| Lewatit® GF 101 is a strongly acidic, macroporous, polymer-based resin in spherical bead from, with sulfonic acid groups. It is suited as a heterogeneous catalyst for organic reactions. A large pore structure, high degree of crosslinking and good mechanical stability enable this catalyst to be used in polar and non-polar media. Lewatit Gf 101 is particularly suitable for the reduction of free fatty acids in triglycerides prior to transesterification to biodiesel. The free fatty acids are removed through esterification with methanol or ethanol to the corresponding esters.Information provided by Lanxess. |
