Recently, Vaidya and Mahajani (2005) reported the hydrogenation study over Ru supported catalyst for n-valeraldehyde to n-amyl alcohol.
The heat adsorption observed are higher than those reported by Vaidya and Mahajani (2005) for n-valeraldehyde hydrogenation under same reaction mechanism (L-H model).
Mahajani, "Kinetics of Liquid-Phase Hydrogenation of n-valeraldehyde to n-amyl Alcohol Over a Ru/[Al.sub.2][O.sub.3] Catalyst," Chem.
Among these 22 malodorous compounds, 50% belong to VOC (toluene, styrene, m,p,o-xylenes, methyl isobutyl ketone, and ethyl acetate) and carbonyl compounds (acetaldehyde, propanal, n-butanal, n-valeraldehyde, i-valeraldehyde, and methyl ethyl ketone).
The compounds, such as butyraldehyde, i-valeraldehyde, and n-valeraldehyde, were detected with the lowest frequencies at all sites.
