The same process of condensation is at work during distillation, which is essentially when a liquid is purified through temperature changes. One way to speed up this process is to use fractional distillation. Log in here for access. By heating a liquid to the temperature at which it turns into a vapor, it is separated from any possible impurities that are dissolved within it. Plot No. A variety of apparatuses are used, including retort stands, a burner, flasks, a thermometer, and a condenser. Also, if the temperature of the distillation suddenly changes, this usually indicates that one of the chemicals in your mixture has been removed. Once the liquid evaporates, it can be cooled over another container so that it condenses and accumulates again as a liquid. You might have also heard of distillation as the method to produce alcoholic spirits. 13, Old Post Office Lane, J. Step 7: When the thermometer stabilizes, the receiving glass should be swapped with a new one to ensure that the distillate that is being received is only the liquid which vaporizes at the temperature the thermometer reads. They include the following: This illustration shows the separate parts of a glass fractional distillation apparatus. When the liquid evaporates, many impurities are left behind, so they are not present in the distillate. Updates? Already registered? Since a perfect separation is never effected, the distillate is often redistilled to increase its purity (hence the expression double distilled or triple distilled). A-1301, BVR Ek Opp. Pune, Maharashtra, No. The refining process begins with the fractional distillation of heated crude oil. Those substances having a higher boiling point remain in the flask and constitute the residue. Fractional distillation is a slightly larger scale distillation process that involves the previously mentioned components, but must also include the fractionating column attachment.
