Catalysts of Cu(II) and Co(II) adsorbed in chitosan was used in transesterification of soy bean and babassu oils. The catalysts were characterized by infrared, atomic absorption and TG, and biodiesels was characterized by infrared, NMR, CG, TG, physic chemistry analysis. The maximum adsorption values found for copper and cobalt cations were 1.584 and 1.260mgg(-1), respectively, in 180min. However, conversion of oils in biodiesel was better when used Co(II) adsorbed in chitosan.
吸附在壳聚糖中的铜（II）和钴（II）催化剂用于大豆油和巴巴苏油的酯交换反应。通过红外光谱、原子吸收光谱和热重分析对催化剂进行了表征，通过红外光谱、核磁共振、气相色谱、热重分析和物理化学分析对生物柴油进行了表征。在180分钟内，铜和钴阳离子的最大吸附值分别为1.584和1.260mg g⁻¹。然而，使用吸附在壳聚糖中的钴（II）时，油转化为生物柴油的效果更好。
