An active and recyclable magnetic biobased heteropolyacid catalyst (HPW-MCMs) was prepared for the high yield of transesterification of Pistacia chinensis seed oil (PCO). The magnetic cellulose microspheres (MCMs) were used as the supporter, and the phosphotungstic acid (HPW) was synthesized in surface and micropores via in-situ reaction. Fourier transform infrared spectra (FT-IR), scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDX) and diffraction of X-ray (XRD) were fully used to characterize the catalyst. Furthermore, the conditions of 600 W of microwave power, 65 °C of temperature, 6 wt. % of catalyst amount, 8 of methanol/oil ratio and 30 min of reaction time were selected as the optimal conditions. Under the conditions, a high conversion of 96.6 % could be obtained. The HPW-MCMs could also be recovered conveniently and efficiently recycled for six cycles. Therefore, the prepared HPW-MCMs would be potentially useful for the efficient and economic transesterification reaction of PCO.

制备了一种可回收利用的磁性生物基杂多酸活性催化剂（HPW-MCM），以提高黄连木籽油（PCO）的酯交换率。磁性纤维素微球（MCM）被用作载体，并通过表面和微孔合成了磷钨酸（HPW）。原位反应。充分利用傅里叶变换红外光谱（FT-IR），扫描电子显微镜（SEM），能量色散X射线光谱（EDX）和X射线衍射（XRD）表征了催化剂。此外，微波功率为600 W，温度为65°C，重量为6 wt。选择催化剂量的％，甲醇/油比为8和反应时间为30分钟作为最佳条件。在此条件下，可获得96.6％的高转化率。HPW-MCM还可以方便，有效地回收六个周期。因此，所制备的HPW-MCM对于PCO的有效和经济的酯交换反应可能是有用的。
