Acetic acid

smelling products. The process for making air fresheners uses Fischer Esterification, the same procedure used to create our ester (Banana oil). Creating an artificial ester involves using various molecules containing alcohol groups (OH) and carboxylic acid groups (C=OOH), using different combinations will create different pleasurable scents. The chemical reaction is an equilibrium reaction, meaning that at the reactions termination there are often non-reacted reactants remaining in the…

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…

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…

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…

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…

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…

p-toluenesulfonic acid (APTS) led to the formation of 3,5-disubstituted-1,2,4-oxadiazoles 4a-f in good yields (51‒70%). The acidiccleavage of the menthone chiral auxiliary30a-d in 4c-e was achieved by acetolysis, in a mixture of Ac2O/AcOH and with a catalytic amount of H2SO4. After neutralization with 5M NaOH added dropwise, the methylamide-isoxazolidines 5c-d were obtained in 60 and 57% yields, respectively, from 4c-d, while the N-acetyl-methylamide-isoxazolidine 5e was obtained in 68% yield…

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…

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…
