Hydrogen peroxide (H 2 O 2) can be used as HOCl scavenger whose byproducts do not interfere in the Pinnick oxidation reaction: HOCl + H 2 O 2 → HCl + O 2 + H 2 O. In a weakly acidic condition, fairly concentrated (35%) H 2 O 2 solution undergoes a rapid oxidative reaction with no competitive reduction reaction of HClO 2 to form HOCl. HClO 2 ...
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.
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
The reaction produces sodium alkoxides, according to the following stoichiometry: RCOOR' + 6 Na + 4 CH 3 CH 2 OH → RCH 2 ONa + R'ONa + 4 CH 3 CH 2 ONa. In practice, considerable sodium is consumed by the formation of hydrogen. [citation needed] For this reason, an excess of sodium is often required. Because the hydrolysis of sodium is rapid ...
Alternatively, HCl can be generated by the reaction of sulfuric acid with sodium chloride: [17] NaCl + H 2 SO 4 → NaHSO 4 + HCl↑. This reaction occurs at room temperature. Provided there is NaCl remaining in the generator and it is heated above 200 °C, the reaction proceeds further: NaCl + NaHSO 4 → Na 2 SO 4 + HCl↑
One workaround to avoid this method is to reduce the carboxylic acid derivative all the way down to an alcohol, then oxidize the alcohol back to an aldehyde. Other alternatives include forming a thioester or a Weinreb amide, then reducing the new species to an aldehyde through the Fukuyama reduction or Weinreb reaction respectively, or using ...
Sodium chlorate can be used with hydrochloric acid (or also sulfuric acid and sodium chloride, the reaction of which generates HCl) to chlorinate aromatic compounds without the use of organic solvents. In this case its function is to oxidize the HCl to obtain either HOCl or Cl 2 (depending upon the pH) in-situ which are the active chlorinating ...
Sodium hypochlorite solutions, such as liquid bleach, will release toxic chlorine gas when mixed with an acid, such as hydrochloric acid or vinegar. A 2008 study indicated that sodium hypochlorite and organic chemicals (e.g., surfactants, fragrances) contained in several household cleaning products can react to generate chlorinated organic ...
