THE POLYMERIZATION OF ACETALDEHYDE. II.

open access: yes, 1932
Using acetaldehyde prepared out of contact with oxygen, the specific gravities of this substance and its mixtures with paraldehyde have been determined, and shown to differ from those previously obtained.

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

ENZYMATIC CONVERSION OF INDOLE ACETALDEHYDE AND NAPHTHALENE ACETALDEHYDE TO AUXINS [PDF]

open access: yesPlant Physiology, 1951
A neutral substance, convertible to an acid auxin, is present in various plant extracts (5, 9) and chemical preparations (9). As indicated by a number of biological tests, the neutral substance is in all likelihood 3-indole acetaldehyde and will for convenience be designated by this name in the present paper.

High-sensitivitydetection of acetaldehyde

open access: yes, 2012
A set of sensors based on nanostructured single and mixed metal oxides has been prepared and employed in acetaldehydedetection within 0.1–10 ppm, this range being useful for many applications.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Photocatalytic Synthesis of Acetaldehyde by Selective Oxidation of Ethanol on RuOx-VOx/TiO2

open access: yesChemical Engineering Transactions, 2013
The gas-solid photocatalytic partial oxidation of ethanol to acetaldehyde on monometallic RuOx/TiO2 and bimetallic RuOx-VOx/TiO2 catalysts has been studied in a fluidized bed photoreactor at high illumination efficiency.

Acetaldehyde as the first hit of addictive behaviour

open access: yesJournal of Biological Research, 2016
Unhealthy alcohol use is common in the Western society, which puts risk of health consequences, causing multiple behavioural injuries. Increasing evidence focuses on acetaldehyde, the first metabolite of ethanol, as the mediator of the several ...
