Why is the conversion of ethanol to ethanoic acid and oxidation reaction

In the conversion of ethanol to ethanoic acid, a very strong oxidizing agent alkaline potassium permanganate is used which donates oxygen to the ethanol to form ethanoic acid. Since the addition of oxygen to a compound is termed as oxidation, this reaction is considered as an oxidation reaction. In this process, the oxidizing agent used is alkaline potassium permanganate.

\( \newcommand\) bonds to the hydroxylic carbon, are oxidized only with accompanying degradation into smaller fragments by cleavage of carbon-carbon bonds. secondary alcohols tertiary alcohols Industrial Oxidation of Alcohols Conversion of ethanol to ethanal is carried out on a commercial scale by passing gaseous ethanol over a copper catalyst at \(300^\text\) conversions of \(20\%\)-\(50\%\) per pass can be realized and, by recycling the unreacted alcohol, the yield can be greater than \(90\%\). Another commercial process uses a silver catalyst and oxygen to combine with the hydrogen, which makes the net reaction substantially exothermic: In effect, this is a partial combustion reaction and requires very careful control to prevent overoxidation. In fact, by modifying the reaction conditions (alcohol-to-oxygen ratio, temperature, pressure, and reaction time), the oxidation proceeds smoothly to ethanoic acid: Reactions of this type are particularly suitable as industrial processes because they generally can be run in continuous-flow reactors, and can utilize a cheap oxidizing agent, usually supplied directly as air. Chromic Acid Oxidation Laboratory oxidation of alcohols most often is carried out with chromic acid \(\left( \ce\) reagent is soluble in chlorinated solvents such as dichloromethane, and the resulting solutions rapidly oxidize to at ordinary temperatures: The yields usually are good, partly because the absence of strong acid minimizes degradation and rearrangeme...

The conversion of ethanol to ethanoic acid involves the removal of the Hydrogen atom and the addition of oxygen (oxidation reaction). In the first step, the Hydrogen molecule is removed from ethanol to form ethanal. Since Hydrogen loss is oxidation so, the reaction is an oxidation reaction. Similarly an oxygen atom is added to form ethanoic acid from ethanal. As, the gain of Oxygen is called oxidation. So, the reaction is an oxidation reaction.

Why is the conversion of ethanol to ethanoic acid considered an oxidation reaction? Write the oxidising agent used in the reaction involved. Answer The conversion of ethanol to ethanoic acid is considered an oxidation reaction because oxygen atoms are added to ethanol to convert it to ethanoic acid . The following reaction takes place:

The experiment is most appropriate for post-16 students.This is a straightforward class experiment that will take about 10 minutes. Equipment Apparatus • Goggles • Boiling tube (note 1) • Dropping pipette • Test tube rack • Test tube holder • Bunsen burner • Heat resistant mat Chemicals • Ethanol (IDA, Industrial Denatured Alcohol) (HIGHLY FLAMMABLE, HARMFUL), 2–3 cm 3, provided in small bottles • Acidified sodium dichromate(VI) solution, 10 cm 3(VERY TOXIC, CORROSIVE)(note 2) Equipment notes • A large, 150 x 25 mm, test tube. • Student should be provided with the acidified dichromate(VI) solution already prepared as described here. Wearing goggles (or a face shield), prepare the solution by completely dissolving 25 g of sodium dichromate(VI)–2–water (Na 2Cr 2O 7.2H 2O) in 75 cm 3of water in a beaker or conical flask. Slowly and carefully add 10 cm 3of concentrated sulfuric acid and mix thoroughly. Provide this solution in small, appropriately labelledbottles with pipettes. Students should be instructed in the safe use of this solution. Health, safety and technical notes • • Wear goggles. • Ethanolor IDA (Industrial Denature Alcohol), C 2H 5OH(l),(HIGHLY FLAMMABLE, HARMFUL) – see CLEAPSS Hazcard HC040a. • Acidified sodium dichromate(VI) solution,Na 2Cr 2O 7(aq) (VERY TOXIC, OXIDISING, DANGEROUS FOR THE ENVIRONMENT)– see CLEAPSSHazcard HC078c and note 2. • Concentrated sulfuric acid, H 2SO 4(l)(CORROSIVE)– see CLEAPSSHazcard HC098a.
