  • Acetone And Iodine Reaction Lab Report

    slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable elementary steps that would otherwise not exist without its presence. In addition, a catalyst does not get used up in the reaction. In this case, hydrochloric acid reappears in the products of the reaction…

  • Case Study: Isolation And Proliferation Of MSC

    concentration of 0.075%) was added and incubated for 1h. The supernatant was discarded and the cells in 96-well plates were washed with PBS twice to remove the neutral red that was not phagocytized by macrophages. Then cell lysate (ethanol and 0/01 % acetic acid at the ratio of 1∶1, 200 µl/well) was added to lyse cells. After cells were incubated at 4℃ overnight, the optical density at 490 nm was measured by a microplate reader. 2.6. Phagocytosis Assay by opsonized heat-killed baker's…

  • Acetaminophen Synthesis Lab Report

    analysis to determine the unknown alcohols used to produce the esters. Acetaminophen, a popular active ingredient in many over-the-counter drugs, is used as a pain reliever and a fever reducer. It is synthesized from the reaction between a carboxylic acid and an amine; thus, acetaminophen contains hydroxyl and amide functional groups.1 C6H7NO + C4H6O3 C8H9NO2 + C2H4O2 This reaction is commonly known as a condensation reaction. A condensation reaction is a chemical reaction where two reactants…

  • Tetrahydrocarbazole Synthesis Lab Report

    compounds naming tetrahydrocarbazoles having the significant biological properties. The newly substituted tetrahydrocarbazole derivatives were prepared from substituted phenylhydrazine and cyclohexanone in glacial acetic acid under reflux. These intermediates on reaction with substituted aromatic acid chlorides in alkaline media finally converted to N-Substituted tetrahydrocarbazoles. Fifteen compounds are synthesized and charaterized by their melting point (MP), IR, NMR, MS and elemental…

  • Ester Synthesis Lab Report

    esterfication is the technique used in order to synthesize isopentyl acetate. This type of esterfication involves the reaction between a carboxylic acid and an alcohol in the presence of an acid catalyst. The esterfication mechanism in this experiment involves the reaction between glacial acetic acid and isopentyl alcohol with sulfuric acid…

  • Extraction Process Analysis Essay

    2.2. Extraction process analysis The solvent is fed from the bottom and broth from the top since the mass separation agent or solvent has a lower density than the aqueous mixture. The raffinate phase contains most of water and traces of HAc, and solvent, whereas the extract phase includes most of the solvent, HAc, and traces of water. The amount and composition of the mixed solvent significantly important for the process economy because it directly affects the composition of HAc in the extract…

  • Esters Lab

    oxygen (Clark, 2004). The single bond oxygen is bonded to another carbon. Esters can be produced through various synthetic routes. Since, esters are produced from mixing carboxylic acids and alcohols, they can synthesized artificially in labs. One possible way to synthesized esters is to react an alcohol and a carboxylic acid. The purpose of this lab was to observe the synthesis of esters and identify the odor of each ester synthesized. The procedure to…

  • Carboxylic Acid Synthesis Lab Report

    Purpose: As derivatives of carboxylic acids, esters are abundant compounds that often contribute to the fragrances in flowers, fruits, and coffee. Esters are synthesized from either organic or inorganic acids through a process called esterification. In this reaction, a carboxylic acid (RCOOH) and an alcohol (R’OH) mix in the presence of a strong acid catalyst to form a neutral, water-insoluble ester (RCOO’R) that gives off a pleasant smell. The following is an example of this reaction: The…

  • Synthesis Of P-Benbenediazonium Chloride Lab Report

    Introduction: Nitrous acid (HNO2) is used as a source of nitrosonium ion (N≡O+). The nitrosonium ion by reacting with an aromatic amine converted into a diazonium salt. As diazonium ion is a weak electrophile, it reacts with electron-rich, aromatic coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red…
