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。

Abstract: The main factors in the synthesis of layered zirconium phosphate phenylphosphonate Zr(PO4H)2-n(PO3Ph)nwere investigated. At F-/Zr4+=12 and H3PO4/Zr4+=20, a series of homogeneous Zr(PO4H)2-n(PO3Ph)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(PO4H)2-n(PO3PhSO3H)nhave abundant acidic sites and they are also stable below 300 ℃.

Key words: Zirconium phosphate phenylphosphonate, Synthesis, Thermostability, Sulfonation
