The hydration and isomerization of the biomass turpentine have been studied in the presence of Purolite CT175. The ion exchange resin catalyst was active for hydration and selective for producing terpenic alcohols, with a conversion of 97% and showed 57% selectivity for α-terpineol using heating and stirring. The Purolite CT175-catalyzed isomerization of turpentine taken place in a high intensity ultrasound (HIU) condition; and showed conversion of 90% and 30% selectivity for camphene at 30 min. Recyclability of ion exchange resin was evaluated in both reaction and its activity remained good even after four runs.

生物质转化：使用离子交换树脂作为催化剂的松节油的水合和异构化反应

已经在Purolite CT175的存在下研究了生物质松节油的水合和异构化。离子交换树脂催化剂具有水合活性，并选择性地生产萜烯醇，其转化率为97％，并通过加热和搅拌显示对α-萜品醇的选择性为57％。Purolite CT175催化松节油的异构化反应是在高强度超声（HIU）条件下进行的；并显示30分钟时对camp烯的选择性转化率为90％和30％。在两个反应中均评估了离子交换树脂的可回收性，即使经过四次运行，其活性仍保持良好。
