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

Octanediol is an important organic chemical raw materials, widely used in medicine, cosmetics, plastics, coatings and other fields. In this paper, the properties and uses of octanediol are introduced in detail.

2. octyl glycol properties

1. physical properties: octyl glycol is a colorless and transparent, with a pleasant smell of liquid, with water, ethanol, ether and other organic solvents miscible, slightly soluble in petroleum ether. Its vapor pressure is low, not volatile, stable to heat, not easy to oxidize.
2. chemical properties: octanediol has a certain acidity and alcohol generality, can occur esterification, etherification, oxidation and other reactions. In addition, octanediol has oxidation resistance and can be used as an antioxidant.

3. Octanediol Uses

1. Pharmaceutical Field: Octanediol can be used as a drug carrier to improve the solubility and stability of drugs, and can also be used in the manufacture of antibacterial agents and preservatives.
2. Cosmetics field: Octanediol has good moisture retention and permeability, and can be used in cosmetics as a moisturizer and penetrant to improve the effect and use experience of cosmetics.
3. Plastic field: Octanediol can be used as a plastic plasticizer to improve the flexibility and processability of plastics.
4. coating field: octanediol can be used as a coating solvent to improve the leveling and gloss of the coating.

4. octanediol production methods

octanediol production methods are mainly the following:

1. Ethylene oxidation: ethylene as raw material, through the oxidation reaction of ethylene oxide, and then react with water to produce ethylene glycol.
2. Chloroethanol method: using chloroethanol as raw material, ethylene glycol is generated by hydrolysis reaction.
3. Esterification method: acetic acid and ethylene glycol are used as raw materials to generate diethyl acetate through esterification reaction, and then ethylene glycol is generated through hydrolysis reaction.

5. Octanediol Market Prospect

With the continuous development of science and technology, octanediol is more and more widely used, and the market demand is also increasing. In the future, as people's requirements for environmental protection and health are getting higher and higher, octanediol, as an environmentally friendly and safe chemical raw material, its market prospects will be broader.

6. conclusion

In conclusion, octanediol, as an important organic chemical raw material, has a wide range of uses and good market prospects. In the future development, we should continue to increase research and development efforts to improve the production technology and application level of capsiol to meet the growing market demand and promote the sustainable development of the chemical industry.
