Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

The Distillation of an Unknown Compound INTRODUCTION Distillation is the process heating a liquid to form vapor which is then collected when cooled and separated from the original liquid. The purpose of this experiment was to determine the identity of an unknown substance using simple and fractional distillation. Gas chromatography analysis the components of a mixture by separation of the materials by their different boiling points. EXPERIMENTAL The simple distillation apparatus was assembled

CHM 2210L-009 Experiment 1: Simple and Fractional Distillation of a Binary Mixture Aim: The aim of this experiment is to perform a simple and a fractional distillation and separate a mixture containing two liquids‚ cyclohexane and toluene. Post Lab: At any given temperature a liquid is in equilibrium with its vapor. This equilibrium is described by the vapor pressure of the liquid. The vapor pressure is the pressure that the molecules at the surface of the liquid

The coal tar obtained from coal by coking is also a mixture of hydrocarbons. Natural gas‚ petroleum‚ and coal tar are important sources of many hydrocarbons. These complex mixtures can be refined into simpler mixtures or pure substances by fractional distillation. During the refining of petroleum‚ one kind of hydrocarbon is often converted to another‚ more useful kind by cracking. Useful hydrocarbon mixtures include cooking gas‚ gasoline‚ naphtha‚ benzene‚ kerosene‚ paraffin‚ and lubricating oils.

DISTILLATION- SEPARATION OF A MIXTURE Ronald Ogbu‚ Alex 27th Aug. 2013 Purpose: To separate mixture of acetone and toluene using simple‚ packed and unpacked distillation columns. Results and Discussion: There were three distillation setups: simple‚ unpacked and pack fractional. All three procedures had different distillation apparatus but the unknown mixture was the same for all. The unknown liquid in a 50 ml round bottom flask was heated in a heating mantle such that a

RECRYSTALLISATION PRESNTED BY Mariam SeiduPriscilla TweneboahEvans Appiah-Kubi 3796509 Yaw Adu PokuEric Adjei 3809009 INTRODUCTION Recrystallization is a method of purifying a solid. There are two types of impurities: those more soluble in a given solvent than the main component and those less soluble. (If there are any impurities that have the same solubility as the main component‚ then a different solvent needs to be chosen.) When organic

alkene and water were produced and co-distilled into a collection vial. As in any distillation‚ unless precautions are taken‚ some of the product would have been lost as hold-up in the apparatus. Hold-up would result in a reduced yield of product. To overcome this problem and to ensure that a maximum amount of product is distilled‚ a higher boiling "chaser" solvent was added to the distillation flask and the distillation is continued until the temperature rose well over the BP of cyclohexene. At this
