CHEM 3152-003 Experiment 2: Fractional Distillation and Gas Chromatography Introduction: The purpose of this experiment was to separate a mixture of ethyl acetate (EtOAc) and toluene by using the method of fractional distillation and to analyze the fractions using gas chromatography (GC). ethyl acetate toluene Distillation is a method known as separating or purifying a liquid or mixture by vaporization and condensation. In a simple distillation‚ the liquids being separated boil below 150 0C

Fractional distillation was used in this experiment. This is one of two ways for distillation‚ the other being simple distillation. However‚ with a simple distillation‚ the difference of boiling points between the substances must be more than 40 to 50 degrees C. A fractional distillation column is needed in a fractional distillation. The column in a fractional distillation column provides a temperature gradient where the temperature is lower at the top of the column and the temperature is greater

The process of distillation is commonly used to purify liquids. The process of distillation allows separation of distillates based on the temperatures at which they boil. Liquids with higher volatility boil at lower rates than liquids that are less volatile. Because of this when a mixture of two substances is created there will be a spike in the boiling point. At the spike the more volatile substance has vaporized and condense out of the mixture leaving the less volatile liquid. Thus the temperature

Chem 2203 Sec 026 27/September/2013 Experiment 3B: Fractional Semi-microscale Distillation Separation of Hexane and Toluene. Objective: The main goal of this lab is to learn how separation of binary liquid mixtures is performed. Especially when the two liquids have boiling points varying by about 30° C. Hexane can be separated from toluene in this experiment because of the difference in their boiling points. Since toluene has a higher boiling point‚ it will left at the bottom while the hexane

Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are

Experiment 1: Simple and Fractional Distillation of a Binary Mixture Introduction: In this experiment the aim is to separate two chemicals from a stock mixture (azeotrope) using two different distillation processes. In both methods (simple and fractional) the liquids reach a boiling point‚ the molecules then vaporize‚ separate from the stock mixture and then condense back into liquid form down the to the receiver. Simple distillation works well when the two components boiling points have a large

Separations of the Components of a Mixture January 9‚ 2013 Hailey Rounds Partners: Kelsy Shay Katie Nelson Objectives: The purposes of this experiment are to separate two components in a mixture‚ specifically sodium chloride and silica‚ and find the correlating percent composition of each. Abstract: This experiment consisted of the separation of sodium chloride and silica. The mixture was separated by extracting the sodium chloride with water and drying both substances. Adding water to

The Separation of a Liquid Mixture by Simple Distillation Objective The purpose of doing this experiment is to separate two miscible liquids samples of cyclohexane and toluene using simple distillation. The objectives will be to record boiling range and volumes (mL) of distillates that are attained during the process of distillation. Background Distillation is a frequently used technique for separating mixtures based on differences in the boiling points of components in the mixture. The

Introduction: The objective of this experiment is to become familiar with the methods of separating substances from one another using decantation‚ extraction‚ and sublimation techniques. Most materials in our surroundings are mixtures of two or more substances in which each substance retains its own chemical identity and therefore its own properties. Mixtures are either homogeneous or heterogeneous. Mixtures that don’t
