Jan 01, 2022 After that, water from the catalyst mixture was evaporated using a vacuum rotary evaporator, and the resulting solid was calcined at 350 C temperature in a furnace. The corresponding catalysts were denoted as EPTN-1 (10 wt% HPW), EPTN-2 (20 wt% HPW), EPTN-3 (30 wt% HPW), and EPTN-4 (40 wt% HPW) based on the quantity of parent HPW loading.

Mar 05, 2020 To separate the two, use a rotary evaporator. When connected to a vacuum pump, the rotary evaporator uses the vacuum to lower the boiling point of ethanol, resulting in a quicker evaporation. The resulting extract or oil will be completely free of ethanol. This process also allows ethanol to be recovered for additional extractions.

Rotary evaporators, commonly known as rotavapors, rotavaps or rotovaps, are extremely valuable to a number of downstream applications requiring efficient distillation solvent removal.Often combined with a vacuum pump, rotary evaporators are used to remove solvents from samples through evaporation. During this process, rotary evaporators reduce the …

Sep 27, 2021 Be sure to first cool the aqueous solution in an ice bath before extraction if the acidification created noticeable heat. Follow up with a brine wash (\(\times 1\)) if using diethyl ether or ethyl acetate, dry with a drying agent, and remove the solvent via rotary evaporator to leave the pure acidic component. Isolating the Basic component:
