采用一锅水热法合成了棒状CaxSiOx+ 2催化剂。采用550℃煅烧催化剂进行大豆油与甲醇的酯交换反应。在甲醇回流条件下，ca4sio6的FAME产率分别为82%和95%，反应时间分别为1和2 h。此外，不同CaxSiOx+ 2催化剂的FAME产率与其基本性质相关。此外，在ca4sio6催化剂上，室温下FAME收率可达80%左右。
Rod-like CaxSiOx+ 2catalysts were synthesized by using one-pot hydrothermal method. Catalysts calcined at 550 °C were used in the transesterification reaction of soybean oil with methanol. Under methanol reflux condition, FAME yields of 82% and 95% were achieved on Ca4SiO6in a reaction time of 1 and 2 h, separately. Also, the FAME yields on different CaxSiOx+ 2catalysts were correlated with their basic properties. Besides, a FAME yield of ca. 80% can be achieved under room temperature over Ca4SiO6catalyst.
