Colorless, slightly viscous liquid. Slightly soluble in water, soluble in alcohol
and most oils.
FEMA 3067 decomposes slowly in water,
particularly in the presence of mild acids.
The decomposition products are (mixed)
Tolylaldehydes and Glycerol.
Has apparently not been reported to occur in nature.
FEMA 3067 is preferred over Benzaldehyde for many purposes, mostly on account
of its more spicy and less pungent-chemical
aroma. It is used in imitation Chocolate,
Cherry, Coconut, Vanilla, Almond, Pistacio,
fruit complexes, etc. at concentrations from
less than 1 ppm up to 15 ppm in the finished
product.
From mixed tolyaldehydes and glycerol with phosphoric acid, finishing with an azeotropic distillation to remove water.
Acetals hydrolyse readily in the presence of acids to generate the corresponding aldehydes and alcohols (Fassett, 1963).
