Ethylene acetone and acetone are two common chemical raw materials, which have important applications in industrial production and chemical experiments. Although they have some similarities in name, there are obvious differences in chemical structure and use.

ethylene acetone and acetone differ in chemical structure. Ethylene acetone chemical name, also known as propylene ketone, is a kind of ketone compound containing double bond structure, its chemical formula is C3H4O. Acetone is the abbreviation of acetone-based aldehyde, and its chemical formula is C3H6O. In terms of chemical structure, ethylene acetone has one more carbon-carbon double bond than acetone, which is the fundamental reason for the difference in their properties and uses.

ethylene acetone and acetone differ in use. Ethylene acetone is mainly used in the production of resins, coatings, paint thinners, adhesives, solvents and cosmetic raw materials, and can also be used in the preparation of detergent raw materials such as propylene oxide. Acetone is mainly used in the production of solvents, detergents, synthetic fibers and rubber, and can also be used in the fields of medicine, chemical industry and printing.

In addition, the process and performance of ethylene acetone and acetone in industrial production are also different. The production of ethylene acetone needs to be obtained by the catalytic oxidation reaction of propylene (butyl acrylate), acetic anhydride and other raw materials, while acetone is obtained by the oxidation reaction of propane and air or oxygen under the action of a catalyst. In the industrial production process, the stability and volatility of ethylene acetone are poor, while acetone is relatively stable and volatile.

In summary, there are significant differences between ethylene acetone and acetone in chemical structure, use and production process. In industrial and chemical applications, it is necessary to select suitable chemical raw materials according to specific production purposes and requirements. At the same time, for ordinary consumers, understanding the difference between these chemical raw materials can help choose the right product and understand the production process of the product.
