以壳聚糖为原料，接枝氨基亚氨基甲磺酸，制备了胍基化壳聚糖（GCS）催化剂，用于豆油与甲醇的酯交换反应。采用傅里叶变换红外光谱、热重分析和X射线光电子能谱对GCS膜的结构和性能进行了研究。在催化剂用量为20 wt.%，甲醇/油质量比为2.5：1，在60 °C下搅拌6 h。结果表明，酯交换反应主要发生在催化膜表面。酯交换反应的动力学研究是根据拟均相模型进行的，并作为一级反应进行，活化能为76.95 kJ/mol，指前因子为7.94 × 109 min-1。
Guanidinylated chitosan (GCS), as a heterogeneous alkaline catalyst for the transesterification of soybean oil with methanol, was synthesized by grafting aminoiminomethanesulfonic acid onto chitosan. The structure and properties of GCS membrane were investigated by Fourier transform infrared spectroscopy, thermogravimetry and X-ray photoelectron spectroscopy. The soybean oil conversion reached 98.8% at the first run and 96.6% at the fifth run under the reaction conditions: catalyst amount of 20 wt.%, methanol/oil mass ratio of 2.5:1 at 60 °C for 6 h. Results show that the transesterification mainly took place on the surface of the catalytic membrane. The kinetics study of the transesterification was undertaken in terms of pseudo-homogeneous model and performed as a first order reaction with an activation energy of 76.95 kJ/mol and pre-exponential factor of 7.94 × 109min−1.
