摘要:

比较了三种常规合成方法制备1,3-双(3-三乙氧基硅丙基)-咪唑氯鎓时,甲苯、乙腈做溶剂和无溶剂条件对产品收率的影响,认为溶剂极性较大和反应温度较高时更有利于反应的进行;同时,首次采用微波辐照法合成了1,3-双(3-三乙氧基硅丙基)-咪唑氯鎓,并考察了微波辐照功率、时间、投料比等对产品收率的影响;与常规合成方法相比,微波辐照合成1,3-双(3-三乙氧基硅丙基)-咪唑氯鎓具有反应时间短、收率高、不需要有机溶剂和操作方便等优点。该研究为快速、高效合成1,3-双(3-三乙氧基硅丙基)-咪唑氯鎓提供了新方法,为其他类似双硅烷化的有机硅前体的合成提供了新思路。

Abstract:

The effects of three conventional synthetic methods using toluene as the solvent, acetonitrile as the solvent and solvent-free conditions on the yield of 1,3-bis(3-triethoxysilylpropyl)-imidazolium chloride were compared, it was considered that the higher the solvent polarity and the higher the reaction temperature, the better the reaction. At the same time, 1,3-bis(3-triethoxysilylpropyl)-imidazolium chloride was synthesized by microwave irradiation for the first time, and the effects of microwave irradiation power, time and feed ratio on product yield were examined. The synthesis of 1,3-bis(3-triethoxysilylpropyl)-imidazolium chloride under microwave irradiation had the advantages of short reaction time, high yield, no need for organic solvents and convenient operation compared with the conventional synthesis methods. This study provided a new method for the rapid and efficient synthesis of 1,3-bis(3-triethoxysilylpropyl)-imidazolium chloride and a new idea for the synthesis of other similar silanyl precursors.

Key words: 1,3-bis(3-triethoxysilylpropyl)-imidazolium chloride, solvent, microwave irradiation, synthesis
