EXPERIMENT 2: BATCH DISTILLATION AT CONSTANT REFLUX OBJECTIVE: To operate a batch distillation unit at constant reflux. To examine the change in top and bottom composition over time in a batch distillation. PROCEDURES: 1. Perform the general start-up procedures (Section 4). Refer appendix 1. 2. Record initial volume and refractive index of the liquid mixture in the reboiler. 3. Set the heater power to 1.5kW. 4. Set reflux timer to 10 second for set 1 and 30 second for set 2. ( Note: Set 1:

students to familiarize and perfect the simple distillation method to produce 4-Methylcyclohexene and to gain experience using an IR spectroscopy to characterize the product of the reaction in favor of equilibrium. B. Results and Discussion: C. Experimental: 24 mL of 4-methylcyclohexanol‚ 5mL of phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer. A simple distillation set up was installed with a 250mL round

Experiment D: Separation of Alcohols by Fractional Distillation Pre-lab Properties: Propanol‚ butanol‚ methanol Purpose: To separate two alcohols by distillation and analyze results with GC. Do not plug mantle directly into electrical outlet‚ use controller! Use 40/60 mol percent propanol/butanol (no cyclohexane or toluene are used in this lab because they are more toxic) Set up fractional distillation Set heat at highest level to start‚ then turn back down to 60-80% when vapor starts up column

One major observation made throughout this experiment was during the steam distillation. As the steam distillation started and the solution in the flask began heating‚ it was clear that too much stopcock grease was used around the glassware. The grease from the connecting ends of the three way connecting tube was melting and seeping into the clove and water solution in the two necked round bottom flask. The solution in the flask was immediately discarded and repeated with clean glassware and a very

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

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 product obtained by distillation‚ is termed

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

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity
