| titleOfInvention | A kind of method and device for preparing tert-butyl acetate |
| abstract | The invention relates to a method and a device for preparing tert-butyl acetate, which mainly comprises sending a mixture of tert-butyl acetate, C8 and tert-butanol obtained from the top of a tert-butyl acetate refining tower into an extraction tower for extraction, and the C8, tert-butyl acetate Butyl ester is extracted from the top of the extraction column, and the mixture of tert-butanol and water is extracted from the bottom of the column; the mixture of tert-butanol and water extracted from the bottom of the extraction column is sent to the rectifying column for separation, and the tert-butanol containing water is extracted from the column. The top of the tower is extracted, and the water is extracted from the tower bottom. The method provided by the invention successfully solves the problems of low recovery rate of tert-butyl acetate, many reaction by-products and low recovery rate of tert-butanol in the prior art, and the method provided by the invention can effectively suppress the occurrence of side reactions, By-products after the reaction are reduced, the pyrolysis of tert-butyl acetate is inhibited, and the selectivity and yield of tert-butyl acetate are improved. The method of the invention is simple in process, easy to operate and low in energy consumption. |
