use | calcium methoxide, as an alkaline earth metal alkoxide, has the advantages of strong alkalinity, low solubility in methanol, long service life, etc., and can be used to catalyze transesterification to prepare biodiesel. |
preparation | calcium methoxide synthesis reaction: in a sealed reaction kettle, methanol is added dropwise to calcium carbide, where the molar ratio of calcium carbide to methanol is 1:2~6 to generate calcium methoxide. |
