Carboxylic acids contain carboxyl groups that can undergo a wide range of chemical transformation. Therefore, they serve as key platform chemicals for the production of high value-added industrial products. Currently, the majority of carboxylic acid platform chemicals is produced predominantly through trad...

Bothaldehydesandketonescontain acarbonyl group, a functional group with a carbon-oxygen double bond. The names for aldehyde and ketone compounds are derived using similar nomenclature rules as for alkanes and alcohols, and include the class-identifying suffixes–aland–one, respectively: In an aldehyde...
1. Physical Properties of Carboxylic Acids Carboxylic acid molecules are polar due to the presence of two electronegative oxygen atoms. They also participate in hydrogen bonding due to the presence of the carbonyl group (C=O) and the hydroxyl group. ...

aWith the central atom E,acid strength increases as the number of oxygen attached to E increases. With the same number of oxygen s around E ,acid strength increases with the electronegativity of E.carboxylic acid are organic acids that contain an acidic hydroxyl group and a carbonyl 与中央原子...
The carboxylic acid modifiers control the alcohol adsorption affinity of the catalyst, resulting in tunable alcohol oxidation reactivity. MnO x modified with carboxylic acids exhibits chemoselectivity in hydroxynitrile synthesis via aerobic ammoxidation of hydroxyaldehyde. Results Catalyst synthesis and ...

Structures for Y which contain a single cyclic group, or a single naphthyl unit, directly bonded to the L group also often lead to compounds of Formula I which show a high Ps value in a tilted smectic host. Other examples of structures included in the present invention include those listed...
