Chemical interesterification of rubber seed oil has been investigated for four different designed orifice devices in a pilot scale hydrodynamic cavitation (HC) system. Upstream pressure within 1-3.5bar induced cavities to intensify the process. An optimal orifice plate geometry was considered as plate with 1mm dia hole having 21 holes at 3bar inlet pressure. The optimisation results of interesterification were revealed by response surface methodology; methyl acetate to oil molar ratio of 14:1, catalyst amount of 0.75wt.% and reaction time of 20min at 50°C. HC is compared to mechanical stirring (MS) at optimised values. The reaction rate constant and the frequency factor of HC were 3.4-fold shorter and 3.2-fold higher than MS. The interesterified product was characterised by following EN 14214 and ASTM D 6751 international standards.
在中试规模的水力空化（HC）系统中，对橡胶籽油进行了四种不同设计的孔口装置的化学酯交换反应研究。在 1-3.5bar 的上游压力下，诱导空化来强化该过程。最佳孔板几何形状被认为是具有 3bar 入口压力下 21 个直径为 1mm 孔的板。通过响应面法对酯交换反应进行了优化；甲酯与油的摩尔比为 14:1，催化剂用量为 0.75wt.%，反应温度为 50°C，反应时间为 20min。将 HC 与机械搅拌（MS）在优化条件下进行比较。HC 的反应速率常数和频率因子比 MS 短 3.4 倍，高 3.2 倍。通过遵循 EN 14214 和 ASTM D 6751 国际标准对酯交换产物进行了表征。
