LEWATIT® GF 101

Lewatit® GF 101 is a strongly acidic, macroporous, polymer-based resin in spherical bead form, with sulfonic acid groups. It is ideally 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.
