摘要:

以异长叶烯酮为原料,经肟化反应合成了异长叶烯酮肟。分别采用单因素法及正交试验法考察了工艺条件对反应产率的影响,确定了最佳工艺条件为:反应时间6 h,反应温度76 ℃,以醋酸钠为催化剂,n(异长叶烯酮):n(盐酸羟胺):n(催化剂)1:1.3:0.55。在此条件下,异长叶烯酮肟的产率>99 %。采用FT-IR、1H NMR、GC-MS和单晶X衍射等分析手段对化合物的结构进行了表征,研究了异长叶烯酮肟对几种金属离子的络合性能,结果表明:异长叶烯酮肟与Cu2+的作用明显强于与Co2+、Cd2+、La3+、Pb2+、Ag+等金属离子的作用;异长叶烯酮肟与Cu2+主要是通过分子中氮原子和氧原子与Cu2+的配位作用进行络合。

Abstract:

Isolongifolenone oxime was prepared from isolongifolenone and hydroxylamine hydrochloride by oximation reaction. Effects of the reaction conditions on the yield of isolongifolenone oxime were investigated by single factor method and ortnogonal experiments. The optimum reaction conditions were as follows:sodium acetate as the catalyst, the molar ratio of isolongifolenone, hydroxylamine and sodium acetate 1:1.3:0.55, reaction temperature 76 ℃ and reaction time 6 h. The yield of isolongifolenone oxime reached 99.0% under the optimum reaction conditions.The structure of the isolongifolenone oxime was determined by FT-IR, 1H NMR, GC-MS and single crystal X-ray diffraction. Complexation properties of isolongifolenone oxime on metal ions including Cu2+, Co2+, Cd2+, La3+, Pb2+, Ag+ were examined, and the results showed that isolongifolenone oxime exhibited better complexing effect to Cu2+ than that to other metal ions. It was also known from the FT-IR that the complexation between Cu2+ and isolongifolenone oxime was formed by Cu-N and Cu-O coordination bonds.

Key words: isolongifolenone oxime, isolongifolenone, oximation, metal complex
