: Aliphatic alcohol(C12 - C14), Alcohols, C12 - 14. The English alias is tridecan - 1 - ol.
  • CAS No.: 80206 - 82 - 2.
  • Molecular Formula: C13H28O.
  • Molecular Weight: 200.36.
• Chemical Composition: It is mainly composed of dodecyl alcohol (C12 alcohol) and tetradecyl alcohol (C14 alcohol). In the C12 - C14 fatty alcohol sold on the market, the ratio of C12 alcohol to C14 alcohol is usually 7:3. The content of C12 is generally between 73.0% and 75.0%, and the content of C14 is between 23.0% and 27.0%.
• Physical Properties: Usually, it is a colorless oily liquid or solid with a characteristic odor. The density is about 0.832g/cm³, the boiling point is 272.1°C at 760 mmHg, the flash - point is 121.1°C, the vapor pressure is 0.000807mmHg at 25°C, and the refractive index is 1.443. It is soluble in organic solvents such as ethanol and diethyl ether, and insoluble in water.
• Properties and Applications:
  • It has the functions of washing, emulsifying, lubricating, dispersing and defoaming, and is an intermediate for organic synthesis.
  • In the daily - chemical industry, it is the basic raw material of surfactants, synthetic detergents, wetting agents and emulsifiers.
  • In the textile chemical industry, it can be used as a textile auxiliary material.
  • In the printing and dyeing chemical industry, it can play an auxiliary role in the printing and dyeing process.
  • It can also be used as a rubber processing aid and an additive for lubricating grease.
  • In the pharmaceutical industry, it is an intermediate for pharmaceutical ointments.
  • In cosmetics, it can play the roles of moisturizing, softening, antistatic and antioxidant.
• Production Method: The main production methods include coconut oil hydrogenation method and trans - esterification method. The coconut oil hydrogenation method refers to the continuous hydrogenation of coconut oil in a copper - chromium catalyst to obtain a mixed alcohol of C8 - C18. After the mixed fatty alcohol is distilled under normal pressure to remove water and isopropanol, it is distilled under reduced pressure to cut out C12 - C14 alcohol. The trans - esterification method means that coconut oil undergoes a trans - esterification reaction with methanol in the presence of sulfuric acid to generate fatty acid methyl ester and glycerol, and then C12 - C14 fatty alcohol is obtained through further treatment.
• Safety: C12 - C14 fatty alcohol is safe under normal use conditions, but it should be kept away from incompatible substances such as strong oxidants and alkalis.
