The group is a constituent of carboxylic acids, esters, anhydrides, acyl halides, amides, and quinones, and it is the characteristic functional group (reactive group) of aldehydes and ketones. Carboxylic acids (and their derivatives), aldehydes, ketones, and quinones are also known collectively as...
Aldehydes are usually more reactive toward nucleophilic substitutions than ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side. In ketones, however...
Reactive extraction of carbonyl compounds (aldehydes, ketones) from hydrocarbon mixtures applying aqueous solutions of several amino and bisulfite salts was studied. Results obtained for hydrazone formation salts and sodium bisulfite show an increase of distribution ratio of benzaldehyde of up to 1000 ...

Oxidation of A2E Results in the Formation of Highly Reactive Aldehydes and Ketones 来自 Wiley 喜欢 0 阅读量: 27 作者:W Zhen,LMM Keller,J Dillon,ER Gaillard 摘要: It has been reported that the photo-oxidation of A2E, a component of human retinal lipofuscin, leads to products that are ...
NH4Cl-CR solution was able to distinguish monofunctional aldehydes from polyfunctional aldehydes and other compounds such as ketones, esters, amides, alcohols, anhydrides, and carboxylic acids. The characteristic color transition from red-orange to violet to blue provides a unique approach towards sensing...
Aldehydes and ketones are related to alcohols in the same manner that alkenes are related to an alkane. Know how to do the nomenclature of aldehydes and ketones. Nomenclature of Aldehydes and Ketones.
A reactive and sensitive diffusion sampler for the determination of aldehydes and ketones in ambient air We developed a diffusive sampling device (DSD-carbonyl) for organic carbonyl compounds (aldehydes and ketones) which is suitable for collection and analysi...

12.Protein modifications resulting from reactive aldehydes are thought to be involved in the pathogenesis of various degenerative diseases. 由活性醛基导致的蛋白质修饰被认为与多种退行性疾病的发病机制有关。 13.These reactions are therefore used to discern between ketones and aldehydes. ...
Apart from esters and ketones, aldehydes are an important chemical class to consider for the flavoring of plant-based products such as meat analogues. Therefore, probing the interactions between plant proteins and aldehydes is essential and could give great insights into the applicability of the ...
