Benzaldehyde propylene glycol acetal Usage And Synthesis
Chemical Properties
Clear colorless to yellowish oily liquid
Chemical Properties
A colorless liquid with a very mild almond-like odor
Occurrence
Reported found in port wine.
Uses
Benzaldehyde Propylene Glycol Acetal, is a building block used in various chemical synthesis.
Definition
ChEBI: 4-Methyl-2-phenyl-1,3-dioxolane is a member of benzenes.
Preparation
By condensation of benzaldehyde with propylene glycol. The reaction water is removed by azeotropic distillation (Arctander, 1960).
General Description
The product is an isomeric mixture of benzaldehyde propylene glycol acetal (Benzaldehyde PG acetal). It can be prepared from benzaldehyde and propylene glycol, via condensation reaction. Specific gravity of benzaldehyde PG acetal is 1.068 – 1.073 at 20°C. It has been identified as one of the volatile compound present in the artificial caramel and chocolate samples by non-equilibrated solid-phase microextraction/gas chromatography/mass spectrometry.
