摘要
运用ＸＲＤ，ＥＳＲ方法研究了萘氧化制苯酐催化剂中Ｋ２ＳＯ４助剂含量对催化性能的影响。
The influence of the content of K 2SO
4 promoter on the catalytic properties in the oxidation of naphthalene to phthalic anhydride has
been studied by the methods of XRD and ESR The reason that more K 2SO 4 content will
decrease the selectivity for phthalic anhydride is explained.
