Biguanide-, imine-, and guanidine- based networks as catalysts for transesterification of vegetable oil
{{output}}
Polycationic systems based on poly(hexamethylene biguanide) (PHMBG), branched polyethyleneimine (PEI) and poly(N-vinylguanidine) (PVG) have been evaluated as heterogeneous catalysts for the transesterification of sunflower oil by methanol. Insoluble networks a... ...
