Acetaldehyde Acetaldehyde Acetaldehyde
Acetaldehyde may be the injurious agent in acute alcoholic liver disease. It has been suggested that the mechanism of liver injury in this situation may be immunologically mediated. In the present study acetaldehyde has been bound to human liver plasma membranes. The activation of C3 by the acetaldehyde/membrane product was measured by immunofixation of the separated C3 components. Activation o...
متن کاملStudies on adsorption removal of odorous pollutants (acetaldehyde and methyl mercaptan), adsorption of acetaldehyde on porous adsorbents.
Acetaldehyde has recently been added to the list of chemicals in the control law for offensive odor in Japan, and its concentration in the atmosphere is limited by the law to the range of 0.05 to 0.5ppm1). Acetaldehyde is emitted into the atmosphere particularly from the factories producing acetic acid, vinyl acetate, and chloroprene. It is well known that acetaldehyde irritates the mucous memb...
متن کاملAdsorption and surface reactions of acetaldehyde on TiO2, CeO2 and Al2O3
The adsorption and surface reactions of acetaldehyde at 300–673 K on TiO2, CeO2 and Al2O3 were investigated by Fourier transform infrared spectroscopy and mass spectroscopy. Acetaldehyde adsorbs molecularly in two forms on the surfaces: (i) in a less stable H-bridge bonded form and (ii) in a more stable form adsorbed on Lewis sites through one of the oxygen lone pairs. Both forms of molecularly...
متن کاملEnzymatic Conversion of Indole Acetaldehyde and Naphthalene Acetaldehyde to Auxins.
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. In a previous paper (11) it was shown that 3-indole acetaldehyde is rapidly converted ...
متن کاملPurity Determination of Acetaldehyde in an Acetaldehyde Certified Reference Material.
Acetaldehyde is regulated as a toxic substance in various fields, and the method for monitoring or analysis of acetaldehyde is important. However, handling is difficult because of the high reactivity and low boiling point of acetaldehyde. Therefore, a reference material for high purity acetaldehyde with high accuracy was not available. Although the measuring method of acetaldehyde as a reagent ...
