Commercially, 2-ethylhexanoic acid is produced by using the butyraldehyde
Hexanal and butyraldehyde
were two predominant aldehydes, contributing 23.4% and 19.6% of total identified volatiles, respectively, for Hanwoo beef and 27.5% and 22.8% of total identified volatiles, respectively, for Chikso beef.
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.
While it is insoluble in practically all organic solvents it can be made to react with polymers such as butyraldehyde
to form a tough, clear, adhesive, and water-resistant plastic film.
Acrolein, propionaldehyde, crotonaldehyde, and butyraldehyde
(99.5%) were purchased from Quality Control Chemicals INC (USA); acetone and butanone (>99%) were purchased from Fisher (UK); deionized/distilled water was made by Thermo Scientific GenPure.
It is obtained by the condensation of butyraldehyde
with polyvinyl alcohol (PVA), which is a derivative of poly vinyl acetate (PVAc), in the presence of an acid catalyst [3-5].
On the basis of that identification we found formaldehyde, acetic acid, pyridine-2-aldehyde, ozone, acetone, propionaldehyde, methacrolein, butyraldehyde
and benzaldehyde (samples MA-R-5 to MA-R-10).
was a critical by-product from ozonation of 1-butanol.
Konstanz, Germany, December 17, 2014 --(PR.com)-- Direct applications of propylene include, besides the plastic polypropylene, production of important chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde
, and acrylic acid.
The study by market research institute Ceresana pointed out that its direct applications include production of important chemicals such as propylene oxide, acrylonitrile, cumene, butyraldehyde
and acrylic acid, besides the plastic polypropylene.
However, it disperses into water and butyraldehyde
at a temperature higher than 160[degrees]C (Kabanov et al.
