Acetals with the general formula 29.1 have a configurationally nondefined center at C2. This leads to the paradox that the compound is identical after formal inversion at C2 and ensuing ring flip. However, O1 and O3 are diastereotopic and can be differentiated by forming a complex with aluminu...
On silica, the hydrogen-bonded interaction between surface hydroxyl groups and the adsorbate carbonyl groups has been confirmed. A new adsorbed species is found on heating acetaldehyde in the presence of silica at 120 °C, which can be convincingly identified as crotonaldehyde. It seems likely ...
The products of these reactions were investigated by the proton-transfer-reaction mass spectrum (PTR-MS). The results indicated that the major products observed in the atomic Cl reaction were formaldehyde together with chloroacetone for MBO332, and acetaldehyde and CH3C(O)C(O)Cl for MPO332. ...
The following inhibitors of spore germination were identified in collections of volatile metabolites from cultures of Fusarium oxysporum: acetaldehyde, propionaldehyde, n-butyraldehyde, n-propanol, iso-butanol, ethyl acetate, iso-butyl a...

To understand the kinetics of exchange of acetaldehyde between the air and the snow, its mechanism of incorporation in snow was investigated. Surface incorporation by adsorption, and volume incorporation by dissolution were considered. Winter and spring measurements showed very different trends, and ...
acetaldehyde (ethanal; ethylaldehyde; acetic aldehyde, CH3CHO). CAS number 75-07-0 An organic compound used in the manufacture of paraldehyde, acetic acid, butanol, aniline dyes, synthetic rubber, and in the silvering of mirrors. It is also used in trace quantities in artificial flavors. The...

Disulfiram, a drug used to treat alcohol dependence, may also increase BrAce through its acetaldehyde dehydrogenase inhibition. Temperature extremes also have effects on overall metabolic rate in humans and variations may correlate with BrAce changes [39]. These factors are important to consider when ...
