Syntheses and Characterizations of Two New Organic-inorganic Hybrids Based on Heteropolymolybdates and Piperidine Molecules 总被引:2,自引:0,他引:2
1 INTRODUCTION The rational design and synthesis of organic-inor- ganic hybrid materials have recently attracted an increasing interest not only from a structural point of view, but also due to their potential applications in different areas such as catalysis, medicine, sorption, electrical conductivity, magnetism and photoche- mistry[1~8]. It should be noted that polyoxometalates (POMs)[9~11], known as their wide applications in many interdisciplinary fields, are an outstanding class o… 相似文献

1引言双酚-F(BPF)是用途广泛的化工基础原料,主要用于环氧树脂、聚碳酸酯树脂、聚酯树脂的生产,其优点是制得的树脂粘度低,机械性能和化学性能优良,对化工、国防、电子电器工业、民用等方面都具有重要意义。但国内至今尚无双酚-F的生产厂家,更无双酚-F的分析方法。国外的报道也不多见。双酚-F一般由苯酚与甲醛在酸性介质中反应制得,得到的产物为双酚-F的3种异构体,即4,4-BPF、4-BPF和2,2-BPF。我们研究采用高效液相色谱法分离测定本酚和双酚-F,外标法定量,获得了令人满意的结果。2实验部分2.1实验仪器与试剂日本岛津L… 相似文献
