found in the intracellular spaces and glands of plant tissue. The oils may be located throughout the entire plant‚ but are often concentrated in the seeds or flowers of the plant. Many of the essential oils are steam-volatile and can undergo steam distillation to isolate the oils. Another method of oil extraction from these plants is through both solvent extraction and pressing methods. The functional group that is mostly responsible for the characteristic odors and flavors of fruit and flowers is the

compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple or fractional distillation was the more efficient means of separating volatile compounds. Key Experimental Details‚ Observations

as a product. The product formed is separated through distillation. Because more than one alkene product can result from the reaction‚ Gas Chromatography is used to analyze the composition of the product mixture. IR spectrometry is also carried out to confirm the product. Procedure This experiment was carried out as described in Class Pak. The heat source power was set to 3 for fractional distillation and to 2 for simple distillation. For both processes‚ aluminum foil was wrapped around

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

In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

2. From the plots of the boiling point versus the volume of distillate in the simple distillation experiments‚ what can you conclude about the purity of your product? Product not very pure. No distinct line to know when one begins and one ends. Distillation of cyclohexane and toluene crossed over into the other’s range. Would need to perform more distillations to better purify the solvents. 5. What is the effect on the boiling point of a solution (e.g. water) produced by a soluble non-volatile

produce isopentyl acetate‚ banana oil. Acetic acid and isoamyl alcohol were used to synthesize isopentyl acetate. The techniques used for the separation and purification of isopentyl acetate were reflux‚ liquid-liquid extraction‚ neutralization and distillation. The identification of isopentyl acetate was based on boiling points and an infrared spectrum. This experiment resulted in a 11.68% yield. The reactants and products of this reaction are in equilibrium‚ and therefore it was difficult to obtain

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
