| 摘 要： | 由甲醛、异丁醛经醇醛缩合－ 加氢两步法制新戊二醇。所用的催化剂分别为三乙胺和Ｃｕ － Ｚｎ － Ａｌ。结果表明该催化体系具有活性高、选择性好等特点。在甲醛、异丁醛缩合过程中，异丁醛转化率９４－６ ％ ，羟基戊醛选择性９８－４ ％ ；在羟基戊醛加氢过程中，羟基戊醛转化率１００ ％ ，新戊二醇选择性１００ ％ 。该工艺有较好的工业应用前景。

| Abstract: | Neopentyl glycol was prepared by condensation of formaldehyde and isobutyraldehyde followed by hydrogenation;the catalysts used were triethylamine and Cu-Zn-Al respectively.The result show that the catalysts system have higher reactivity and selectivity.In condensation of isobutyraldehyde and formaldehyde,the conversion of isobutyraldehyde is 94 6%,with a 98 4% selectivity of hydroxypentylaldehyde.In hydrogenation of hydroxypentylaldehyde, the conversion of hydroxypentylaldehyde is 100%,with a 100% selectivity of neopentyl glycol.It could be used for neopentyl glycol synthesis in industry. |
