中文摘要 | 一般工業製程常用之酸性觸媒為H2SO4;HF及AlCl3等,雖可成功地應用於煉油;石化及特化等催化製程,但皆有其不易克服之困難,如HF具有毒性,AlCl3有廢鹼液處理問題,H2SO4則有設備腐蝕及廢酸處理問題,因此工業界乃努力尋求其它固態酸觸媒,期能取代傳統使用之酸觸媒,其中分子篩在煉油及石化工業上廣泛被應用,但仍無法取而代之。異多體酸(HPA)及其鹽類觸媒除可克服腐蝕及污染問題之外,又能保持低溫活性之優點,尤其是負載型觸媒之製備與應用方面,已有相當重要之進展,應可成為新一代之固態酸觸媒。本研究主要是探討負載型磷鎢異多體酸之製備方法,對晶體結構及2-丁醇與醋酸之酯化反應活性之影響。 |
英文摘要 | The acidic catalysts H2SO4, HF, and AlCl3 have been used successfully for a lot of catalytic processes in the refining, petrochemical and speciality chemical industries. However, the toxic pollution of HF, caustic waste treatment of AlCl3, and facility corrosion of H2SO4 are still the remain problems to be overcomed. Recently, some of the solid acid or superacid catalysts were developed for the replacement of conventional liquid acid catalysts. The utilization of solid acid catalyst brings the improvement in corrosion and environmental problems. However, it also diminishes the benefit of higher activities from liquid acid catalyst. For the consideration of homogeneous and heterogeneous acid catalysis, heteropoly acid (HPA) and its salt could be used in the industrial acidic catalytic processes, and the recent progress in supported HPA catalyst makes it to be a potential solid acid catalyst in the future. The effects of preparation method on the esterification of s-butanol and acetic acid were studied in this paper. |
