Abstract: Butanol is an important organic chemical raw material, which has a wide range of applications in the field of chemical production raw materials. Butanol is an important organic chemical raw material
. This paper introduces the properties, production methods, uses and market prospects of butanol in detail, aiming to deepen the understanding and understanding of butanol as an important chemical raw material.

1. Properties of Butanol

Butanol is a saturated monohydric alcohol containing four carbon atoms with the formula C4H10O. It has the characteristics of colorless, transparent, flammable, volatile, and has a special smell. Butanol has a boiling point of 117.7°C, a melting point of -89.5°C, a relative density of 0.8109°C, and a flash point of 29°C. In addition, butanol has good solubility and chemical stability, and can be miscible with water, ethanol, ether and other solvents.

2. butanol production methods

butanol production methods mainly include fermentation method, acetaldehyde method, Rayper method and so on. Among them, the fermentation method is the earliest production method, mainly using starch or sugars as raw materials, through microbial fermentation to obtain butanol. The acetaldehyde method is the addition reaction of acetaldehyde with hydrogen under the action of a catalyst to produce butanol. Raper's law is the production of n-butyraldehyde by propylene carbonyl synthesis, and then the hydrogenation reaction to produce n-butanol.

3. the use of butanol

1. solvent: butanol as an excellent solvent, widely used in coatings, inks, resins, rubber, dyes and other fields. Because of its good solubility and chemical stability, butanol has high application value in the preparation of various solvents.
2. Plasticizer: Butanol can be used as a plasticizer for plastics and rubber, which can increase the flexibility, ductility and elasticity of materials.
3. Chemical raw materials: Butanol can be used to produce a variety of chemical raw materials, such as butyraldehyde, butyric acid, butylamine, etc. These compounds are widely used in the fields of medicine, pesticide, spice and so on.
4. Fuel additives: Butanol can be used as a fuel additive to improve fuel combustion performance and environmental protection.

4. Market Prospect

With the continuous development of science and technology, butanol has a very broad application prospect in the field of raw materials for chemical production. In the future, with the rapid development of new energy, new materials and other fields, the market demand for butanol will further increase. At the same time, with the improvement of environmental awareness and the promotion of green chemical technology, butanol as an environmentally friendly solvent and chemical raw material, its market position will be more stable.

conclusion: Butanol, as an important organic chemical raw material, has a wide range of applications in the field of chemical production raw materials. Its excellent properties and wide range of uses make butanol highly valuable in the market. With the continuous development of science and technology, the application prospect of butanol will be more broad.
