Properties and Uses
of Hexadecyl Alcohol
1. Introduction

hexadecyl alcohol, also known as palmityl alcohol, is a common raw material for chemical production. It is a saturated fatty alcohol with 16 carbon atoms, which has good stability and a wide range of uses. This article will detail the properties and uses of hexadecanol.

2. The properties of hexadecanol

1. Physical properties

hexadecanol is a colorless or slightly yellow solid with a special odor. It has a high melting point, usually between 50-54°C, and a boiling point between 250-260°C. Cetyl alcohol is insoluble in water, but is miscible with many organic solvents such as ethanol, ether, acetone, etc.

2. chemical properties

hexadecanol has typical alcohol chemical properties, can occur esterification, etherification, oxidation and other reactions. In addition, it can also undergo dehydration reactions under acidic conditions to produce olefins. The use of

3. hexadecyl alcohol

1. Surfactant

hexadecyl alcohol can be used as a raw material for non-ionic surfactants. For example, it can react with ethylene oxide to generate ethoxylated palm alcohol. This type of surfactant has good emulsification, wettability and dispersibility, and is widely used in textile, printing and dyeing, papermaking and other industries.

2. Plastic and rubber additives

cetyl alcohol can be used as an additive for plastics and rubber, which can improve the oxidation resistance and thermal stability of the material and extend the service life of the material.

3. Cosmetic raw material

hexadecanol has good moisturizing and ductility, and can be used as raw materials for cosmetics, such as moisturizers, lipsticks, etc.

4. Biodiesel

Cetyl alcohol can be used as the raw material of biodiesel, and fatty acid methyl ester reaction to produce biodiesel, which has the advantages of environmental protection and renewable.

4. conclusion

cetyl alcohol as a common chemical production raw material, has a wide range of uses and good stability. In the future development, with the progress of science and technology and the improvement of environmental awareness, the application of cetyl alcohol in the field of chemical production will be more extensive.
