    How Carboxylic Acids and Alcohols React to Produce Esters: Esters and Ester Production: Esters are abundant and ever present‚ and are the chemical basis of almost all fatty acids and oils. Small esters are responsible for the aroma of fruits‚ perfumes and‚ by extension‚ wines and other alcohols. Esters are formed when a carboxylic acid and an alcohol chemically combine‚ losing a molecule of water in the process. Carboxylic acids are organic molecular compounds that form a homologous series

From least polar to the most polar: Heptane-Toluene-Acetone-Methanol-Acetic acid ‚ ‚ ‚ ‚ 4. The Rf (Retardation factor) is the ratio of the distance that the compound/mixture traveled to the distance the solvent/mobile phase traveled. 5. From least Rf to the highest Rf: Benzoic acid – Benzaladehyde - n-Decane If the TLC were run with a more polar solvent‚ all the

    not explored in this laboratory. This experiment explores these techniques to identify an unknown amino acid by TLC and analyze food colors using paper chromatography. By using 2.0 mL of dimethoxyethane and 18 mL of absolute ethanol as the developing solution‚ and then spotting each sample of amino acids and an unknown on the silica gel chromatography plate‚ we began the process of TLC plating. The ninhydrin solution was sprayed on the chromatography plate and allowed to dry. After allowing the solution

    Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters

    IDENTIFICATION OF UNKNOWN SOLUTIONS USING TLC CHROMATOGRAPHY Purpose: To become familiar with the principles and terminology of TLC chromatography to identify an unknown molecule based on comparisons with known laboratory standards and Rf factors. Background Thin Layer Chromatography: Chromatography is a sophisticated method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that

    chromatography (TLC) is an extremely valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles behind it. TLC is normally

    In this TLC lab‚ we explored the relative polarities of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen‚ and Caffeine based on their functional groups. The most overall polar analgesic is considered to be the analgesic that contained the most polar function groups. The amine and amide functional groups are the most polar. In this experiment‚ we found that both these functional groups are found in Caffeine. As a result‚ Caffeine was the most polar out of Acetylsalicylic Acid‚ Ibuprofen‚ Acetaminophen
