Show More
In this lab, benzoic acid, benzocaine, and 9-fulorenone are isolated from a three-component mixture by using the acid-base extraction and other following types of various extraction techniques.
An acid-base reaction is utilized in order to isolate the individual species from the mixture. First, in isolating the base benzocaine, proton transfers occurred via reaction with hydrochloric acid, which led to a significant shift in the polarity of the said compound, although the conjugate acid of benzocaine formed as a result. Due to the change in polarity, the state of benzocaine shifted from being solubilized in diethyl ether to water. Through vacuum filtration, water was removed. Sodium hydroxide was added to the separated water in order to produce

    9-Fluorenone Lab Report

    Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are commonly used in chemical reductions.…

    6.03 Calorimetry Lab Report

    A graduated cylinder was used to measure 200mL of distilled water into an Erlenmeyer flask and then 40mL of 0.6 M NaOH was added to the distilled water in the flask. The flask was then plugged with a rubber stopper and shook in order to mix the solution. A buret was then washed, rinsed with distilled water, and then 5 mL of the NaOH diluted solution. After the cleansing of the buret, it was then filled up with the NaOH diluted solution. The dilution of the solution was calculated to find the molarity of the NaOH.…

    Exo And Endo-Norborneol Reaction Lab Report

    The neutralization of the reaction was verified using pH paper to test whether the pH was neutral or slightly basic. At this point, the two possible products in the round bottom flask could have been exo- and endo-norborneol. Extraction and washing was performed and the exo- and endo-norborneol products formed were extracted into dichloromethane due to their similar solubilities, where the two products are overwhelmingly non-polar despite the one hydroxyl group. The dichloromethane (DCM) was the bottom layer formed, while the aqueous layer, the layer that was washed away, was the top and this was due to the weight of the chlorine atom that made DCM more dense. Extraction was repeated several times due to the partition coefficient, as it theorizes how smaller extractions are better than bigger extractions because they yield more concentrated extractions in the end.…

    Unidentified Compound Lab Report

    Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a couple preliminary tests, which include physical state and smell.…

    Discussion and Scientific Explanations The main goals of this experiment was to find the unknown compound, to discover the compounds chemical and physical properties and create two synthesis of the compound and compare the two compounds. We found out our compound was ionic because the compound dissolved in water, but not in toluene or acetone by using a solubility test, results on Table 1 of the group lab report. On page 59 of the Cooperative Chemistry Laboratory Manual is a chart on suggested liquids and the inference if the compound is soluble [1]. When then checked the pH of the solution by using pH strip. The solution had a pH>7.…

    Unknown Compounds

    Given an unknown compound in container 3, solubility tests, cation tests, anion tests, and conductivity tests can be used to determine the various properties of the unknown to then make a positive identification of the unknown. These results will not only show chemical and physical properties but also what the unknown compound might react with to form other compounds. After performing the four anion tests, a positive identification was able to be made showing that the unknown compound contained a chloride ion since a white precipitate was formed from the reaction (Table 1). The sulfate, nitrate, and carbonate tests all yielded negative results when no precipitate was formed. The reaction of the chloride anion is as follows: Cl-…

Krasner Professor Garfield Beckford CHEM 1211 L 25 September 2015 Lab Report Concerning Acid-Base Titrations The purpose of this experiment was to recognize the procedures for conducting acid-base titrations. Each acid-base titration used one solution to analyze another; it also involved the use of an indicator, which denoted the endpoint of the titration. The indicator used was phenolphthalein; it produced a pink hue when the titrations reached their endpoints – between pH 8 and pH 10.…

    P Toluidine Synthesis Analysis

    Benzocaine was synthesized from p-toluidine in a four step synthesis. Each intermediate product, including N-acetyl-p-toluidine, p-acetamidobenzoic acid, and p-aminobenzoic acid, was checked for yield, presence, and purity through weighing, taking IR and NMR spectrums, and determining the melting point. Thin Layer Chromatography was used to ensure the completion of the final reaction from p-aminobenzoic acid to benzocaine. The yield of the first step from p-toluidine to N-acetyl-p-toluidine was 91.9%. The yield of the second step from N-acetyl-p-toluidine to p-acetamidobenzoic acid was 49.85% The yield of the third step from p-acetamidobenzoic acid to p-aminobenzoic acid was 32.49%, which was not enough to continue so some product was borrowed…
