Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

How Modern Transport Fuels Effect our Environment Why is looking at alternate fuels important? There are several reasons‚ but the most important reason is that air pollution kills in the neighborhood of 3 million people every year and air pollution affects more than 1 billion people in a negative way. That ’s over 1/6 of the earths population being harmed by air pollution‚ that ’s a trend that cannot continue without extreme repercussions to everyone on the planet. Granted‚ air

Identification of a Conjugated Diene from Eucalyptus Oil Purpose: The purpose of this experiment was to prepare the Diels-Alder adduct of the unknown Conjugated diene in eucalyptus oil‚ to separate the adduct‚ and identify the unknown diene from the melting point of it¡¯s adduct. Introduction: This experiment was performed using techniques of heating under reflux‚ vacuum filtration‚ recrystallization‚ and melting point measurements. These techniques were used to separate the Diels-Alder

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

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

In the formation of acetylsalicylic acid (Aspirin)‚ salicylic acid and acetic anhydride were made to react in the presence of an acid catalyst‚ namely sulfuric acid. In the formation of methyl salicylate (oil of wintergreen)‚ salicylic acid and methanol were reacted together in the presence of the same acid catalyst‚ sulfuric acid. The designation of Part 1 for this experiment was used for the synthesis of Aspirin. To prepare the heating mechanism for the experiment‚ 250mL of tap water was

TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One

Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on differences in their
