As shown in Figures 3b, 4b, and 5b, the main gaseous by-products were acetone, acetaldehyde, formaldehyde, and propionaldehyde
. Moreover, in some experiments trace amounts of benzaldehyde and crotonaldehyde were also found in the gas phase.
and butanone were found in similar proportions (ca.
and methyl tert-butyl ether (MTBE) had two of the strongest positive associations with ASD diagnosis.
Any material, compound, mixture, or preparation that is not listed as a controlled substance in another schedule, is not an FDA-approved drug, and contains any quantity of the following substances, their salts, isomers (whether optical, positional, or geometric), homologues, modifications of the indole ring by nitrogen heterocyclic analog substitution or nitrogen heterocyclic analog substitution of the phenyl, benzyl, naphthyl, adamantly, cyclopropyl, cumyl, or propionaldehyde
structure, and salts of isomers, homologues, and modifications, unless specifically excepted, whenever the existence of these salts, isomers, homologues, modifications, and salts of isomers, homologues, and modifications is possible within the specific chemical designation..., (208)
Formaldehyde, acetaldehyde, and propionaldehyde
were found at room temperature.
(19) Volatile aldehydes (formaldehyde, acetaldehyde, acrolein propionaldehyde
, and methacrolein) are toxicants known to cause pulmonary disease.
Pectin, depending on conditions, has been previously shown to generate aldehydes, such as formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde
, crotonaldehyde, methyl ethyl ketone, and butyraldehyde (Zhou et al.
Once commissioned, it will add a capacity of 100,000 mt/year of propanol and 40,000 mt/year of propionaldehyde
. Propanol is used to manufacture products mainly ending up in printing inks, coatings, adhesives and pharmaceuticals applications.
 obtained the LBV of three [C.sub.3][H.sub.6]O isomers, propylene oxide (cyclic ether), acetone (ketone), and propionaldehyde
(aldehyde) at room temperature and atmospheric pressure.
The world-scale plant, dubbed 'Propanol-2', will boost Oxea's propanol production capacity by around 100,000 metric tonnes/year, and its propionaldehyde
capacity by 40,000 mt/year, added the Oman Daily Observer report.
and 2-methyl-2-pentenal contents were different (p [less than or equal to] 0.05) in landraces samples: the highest values were in Aprilatica landrace, followed by Maggiaiola and Giugnese.
