正丁烷氧化制顺酐V-P-O催化剂前驱物研究进展

Progress in study of the precursors of V P O catalysts for oxidation of n butane to maleic anhydride

介绍了５种Ｖ－Ｐ－Ｏ催化剂前驱物ＶＯＰＯ４·２Ｈ２Ｏ、ＶＯ（Ｈ２ＰＯ４）２、ＶＯＨＰＯ３·１．５Ｈ２Ｏ、ＶＯＣｎＨ２ｎ＋１ＰＯ３·ｘＨ２Ｏ、ＶＯ（Ｈ２ＰＯ３）２的研究进展，评述了它们的特性，为Ｖ－Ｐ－Ｏ催化剂进一步发展提出了展望。

A brief account is given of the recent progress in study of five precursors, VOPO 4·2H 2O, VO(H 2PO 4) 2,VOHPO 3·1.5H 2O, VOC nH 2n+1 PO 3·xH 2O,and VO(H 2PO 3) 2, of V P O catalysts for oxidation of n butane to maleic anhydride. The Characteristics of the precursors are discussed and further development of V P O catalysts are prospected.
