杂多酸催化剂的催化影响因素及应用

Influencing Factors and Application of Heteropoly Acid Catalyst

文章阐述了杂多酸催化剂的催化影响因素及应用。杂多酸具有较强的催化活性,同时也具备酸性与氧化还原性。不用载体、不同温度焙烧、不同的酸酸化都对杂多酸催化效果有着不同影响。杂多酸催化剂在催化水合反应、酯化反应、烷基化反应中有广泛的应用。作为一种环境友好型催化剂,它既能保持低温高活性、高选择性的优点,又能克服酸催化反应的腐蚀污染问题,而且可以重复使用,具有广阔的应用前景。

In this paper,the influence factors and application of heteropoly acid catalyst are reviewed.HETEROPOLY ACID has high catalytic activity,acidity and oxidation-reduction.No support,calcination at different temperature and acidification have different effects on the catalytic effect of heteropoly acid.Heteropoly acid catalysts are widely used in hydration,esterification and alkylation reactions.As an environment-friendly catalyst,it can not only keep the advantages of low temperature,high activity and high selectivity,but also overcome the corrosion pollution of acid catalytic reaction.
