Carboxylic Acid - A Carboxylic Acid is an Organic Compound Containing a Carboxyl Functional Group. When a carbonyl carbon also bears a hydroxyl group, then these compounds are appreciably acidic and are called carboxylic acids. Visit BYJU’S to learn mor
The carbon where the other functional groups are attached is assigned numbers, with the carbonyl carbon of the carboxylic acid group assigned as the carbon 1. In writing their names, the substituents are arranged in alphabetical order, regardless of their carbon number. Below are some of the ...
Annual US production of maleic anhydride, mainly by vapor-phase oxidation of n-butane, is ~260,000 metric tons, not including maleic anhydride produced as an intermediate in the synthesis of 1,4-butanediol. Acetic, propionic, and butyric acids are short-chain fatty acids. Acetic acid is a ...
A chemical reaction, diffusion, and ionization model is presented for the dissolution of solid, weak acids in reactive media. The model assumes an equilibrium plane, which is located within the diffusion layer and in which ionization equilibrium is established. The model, which proposes that the ...
The resulting membrane behaved as a charge-mosaic membrane at higher pH values and as an anion-exchange membrane at lower pH values, the behavior corresponding to the degree of dissociation of the carboxyl group. This weak acid-strong base type charge-mosaic membrane exhibited quite high ion ...
A new type of hyperbranched aromatic poly(ether ketone) terminated with carboxylic acid groups (P2) was synthesized via a one-step polycondensation of a symmetric AB2 monomer, 4,40-(m-phenylenedioxy)-bis(benzenecarboxylic acid), using phosphorous pentoxide-methanesulfonic acid (PPMA) as a ...
In acidic solution, the weak nucleophile water attacks carbonyl carbon atom, having protonated oxygen atom; then carboxylic acid derivatives and alcohol groups are formed [28]. Determination of acid dissociation constants ([pK.sub.a]) of bicyclic thiohydantoin-pyrrolidine compounds in 20% ethanol-wat...
Carboxylic Acids and Esters
The molecular adducts of indole-3-acetic acid (iaa) and indole-2-carboxylic acid (ica) with 5-nitroquinoline (nq), [(iaa)(nq)2] (1) and [(ica)(nq)] (2), have been prepared and characterized by X-ray diffraction and spectroscopic methods. Both examples involve charge transfer as wel...
Cyclopropanes are very weak acids. Their metallation being slow and leading to poor yields of products, they constitute a bench mark to probe the effectiveness of a superbasic reagent. Cyclopropane, when used as a cosolvent, afforded not more than 20% of cyclopropanecarboxylic acid (101) when ...
