Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap.
The Zeisel determination or Zeisel test is a chemical test for the presence of esters or ethers in a chemical substance. [1] [2] [3] [4]It is named after the Czech chemist Simon Zeisel (1854–1933).
Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.
Esters of propanoic acid are produced commercially by this method: H 2 C=CH 2 + ROH + CO → CH 3 CH 2 CO 2 R. A preparation of methyl propionate is one illustrative example. H 2 C=CH 2 + CO + CH 3 OH → CH 3 CH 2 CO 2 CH 3. The carbonylation of methanol yields methyl formate, which is the main commercial source of formic acid. The reaction is ...
Ester hydrolysis is an organic reaction which hydrolyzes an ester to a carboxylic acid or carboxylate, and an alcohol. It can be performed with acid as catalyst, or ...
Acetyl chloride is a reagent for the preparation of esters and amides of acetic acid, used in the derivatization of alcohols and amines. One class of acetylation reactions are esterification, for example the reaction with ethanol to produce ethyl acetate and hydrogen chloride: CH 3 COCl + HO−CH 2 −CH 3 → CH 3 −COO−CH 2 −CH 3 + HCl
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Xanthate salts of alkali metals are produced by the treatment of an alcohol, alkali, and carbon disulfide.The process is called xanthation. [2] In chemical terminology, the alkali reacts with the alcohol to produce an alkoxide, which is the nucleophile that adds to the electrophilic carbon atom in CS 2. [3]
