C. Thies, in Nanotechnology in the Food, Beverage and Nutraceutical Industries, 2012 8.6.1 High shear mixers. Rotor-stator and blade type blenders are examples of high shear mixers that function at atmospheric pressure.They are typically used to form pre-mixes or coarse dispersions that are subsequently converted into nanoemulsions or dispersions by more intense mixing …

Feb 01, 2013 After the addition, stirring in the cold was continued for 1 h followed by stirring at room temperature for 2 h. Evaporation of the chloroform (rotary evaporator) and subsequent recrystallization (methanol) of the residue affords the product in about 94.3% yield (mp 132.8C/1.013 bar).

Jan 27, 2012 The batch was concentrated on a rotary evaporator into a 1-L flask at about 30 C. The 10-L flask was rinsed to the evaporator as required with CH 2 Cl 2. Distillation was continued until it essentially stopped. The rotary evaporator was switched to a high vacuum source and evaporation continued about three hours at 35 to 40 C.

Jun 01, 2018 During the preparation of 2-Methyl-2-hexanol, the solution was poured into a 250ml round-bottom flask before the ether was removed on a rotary evaporator. The weight of the empty round bottom flask before the ether was removed was 41,50g and the weight of the round bottom flask with the product was 45,07g. The product yield therefore was 3,57g.

Jun 11, 2020 Methanol (30% of oil weight) and CH OK (1% of oil weight) are (3) Acid-catalyzed esterification. After acid washing, scum oil mixed with raw oil from the acid esterification at 60 C for 0.5 h. contains high amounts of FFA that were converted from The mixture is sent to a rotary evaporator to remove excess metha- soap.

May 01, 2020 After that, the crude extract was concentrated using a rotary evaporator. For antibacterial assay, the crude extract was subjected to partitioning by sequential extraction using increasing polarity solvents: hexane (Hex), chloroform (CHCl 3), ethyl acetate (EtOAc), and n-butanol (BuOH). The fractions were concentrated in a rotary evaporator. 2.2.

May 11, 2020 Attach the flask to a rotary evaporator and replace the heating bath with a dewar filled with acetone and dry ice (−78C). Rotate slowly to freeze the water inside the flask. Make sure that the volume of the flask is sufficient so that the volume of ice in the flask is less than half of the total volume to avoid cracks during freeze-drying ...

May 14, 2011 The slurry was filtered and the ethanolic extract obtained was dried with a rotary evaporator under reduced pressure at 313 K. The dried extract (98 g) was ground, dissolved in CH 3 OH, mixed with silica gel (118 g), and then dried in hot air oven at 333 K for one day. The sample was separated by using a wet column chromatographic technique.

This mixture was filtrated and the obtained filtrate was evaporated using a rotary evaporator at 40C until discarding the totality of ethanol. The obtained residue after evaporation under reduced pressure was partitioned following an increased gradient of polarity, with successively hexane, chloroform, ethyl acetate, and n-butanol (Figure 1 ).
