| Abstract | Provided is a method for preparing neopentyl glycol including: performing an aldol condensation reaction to obtain a first reaction product including hydroxypivaldehyde; bringing the first reaction product into contact with an extractant and distilling it to obtain an extract and a raffinate; supplying the raffinate to a saponification reactor to be reduced to the catalyst and supplying the catalyst to an integrated recovery column; supplying the extract to an aldol purification column and distilling it to obtain a lower discharge stream and an upper discharge stream; supplying an upper discharge stream from the aldol purification column to the integrated recovery column and supplying a lower discharge stream from the aldol purification column to a hydrogenation reactor to obtain a second reaction product including neopentyl glycol; and obtaining neopentyl glycol from the second reaction product. |
