Overview of 1. butanone and its market application

butanone this important organic solvent, because of its low boiling point, moderate volatility and excellent solubility characteristics, occupies an important position in the chemical industry. Its wide range of applications include chemistry, medicine, coatings, etc., especially in the preparation of high-performance materials, the demand for butanone is more vigorous. With the continuous emergence of new energy, advanced materials and other emerging applications, the butanone market will usher in more opportunities.

Production process and raw material preparation of 2. butanone

the production of butanone mainly relies on two processes: n-butene hydration and sec-butyl acetate reduction. In the n-butene hydration method, the raw material n-butene is hydrated to produce sec-butanol, which is further oxidatively dehydrogenated to obtain methyl ethyl ketone. The reduction law of sec-butyl acetate uses sec-butyl acetate as raw material to produce butanone through reduction reaction.

Raw material preparation is the first step in the production of butanone, of which acetone and ethanol are the two key raw materials. These compounds can be obtained by synthetic processes or by extraction from petrochemical feedstocks. The quality and price of raw materials directly affect the production cost and market competitiveness of butanone.

3. Production Cost Control and Profit Analysis

in terms of cost control, the n-butene hydration method shows obvious advantages. If the raw materials can be matched by themselves, the cost will be 300-400 yuan/ton lower than that of purchased raw materials. In addition, the source and content of n-butene also have a significant impact on production costs, and high-purity n-butene can reduce separation costs, thereby increasing profits.

From a profit point of view, in the past few years, the profit of n-butene hydrated butanone is higher than that of sec-butyl acetate reduction method for most of the time, and the difference between the two profits is about 800-1000 yuan/ton. The profit fluctuation of n-butene water is relatively stable, which is mainly due to its single raw material and simple process.

Impact of 4. Raw Material Price Fluctuation on Production

fluctuations in raw material prices have an important impact on the cost and profit of butanone production. In the n-butene hydration process, the price of n-butene is a key factor affecting the production cost. The n-butene is mainly derived from the separation of C4 products after ether, so the price and supply of C4 after ether will directly affect the cost of n-butene.

In the sec-butyl acetate reduction method, the diversification of raw materials and products makes it more affected by market fluctuations. Fluctuations in the price of feedstock ethanol or hydrogen, as well as the sale of ethyl acetate or hydrogen as a by-product, will have a significant impact on production costs and profits.

Technological Innovation and Process Competitiveness of 5.

With the continuous progress of technology, butanone production process is also constantly optimized. The n-butene hydration method has strong competitiveness because of its simple process, single product and low cost. Although the reduction method of sec-butyl acetate has flexibility, the yield is low and is greatly affected by market fluctuations. Therefore, the sec-butyl acetate reduction method needs to be innovated in technology to improve the yield and reduce the cost, so as to enhance its market competitiveness.

6. Future Market Trends and Process Selection

with the gradual popularization of the application of high alkene C4 from coal, the cost of n-butene hydration is expected to be further reduced, thereby enhancing its market competitiveness. The reduction law of sec-butyl acetate needs to seek breakthroughs in raw material selection, product optimization and technological innovation to meet the challenges of the market.

Previous： The supply in the domestic octanol market exceeded the demand, with the price drop exceeding 2900 yuan/ton.

Next： Analysis of the supply and demand pattern, price trend and growth potential of the m-cresol market, the overall trend in the future is good.
