Original Abstract Submitted
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 extracting agent and distilling it to obtain an extract and a raffinate; supplying the raffinate to a saponification reactor to be reduced with a catalyst, and supplying the catalyst to an integrated recovery column; supplying the extract solution to an aldol purification column and distilling it to obtain an upper discharge stream and a lower discharge stream; supplying the upper discharge stream from the aldol purification column to the integrated recovery column and supplying the lower discharge stream from the aldol purification column to a hydrogenation reactor to obtain a second reaction product including neopentyl glycol; and obtaining the neopentyl glycol from the second reaction product.
