The manufacturing method
of butadiene
Butadiene is an important chemical raw material, which is widely used in synthetic rubber, plastic, fiber and other fields. With the continuous development of the chemical industry, the production method of butadiene is also constantly improving, this paper mainly introduces several common butadiene manufacturing methods.
1. Ethanol-based butadiene
Ethanol-based butadiene is a traditional production method, mainly using ethanol as raw material, through dehydrogenation, dehydration, cracking and other reactions to obtain butadiene. The production process of this method is relatively mature and simple to operate, but the raw material consumption is high and the production cost is high. At the same time, more by-products are produced in the production process and need further treatment.
2. Butadiene oxidation
Butene oxidation butadiene is a relatively common production method, mainly using butene as raw material, through the oxidation reaction to obtain butadiene. This method has the advantages of easy availability of raw materials, mild reaction conditions and high yield, so it is widely used in industrial production.
3. Butadiene by butane cracking
Butadiene by butane cracking is a method for obtaining butadiene by cracking butane. This method has the advantages of easy availability of raw materials, low price and high yield, so it has been applied in some areas. However, the production process of this method requires high temperature and high pressure conditions, the equipment investment is large, and at the same time, more by-products are produced, and further processing is required.
4. Acrylonitrile-Process Butadiene
The acrylonitrile-process butadiene is a process for obtaining butadiene by hydrolysis of acrylonitrile. This method has the advantages of easy availability of raw materials, mild reaction conditions, high yield, and less by-products, so it has been applied in some areas. However, the production process of this method requires the use of relatively expensive catalysts, and the waste water produced needs to be treated.
No matter which method is used to manufacture butadiene, it is necessary to consider environmental protection, safety, economy and other factors. In the production process, it is necessary to strictly control the reaction conditions to ensure product quality and yield, while reducing energy consumption and reducing waste emissions, and improving economic and environmental benefits.
In short, butadiene as an important chemical raw material, its manufacturing methods continue to improve and develop, the future will continue to explore new production processes and technologies to meet the growing market demand.
