Distillation - Wikipedia

Distillation - Wikipedia

A simple set-up to distill dry and oxygen-free toluene. Diagram of an industrial-scale vacuum distillation column as commonly used in oil refineries: A rotary evaporator is able to distill solvents more quickly at lower temperatures through the use of a vacuum. Distillation using semi-microscale apparatus.

Consider Water (H 2 O) for an example. One mole of water is 18.0152 grams. In that compound, there are two moles of H atoms and 2 x 1.008 = 2.016 grams. That’s how many grams of hydrogen are present in one mole of water. There is also one mole of oxygen atoms weighing 16.00 grams in the mole of water.

Jan 25, 2014 To this, 20 L of linoleic acid and 200 mg of Tween-40 emulsifier were added. Then the mixture containing chloroform solvent was completely removed by vacuum using a rotary vacuum evaporator at 45 C. For the formation of emulsion, 50 mL of oxygenated distilled water was slowly added to this semi-solid residue and shaken vigorously.

The fractions of 22 min to 40 min are collected in a 200-mL pear-shaped flask and concentrated to 0.5 mL on a rotary evaporator at 40 C. Evaporate it to dryness using a nitrogen evaporator. Dissolve residues with 1.0 mL acetonitrile + water (3 + 2) and pass through the 0.20-μm filter membrane. The solution is ready for LC-MS-MS determination.
