| Abstract: | A series of Li-Al hydrotalcite compounds with different n(Li)/n(Al) ratio was prepared via co-precipitation process.Resultant Li-Al hydrotalcite compounds were calcined at different temperatures to give their derivatives,Li-Al composite oxides.As-synthesized Li-Al composite oxides were used as solid alkali catalysts to prepare biodiesel via the transesterification of soybean oil and methanol,and the catalytic performance of the catalysts for the transesterification of soybean oil was investigated.It was fou... |
