Used as solvent, dewaxing agent, also used in a variety of organic synthesis, and as raw materials for synthetic spices and medicine.
Butanone is an important component of distilling liquor (wood alcohol oil) of retorted Wood. Industrial production from SEC-butyl alcohol, butane, etc. 1. The mixed C4 fraction containing butyl alcohol in sulfuric acid indirect water method is contacted with sulfuric acid to form acid sulfate and Chinese sulfate, then diluted with water, hydrolyzed to form SEC-butyl alcohol aqueous solution, and then dehydrated and concentrated to SEC-butyl alcohol. After the pure SEC-butyl alcohol is catalysed by nickel or zinc oxide, the finished product is obtained. 2. Direct hydration of N-butene this method is divided into two types, one with resin as catalyst and the other with heteropolyacid as catalyst. 3. Sec-butyl alcohol the process of the process of the gas phase method and liquid phase method, most of the gas phase method of the process of the process. That is to say, SEC-butyl alcohol is converted to butanone by the action of the catalyst. 4. Ethylene gas phase oxidation method. 5. Isobutylbenzene process n-Butene and benzene are hydrocarbonized to generate isobutylbenzene, isobutylbenzene is oxidized to generate hydrogen peroxide isobutylbenzene, and finally butanone and phenol are decomposed by acid. The characteristics of this method are: the corrosion of process equipment is light and the reaction conditions are mild, which is conducive to industrialization.
