A process to extract cholesterol from lanolin alcohol by selective solvent crystallization and recrystallization was developed. The crude lanosterol crystallization process was performed in methanol-acetone (3:1, v/v) as solvent at 18 mL g−1 liquid–solid ratio and 20.0 °C for 6 h. To be optimized by response surface methodology (RSM) coupled with central composite design, the process of cholesterol...
As a novel process intensification technology, microwave-assisted continuous reaction distillation (MRD) was proposed for the esterification reaction and separation of ethyl acetate (EtOAc). The effects of reflux ratio, mole ratio of acetic acid (HOAc) to ethanol (EtOH), reboiler duty, microwave power on EtOH conversions, EtOAc purity and mass ratio of distillate to feed (D/F) were explored. In comparison...
