Carboxylic acids and/or esters are obtained by reacting a monohydric alcohol with CO in the presence of liquid HF. Preferably the liquid HF contains 1 to 15% by wt. of water. Substantially pure CO or mixtures thereof with inert gases may be used. The process may be carried out batchwise...
Carboxylic acids and esters are one of the most important classes of organic compounds. They are everywhere: * in food (citric acid; vinegar = a solution of ace…

Since the molecules in the unsaturated fatty acids are not as close to each other, less energy is needed to separate them, and a lower melting-point results. This situation is paralleled in the fats themselves, which are esters of these long-chain carboxylic acids where the alcohol component ...
The carboxylic acids and their derivatives are abundant in nature and were among the first organic substances to be isolated. ? Because they have been known for so long, the common acids, esters, and other acyl compounds are often referred to by their common names. 11.2 Nomenclature of ...

Carboxylic acid - Properties, Structure, Reactions: The most important property of carboxylic acids, and the one that is responsible for naming them such, is their acidity. An acid is any compound that donates a hydrogen ion, H+ (also called a proton), t

” The acids containing an odd number of carbon atoms greater than nine generally do not have common names. The reason is that long-chain carboxylic acids were originally isolated from fats (which are carboxylic esters), and generally these fats contain carboxylic acids with only an even number...
