| Distillation is defined as: `Distillation is based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points.Therefore‚ when this vapor is cooled and condensed‚ the condensate will contain more volatile components. At the same time‚ the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently.Although many people have a fair idea what “distillation” means‚ the

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

Hold the gas collection tube at an angle as you fill it completely with tap water‚ until it is nearly overflowing. Holding the tube at an angle allows the air bubbles to escape. 6. Place the magnesium in the mouth of the gas collection tube so that it is about three cm below the surface of the water. Fold the thread extension over the side of the

molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate chemical substances in various types and sizes from microscopic to molecular level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane
