The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
When a sodium and carbonate ion-containing compound is used as the reactant, the carbonate anion from sodium bicarbonate or carbonate, reacts with the hydrogen from the carboxyl group (-COOH) in acetic acid, forming carbonic acid. Carbonic acid readily decomposes under normal conditions into gaseous carbon dioxide and water.
acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
It can be viewed as the result of homoassociation, an effect that enhances the acidity of acetic acid in concentrated solution: 2 CH 3 CO 2 H + NaOH → Na + [(CH 3 CO 2) 2 H] − + H 2 O. Also described as the sodium acid salt of acetic acid, it is best described as the sodium salt of the hydrogen-bonded anion (CH 3 CO 2) 2 H −.
An acetate is a salt formed by the combination of acetic acid with a base (e.g. alkaline, earthy, metallic, nonmetallic or radical base). "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula C
DMA is prepared commercially by the reaction of dimethylamine with acetic anhydride or acetic acid. Dehydration of the salt of dimethylamine and acetic acid also furnishes this compound: [5] CH 3 CO 2 H·HN(CH 3) 2 → H 2 O + CH 3 CON(CH 3) 2. Dimethylacetamide can also be produced by the reaction of dimethylamine with methyl acetate. [6]
Methyl acetate is produced industrially via the carbonylation of methanol as a byproduct of the production of acetic acid. [6] Methyl acetate also arises by esterification of acetic acid with methanol in the presence of strong acids such as sulfuric acid; this production process is famous [according to whom?] because of Eastman Kodak's intensified process using a reactive distillation.
Adams' catalyst is prepared from chloroplatinic acid H 2 PtCl 6 or ammonium chloroplatinate, (NH 4) 2 PtCl 6, by fusion with sodium nitrate. The first published preparation was reported by V. Voorhees and Roger Adams. [2] The procedure involves first preparing a platinum nitrate which is then heated to expel nitrogen oxides. [3]
