| 中文摘要: |
| 硫酸掺杂聚苯胺及其聚苯胺盐衍生物可以用于醛和乙酰乙酸乙酯的缩醛化反应,催化剂具有高效,可回收等特性。 同时,利用二元醇作为保护基团,醛也可以转换成相应的乙缩醛。我们还考察了反应时间,温度和催化剂的用量对反应的影响,并对其中的一些产物进行了红外波谱、熔点测定, 1H NMR and 13C NMR 等分析。 |
| 英文摘要: |
| Polyaniline-H2SO4 (PANI) and its derivative polyaniline salts (PABSA) have been used as an efficient and recyclable catalyst for acetalization between aldehydes and acetic anhydride. Aldehydes can also be converted to the corresponding acetals using diols as protection reagents. The influence of reaction time, reaction temperature, and the amount of catalyst were studied. Some of the compounds were characterized by IR spectrum, Mp, 1H NMR and 13C NMR analysis. |
