The nature and use
of octadecanol in the field of chemical production raw materials
1. Introduction

octadecanol, also known as stearyl alcohol, is a common saturated fatty alcohol, which widely exists in nature and chemical production. It has many unique physical and chemical properties that make it an important use in the field of chemical production raw materials. The properties and uses of octadecanol will be discussed in detail in this article.

2. the nature of octadecanol

1. physical properties: octadecanol is a white waxy solid, with a high melting point and boiling point, insoluble in water, but soluble in ethanol, ether and other organic solvents.
2. Chemical properties: octadecanol has the generality of alcohol, which can react with acid to generate ester, react with hydrogen halide to generate alkyl halide, and can also undergo oxidation, reduction, dehydration and other reactions.

3. the use of octadecanol

in the field of chemical production raw materials, octadecanol is widely used, the following are its main application areas:

1. Surfactant: octadecanol can be used as non-ionic surfactant raw materials, such as glyceryl stearate, sorbitan stearate, these surfactants have good emulsification, dispersion, wetting and other properties, widely used in cosmetic, food, medicine and other fields.
2. Plastics and rubber: octadecanol can be used as additives for plastics and rubber, which can improve the toughness and anti-aging properties of materials and extend the service life of products.
3. inks and coatings: octadecanol can be used as additives for inks and coatings, which can improve the fluidity, gloss and other properties of the product, and improve the weather resistance and scratch resistance of the coating.
4. cosmetics: eighteen alcohol can be used as the matrix of cosmetics raw materials, has a good moisturizing, moisturizing effect, can improve the texture and stability of cosmetics.

4. conclusion

as a common saturated fatty alcohol, with unique physical and chemical properties, making it widely used in the field of chemical production raw materials. With the continuous development of science and technology, the application field of octadecanol will continue to expand, bringing more convenience and safety to people's production and life.
