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

UNIVERSITY OF THE GAMBIA LECTURE NOTES COURSE: PRINCIPLES OF CHEMISTRY II (ORGANIC CHEMISTRY) CODE: CHM 161 2ND SEMESTER SESSION: 2012/2013 LECTURER: ANTHONY F. ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements

The spices in Ancient Egypt‚ the pyramids contained hieroglyphs demonstrating various uses of spices. Spice trade in the Bible‚ Solomon’s acquaintance‚ the Queen of Sheba brought camels laden with spices‚ around 1900 BC Joseph’s brothers sold him to a roving spice trade caravan.

samples that we are going to analyze are: the EtOAc from Simple distillation‚ the Fraction 1‚ Fraction 2‚ and Fraction 3 from the Fractional Distillation. Experimental Procedure 1. Inject a 5 µL sample of EtOAc from the Simple Distillation. Determine the actual % recovery of the purified EtOAc based on the % composition observed from the gas chromatogram. 2. Inject a 5 µL sample of Fraction 1 from the Fractional Distillation. Determine the actual % recovery of the purified EtOAc based

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

In one of the studies‚ the effect of cinnamon was studied against numerous organisms such as fungus like Aspergillus flavus‚ yeast species such as Candida lipolytica‚ Mucor plumbeus and Staphylococcus aureus. Its combination along with clove oil has been impressive and effective against A. flavus. The cinnamon oil has antimicrobial action in the range 10-150 μg ml − 1. Another intriguing fact about cinnamon is its role in altering or changing the expression of a gene icaA

July 14‚ 2009 Experiment 6: Fractional Distillation. Separation of Petroleum Hydrocarbons Abstract: A mixture of cyclohexane and toluene were separate from one another by fractional distillation in order to measure the composition of each fraction and prepare the sample for gas chromatography. Introduction: Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application
