一种链状磷酸铝骨架化合物的离子热合成与表征

以苯甲酸/氯化胆碱形成的离子型低共熔混合溶剂(DES)作为反应介质,采用离子热合成方法研究了磷酸铝骨架材料的合成规律.结果表明,体系中不添加正丙胺时得到的是一种致密的磷酸铝相,体系中氯化胆碱无法发挥模板作用;当添加适量的正丙胺后,合成出一种已知链状结构的磷酸铝化合物(AIPO_4-PrN),并对样品进行了表征.和体系中的氯化胆碱组分相比,添加的正丙胺具有较强的结构导向作用,在形成AIPO-PrN材料时起到了模板或结构导向作用,而苯甲酸/氯化胆碱形成的DES只是作为离子热反应介质.

Ionothermal synthesis of an aluminophosphate compound with chain structure and its characterization

By using the ionic deep-eutectic solvent formed of benzoic acid and choline chloride as reaction medium,the synthesis conditions of aluminophosphate framework materials are investigated by ionothermal approach.The results show that only dense phases can be formed when there is no n-propylamine in presence,and choline chloride cannot behave as a template.After the addition of n-propylamine an aluminophesphate compound(designated AIPO_4-PrN)with known chain structure can be synthesized.And the samples are characterized.n-Propylamine provides a stronger template compared to the choline chloride existing in the system.and acts as template or structure-directing agent during the formation of AIPO-PrN material.The deep-eutecfic solvent consisted of benzoic acid and choline chloride only works as the ionic liquid solvent.
