tungstophosphoric heteropoly acid, Cs2.5H0.5PW12O40, is an active and environmentally friendly heterogeneous catalyst for the liquid-phase acetylation of nopol and several biomass-derived terpenic alcohols (i.e., α-terpineol, nerol, geraniol, linalool, menthol, isoborneol, perillyl alcohol, carveol, isopulegol, carvacrol and nerolidol) with acetic anhydride. The resulting flavor and fragrance acetic esters, which
钨磷杂多酸铯盐Cs 2.5 H 0.5 PW 12 O 40是一种活性且对环境友好的非均相催化剂,可用于诺普乐和几种生物质衍生的萜烯醇(即,乙-松油醇,神经醇,香叶醇,芳樟醇,薄荷醇,异冰片醇,紫苏醇,香芹酚,异胡薄荷醇,香芹酚和橙花醇)与乙酸酐。得到的香料和芳香族乙酸酯以良好或优异的收率获得了广泛用于香料,家用和食品中。该反应在室温下以较低的催化剂负载量进行而没有大量的催化剂浸出,并且可以在无溶剂的系统中以化学计量的乙酰化剂进行。
