| titleOfInvention | Method for preparing purified MIBK from industrial byproduct waste liquid acetone |
| abstract | The invention discloses a process for preparing high-purity MIBK by using industrial byproduct waste liquid acetone. Comprises industrial byproduct waste liquid acetone and MIBK synthetic liquid synthesized by the industrial byproduct waste liquid acetone, wherein light components with the boiling point lower than that of acetone are obtained at the top of a light component removing tower, and unreacted acetone is obtained at the top of an acetone recovery tower; obtaining organic matters with boiling points lower than the MIBK/water azeotrope and the MIBK/water azeotrope at the top of the process water tower; low boiling point organic matters such as acetone, methanol and the like from raw materials are obtained at the top of the dehydrating tower; obtaining an alcohol/water distillate at the top of the dealcoholization tower and a crude MIBK distillate at the bottom of the dealcoholization tower; obtaining light components with the boiling point lower than that of the MIBK at the top of the MIBK refining tower and obtaining the MIBK with the purity more than or equal to 99.5 wt% at the lateral line. The method has the advantages of simple technical process, low energy consumption and low production cost, can obtain high-purity MIBK products by using high-impurity waste liquid acetone, and has remarkable economic benefit. |
