For example, acetic acid is a weak acid which has a = 1.75 x 10 −5. Its conjugate base is the acetate ion with K b = 10 −14 / K a = 5.7 x 10 −10 (from the relationship K a × K b = 10 −14 ), which certainly does not correspond to a strong base.
the ionization of substituted phenols in water (+2.008) the acid catalyzed esterification of substituted benzoic esters in ethanol (-0.085) the acid catalyzed bromination of substituted acetophenones (Ketone halogenation) in an acetic acid/water/hydrochloric acid (+0.417) the hydrolysis of substituted benzyl chlorides in acetone-water at 69.8 ...
Fumaric acid is (E)-1,4-but-2-enedioic acid, a trans isomer, whereas maleic acid is the corresponding cis isomer, i.e. (Z)-1,4-but-2-enedioic acid (see cis-trans isomerism). Fumaric acid has pK a values of approximately 3.0 and 4.5. By contrast, maleic acid has pK a values of approximately 1.5 and 6.5.
The conversion between hydroxyl value and other hydroxyl content measurements is obtained by multiplying the hydroxyl value by the factor 17/560. [2] The chemical substance may be a fat, oil, natural or synthetic ester, or other polyol. [3] ASTM D 1957 [4] and ASTM E222-10 [5] describe several versions of this method of determining hydroxyl value.
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 ...
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.
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.
Acrolein and malonic acid react in pyridine to give trans-2,4-pentadienoic acid with the loss of carbon dioxide. The Doebner modification of the Knoevenagel condensation entails the use of pyridine as a solvent with at least one of the withdrawing groups on the nucleophile is a carboxylic acid , for example, with malonic acid .
