Abstract The syntheses of barium, cadmium, calcium, lead, and strontium apatites were performed in anhydrous polar organic solvents such as DMSO, anisole, pyridine, glacial acetic acid, ethanol, methanol, and DMF. Reactions took place under anhydrous conditions at temperatures ranging from 80 to 120 °C and for durations of 1–6 days. Ten apatites were synthesized in nonaqueous solvents and three (PbApF
摘要在无水极性有机溶剂(如DMSO,苯甲醚,吡啶,冰醋酸,乙醇,甲醇和DMF)中进行钡,镉,钙,铅和锶磷灰石的合成。反应在无水条件下于80至120°C的温度下进行,反应时间为1-6天。在非水溶剂中合成了十个磷灰石,使用磷酸三甲酯作为磷酸盐源获得了三个(PbApF,PbApCl,SrApCl)。非水溶剂的使用减轻了在水溶液中某些二价阳离子发生的磷酸氢盐的形成。甚至碱金属盐在许多溶剂中的有限溶解度也会产生非脂族复盐,例如NaPb4(PO4)3,NaPbPO4,KPb4(PO4)3,Cd(OH)NO3和NaBaPO4。
