| titleOfInvention | Method for preparing neopentyl glycol |
| abstract | The invention provides a method for preparing neopentyl glycol, which comprises the following steps: 1) diluting a solution containing hydroxy pivalaledhyde (HPA) with an organic solvent to obtain a hydrogenation raw material, wherein the hydrogenation raw material contains 20-40 wt% of HPA and 40-70 wt% of organic solvent; and 2) under the action of the hydrogenation catalyst, carrying out hydrogenation reaction on the hydrogenation raw material obtained in the step 1) and hydrogen to obtain a solution containing the product neopentyl glycol, wherein the hydrogenation catalyst contains copper, zinc and aluminum, or copper, zinc, aluminum and manganese. According to the method provided by the invention, the HPA solution obtained after condensation reaction can be diluted and directly used as the raw material of the hydrogenation procedure, the HPA does not need to be purified from the HPA solution, and the catalyst triethylamine for condensation can even exist in the HPA solution. |
