中文摘要：
采用浸渍法将磷钨酸（HPW）负载于六方介孔氧化硅（HMS）上,制备HPW改性HMS介孔材料HPW/HMS,对其进行了表征;以HPW/HMS为催化剂,催化2-萘甲醚（2-MN）与乙酸酐（AA）的酰化反应,考察了各因素对催化反应的影响.结果表明,HPW高度分散在HMS上,HPW/HMS的酸量和酸强度随HPW负载量增加而增加.在温度120℃、时间4 h、催化剂用量0.3 g及2-萘甲醚/乙酸酐摩尔比1：2条件下,2-萘甲醚转化率为75.3%（mol）,目标产物2-甲氧基-1-萘乙酮的选择性达83.0%（mol）.催化剂可回收再利用,催化活性略有降低.
英文摘要：
H3PW（12）O（40）·n H2O（HPW） supported on hexagonal mesoporous silica（HMS） was prepared via impregnation method to obtain modified mesoporous HMS（HPW/HMS）. The surface structure and acidty of the samples were characterised. The catalytic performance of HPW/HMS was tested through Friedel–Crafts acylations of 2-methoxynaphthalene（2-MN） with acetic anhydride（AA）. The results showed that the obtained HPW/HMS catalyst displayed a typical mesoporous structure. HPW was well dispersed on the HMS support, and the acidity increased with the amount of HPW loading. Under the conditions of 120 ℃, 4 h, HPW/HMS 0.3 g, molar ratio of 2-MN to AA 1：2, the conversion rate of 2-MN was 75.3%（mol） and the selectivity of the main product 2-methoxy-1-acetonaphthone was up to 83.0%（mol）. Repeated experiments demonstrated a slight decline in the catalytic activity.
