Effect of Calcination Temperature and Tmaoh on Catalytic Activity of Basic Clay

T.Y. Wibowo, A.Z. Abdullah and R. Zakaria

Montmorillonite K10 was intercalated with lithium hydroxide and used for the transesterification Methyl Laurate (ML) with glycerol. This modified clay was characterized to elucidate the influence of added Tetramethylammonium Hydroxide (TMAOH) on its catalytic activity. Effects of calcination temperature (350-650°C) on the catalytic properties of basic clay were investigated with the goal of determining the optimum pretreatment conditions. The basic clay calcined at 450°C exhibited the optimum activity when used together with TMAOH. The results showed that TMAOH played an important role in improving the efficiency of the basic clay. By using a glycerol/methyl laurate ratio of 8:1 without any addition of TMAOH at a temperature reaction of 130°C, 60.1% methyl laurate conversion and 56.5% selectivity to monolaurate were achieved over the LiK10 calcined at 450°C for 5 h. Meanwhile, the addition of TMAOH increased the ML conversion and selectivity to monolaurate to 82.5 and 88.2%, respectively.
