Biodiesel was synthesized from soybean oil by transesterification over Li_2SiO_3 catalyst.The Li_2SiO_3 can be used for biodiesel production directly without further drying or thermal pretreatment,no obvious difference in the FAME conversion(92.4-96.7%) between the air-exposed catalyst(24-72 h) and the fresh one(94.2%).This leads to important benefits when considering industrial applications of Li_2SiO_3 as a solid catalyst for storing and handling catalyst without taking special actions.
