Benzaldehyde propylene glycol acetal C??? ??, ??, ??
??? ??
Clear colorless to yellowish oily liquid??
Reported found in port wine.?? ??
By condensation of benzaldehyde with propylene glycol. The reaction water is removed by azeotropic distillation (Arctander, 1960).?? ??
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.Benzaldehyde propylene glycol acetal ?? ?? ? ???
