Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols. Secondary alcohols form ketones, while primary alcohols form aldehydes or carboxylic acids. [1] A variety of oxidants can be used.
Ethyl sulfate can be produced in a laboratory setting by reacting ethanol with sulfuric acid under a gentle boil, while keeping the reaction below 140 °C. The sulfuric acid must be added dropwise or the reaction must be actively cooled because the reaction itself is highly exothermic. CH 3 CH 2 OH + H 2 SO 4 → CH 3 CH 2 OSO 3 H + H 2 O
The sulfur dioxide is oxidized to sulfur trioxide by oxygen in the presence of a vanadium(V) oxide catalyst. This reaction is reversible and the formation of the sulfur trioxide is exothermic. 2 SO 2 + O 2 ⇌ 2 SO 3. The sulfur trioxide is absorbed into 97–98% H 2 SO 4 to form oleum (H 2 S 2 O 7), also known as fuming sulfuric acid or ...
Sulfuric acid contains two hydroxy groups.. Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1).
In the third step, a negatively charged acetate ion deprotonates the alkyloxonium ion, forming the waste product HOAc. The two electrons participating in the bond between oxygen and the attacked hydrogen collapse into the oxygen, neutralizing its charge and creating the final alcohol product. Curved-arrow mechanism for the oxymercuration reaction.
1-Propanol (also propan-1-ol, propanol, n-propyl alcohol) is a primary alcohol with the formula CH 3 CH 2 CH 2 OH and sometimes represented as PrOH or n-PrOH.It is a colourless liquid and an isomer of 2-propanol. 1-Propanol is used as a solvent in the pharmaceutical industry, mainly for resins and cellulose esters, and, sometimes, as a disinfecting agent.
This reaction is important in the history of organic chemistry because it helped prove the structure of ethers. The general reaction mechanism is as follows: [3] An example is the reaction of sodium ethoxide with chloroethane to form diethyl ether and sodium chloride: C 2 H 5 Cl + C 2 H 5 ONa → C 2 H 5 OC 2 H 5 + NaCl
Under ideal conditions the reaction produces 50% of both the alcohol and the carboxylic acid (it takes two aldehydes to produce one acid and one alcohol). [5] This can be economically viable if the products can be separated and both have a value; the commercial conversion of furfural into furfuryl alcohol and 2-furoic acid is an example of this ...
