| titleOfInvention | High-efficiency reactive distillation method and device for glycol acetal/ketone reaction |
| abstract | The invention relates to a high-efficiency reactive distillation method and a device for glycol acetal/ketone reaction, wherein a reactive distillation tower consists of a distillation section and a reactive distillation section, a glycol raw material is one or a mixture of ethylene glycol, propylene glycol and butanediol, a feed inlet of the reactive distillation tower is arranged at the top of the reactive distillation section, an aldehyde/ketone feed inlet is arranged at the bottom of the reactive distillation tower, an acetal/ketone product is discharged from the top of the reactive distillation tower, and the acetal/ketone product is obtained after the aldehyde/ketone is recovered by an aldehyde/ketone recovery tower. The method and the device are characterized in that the lower half part of the tower is provided with a reaction rectifying section, the reaction heat of the acetal/ketone reaction can be well utilized, the method can obtain high conversion rate in the acetal/ketone reaction of the glycol, the flow is simple, and the method and the device can obtain remarkable economic benefit when being applied to the acetal/ketone reaction of the glycol in the coal-to-glycol or biomass catalytic method to prepare the glycol or other process flows. |
