Its overall flavor profile relies heavily on clove and it could be said that all the other spices operate as background notes. Among the more prominent non-clove spices are cinnamon and nutmeg. The clove brings its peppery and camphor-heavy bitterness but is sweetened by the cinnamon and nutmeg. This spice blend can transform pancakes into a warm‚ sweetly aromatic treat that

Distillation Introduction: The recrystallization technique you learned last lab is a method for purifying solids. This week we will learn how to perform a distillation‚ a method for purifying liquids. Distillation is a common wet-chemical technique for separating organic compounds based on differences in boiling points. Upon heating a mixture of organic compounds‚ the more volatile compounds (those with the lowest boiling point) will vaporize first (i.e. be converted to gases)‚ leaving the higher-boiling

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

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

Experiment 16: Fractional Distillation of a Mixture CHM2210L Kelley Paul May 26‚ 2014 Tuesday Session: 50432 Abstract A distillation experiment was performed in attempt to separate two miscible fluids.This experiment used fractional distillation to separate ethanol from the azeotropic mixture of ethanol and water. The initial composition of the solution did not matter because the goal of the experiment was to distill the ethanol-water solution and obtain 95% ethanol in the distilled fraction

Simple and Fractional Distillation Experiment II Stancy Saji‚ 18 September 2014 Purpose Experiment II involved two kinds of distillation techniques: simple and fractional. Simple distillation was done to separate ethyl acetate—which has a usual boiling point of 77º—from a less volatile component‚ while fractional distillation was done to distinguish an ethyl acetate/n-butyl acetate mixture‚ which has boiling points of 77º and 125 º‚ respectively. Results and Discussion As previously stated the
