WebJul 1, 2024 · The purified glycerol sample, after being treated with bentonite at 60 °C for 75 min, was 89.5% glycerol, 4.3% water and 3.6% ash, with a density of 1.2212 g/mL. The cited authors concluded that activated bentonite could be used for the adsorption and removal of impurities from waste cooking oil. WebHerein, an optimized method for 100 g scale synthesis of glycerol oligomers using a microwave multimode source and the low priced K2CO3 as catalyst is reported. This method allows the complete conversion of glycerol to its oligomers in only 30 min, yielding molecular weights up to 1000 g mol−1. Furthermore, a simple iterative purification …
