However, aldehydes are very reactive to a large number of reagents, so much so that their synthesis by reduction of carboxylic acids or their derivatives is difficult because the aldehydes are normally more readily reduced than the carboxylic acid or its derivative, and reduction through to the ...
An enzyme which we call carboxylic acid reductase (aldehyde dehydrogenase) seems to be the first which is able to reduce non-activated carboxylic acids to aldehydes at the expense of reduced viologens. There is no further reduction of the aldehydes to the corresponding alcohols. In the presence ...
The meaning of CARBOXYLIC ACID is an organic acid (such as acetic acid) containing one or more carboxyl groups.

acids with molecular hydrogen. Specifically, a process of reducing an organic carboxylic acid with molecular hydrogen in the presence of a catalyst into an aldehyde corresponding to the acid, characterized by conducting the reduction in the presence of a dehydrating agent such as a carboxylic ...

2-Hydroxy acids lose water upon heating to yield α,β-unsaturated acids. The simplest hydroxy acids, glycolic and lactic, occur in nature. Lactic acid is formed when milk turns sour (hence the name, from Latin lactis,“milk”) and was first isolated from sour milk by the Swedish chemist...
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 ...
