摘　　要：研究了制备苯膦酸－磷酸锆Ｚｒ（ＰＯ４Ｈ）２－ｎ（ＰＯ３Ｐｈ）ｎ的主要影响因素．在Ｆ－／Ｚｒ４＋＝１２和Ｈ３ＰＯ４／Ｚｒ４＋＝２０条件下，通过改变苯膦酸用量获得了ｎ＝０～２的系列单一晶相层状苯膦酸－磷酸锆，其热稳定性达４００℃以上．苯膦酸－磷酸锆的磺化试验表明层间苯环可被完全磺化，磺化产物Ｚｒ（ＰＯ４Ｈ）２－ｎ（ＰＯ３ＰｈＳＯ３Ｈ）ｎ具有丰富的酸性位，其热稳定性亦可达到３００℃以上．The main factors in the synthesis of layered zirconium phosphate phenylphosphonate Zr(PO 4H) 2- n (PO 3Ph) n were investigated. At F -/Zr 4+ =12 and H 3PO 4/Zr 4+ =20, a series of homogeneous Zr(PO 4H) 2- n (PO 3Ph) n ( n =0￣2) were synthesized by changing the amount of phenylphosphonic acid. The crystals are thermally stable below 400 ℃. The phenyl groups in the layered structure can be sulfonated almost quantitatively. The sulfonated products Zr(PO 4H) 2- n (PO 3PhSO 3H) n have abundant acidic sites and they are also stable below 300 ℃.
