n-Butanol is an important raw material for chemical production, which has a wide range of properties and uses. In this paper, the properties, production methods, uses and market prospects of n-butanol will be introduced in detail.

1. the nature of n-butanol

n-butanol is a colorless, transparent, flammable, alcohol-flavored gas, molecular formula C4H10O, molecular weight of 74.12. n-Butanol has a relatively high boiling point of 117.7 ° C., so it is easier to separate and purify. In addition, n-butanol also has good solubility and chemical stability, can be miscible with a variety of organic solvents, and can be stable in acid, alkali and other conditions.

2. n-butanol production methods

n-butanol production methods mainly include fermentation, acetaldehyde, ethylene, etc. Among them, fermentation is one of the most commonly used production methods, mainly using microorganisms to ferment sugars to generate n-butanol and carbon dioxide and other products. The acetaldehyde law is based on acetaldehyde as raw material, through the hydrogenation reaction to produce n-butanol. The ethylene law is to produce ethanol by ethylene hydration, and then to produce n-butanol through dehydrogenation reaction.

3. the use of n-butanol

n-butanol as an important chemical raw material, widely used in medicine, coatings, plastics, spices and other fields. Specifically, the use of n-butanol includes the following aspects:

1. pharmaceutical field: n-butanol can be used to produce a variety of drugs, such as antibiotics, vitamins and so on. In addition, n-butanol can also be used as a solvent and preservative for the production of pharmaceutical preparations and medical devices.

2. Coating field: n-Butanol can be used as a solvent and additive in the coating to improve the fluidity and drying performance of the coating and improve the performance and quality of the coating film.

3. plastic field: n-butanol can be used to produce a variety of plastic products, such as artificial leather, plastic film, etc. At the same time, n-butanol can also be used as a plasticizer and stabilizer in plastic processing to improve the processing performance and long-term use performance of plastics.

4. spices field: n-butanol has a wine aroma, can be used to produce a variety of spices and flavors, such as food flavors, daily cosmetics flavors and so on.

4. market prospects

With the continuous progress of science and technology and the continuous expansion of application, the market prospect of butanol is very broad. In the future, the application field of n-butanol will be further expanded, especially in the fields of new energy and new materials. At the same time, with the continuous improvement of environmental awareness and the requirements of sustainable development, the production process and technology of n-butanol will be continuously improved and optimized to improve its environmental protection and economy.

In short, n-butanol, as an important raw material for the production of chemicals, has a wide range of properties and uses, and the future market prospects are very broad.
