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 ...
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.
For example, one can take advantage of the propensity of HOCl to undergo this addition reaction by adding a sacrificial alkene-containing chemical to the reaction mixture. This alternate substrate reacts with the HOCl, preventing the HOCl from undergoing reactions that interfere with the Pinnick reaction itself.
Cl 2 + H 2 → 2 HCl. As the reaction is exothermic, the installation is called an HCl oven or HCl burner. The resulting hydrogen chloride gas is absorbed in deionized water, resulting in chemically pure hydrochloric acid. This reaction can give a very pure product, e.g. for use in the food industry. The reaction can also be triggered by blue ...
The Pinner reaction refers to the acid catalysed reaction of a nitrile with an alcohol to form an imino ester salt (alkyl imidate salt); this is sometimes referred to as a Pinner salt. [1] The reaction is named after Adolf Pinner , who first described it in 1877.
The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety of techniques has been described. A variety of techniques has been described. The "fused" sample is plunged into water, and the qualitative tests are performed on the resultant solution for the respective possible constituents.
The reaction can be simplified by replacing the HCN/AlCl 3 combination with zinc cyanide. [4] Although it is also highly toxic, Zn(CN) 2 is a solid, making it safer to work with than gaseous HCN. [5] The Zn(CN) 2 reacts with the HCl to form the key HCN reactant and Zn(Cl) 2 that serves as the Lewis-acid catalyst in-situ.
For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq). The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water. [1] [2] As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent ...
