a total volume of approximately 51.2 mL. A steam distillation was performed‚ and about 28 mL of distillate was collected in the receiving flask. The distillate was added to a separatory funnel to perform an extraction with 5 mL of ethyl acetate. The ethyl acetate extract was then dried by adding 0.6102 grams of anhydrous calcium chloride to remove the water. The contents were filtered to remove the anhydrous calcium chloride from the ethyl acetate extract. This liquid contained the extracted limonene

Introduction: The purpose of this experiment is to derive Isopentyl acetate (banana oil) from the reaction of an alcohol and a carboxylic acid in a process called Fischer esterification (Fischer-Speier esterification). The name‚ banana oil‚ is due to banana odour released by formation of Isopentyl acetate. The alcohol and the carboxylic acid used in this experiment are Isopentyl alcohol and Glacial Acetic Acid. Both the overall reaction of Fischer esterification and the specific Fischer esterification

Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined that the unknown solid’s identity

Reaction Mechanism: Experimental Procedure To begin this experiment‚ a fractional distillation was set up in order to distill dicyclopentadiene. A 10 mL conical vial was filled with 5 mL of dicyclopentadiene and then heated to a steady boiling point (40-42 C). Cyclopentadiene was then placed on ice while

There are many methods by which this salicylaldehyde can be synthesized but one method with a relatively high yield starts with 2‚4-di-tert-butylphenol. The reaction scheme is shown below in Figure 1. 1 2 3 Figure 1: (1) 2‚4-di-tert-butylphenol ‚(2) 2‚4-di-tert-butyl-6-hydroxymethylphenol‚ (3) 3‚5-di-tert-butyl-salicylaldehyde shown above.

Ester water Particularly‚ 1-hexanol was reacted with an excess of acetic acid‚ using an acid catalyst to yield its ester: hexyl acetate. The reaction was performed under reflux which sped up the reaction by continuous vapor-condensation cycles of the solution mixture as the solution boiled. The vapors were blocked from escaping the solution by a stream of cold water running up the

Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism for this specific reaction was as follows:

The resulting dried product was recrystalized using hot ethyl acetate. A hot plate was used to boil ethyl acetate to be poured into a heating beaker with a mixture of EtoAc and adduct until the product dissolved. A sequential suction filtration completed this

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed
