诸如异丙醇、叔丁醇这样一些工业生产中重要的二级和三级醇，还有乙醇，最常用的合适的制备技术是烯烃的催化水合。杂多酸的固态形式和液态形式都属于最强的酸，在醇类脱水反应中显示出良好的催化性能，在其逆向反应（水合反应）中也是很活泼的。最近，以杂多酸为催化剂的一些 Some of the important secondary and tertiary alcohols, such as isopropanol and t-butanol, which are industrially produced, as well as ethanol, the most commonly used suitable preparation technique is the catalytic hydration of olefins. Both the solid and liquid forms of heteropolyacid belong to the strongest acid and show good catalytic performance in alcohol dehydration reactions and are also very reactive in their counter-reactions (hydration reactions). Recently, heteropoly acid as a catalyst for some
