Commercially, 2-ethylhexanoic acid is produced by using the butyraldehyde method.
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).
