FEMA 3067 Usage And Synthesis

Physical properties

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.

Occurrence

Has apparently not been reported to occur in nature.

Uses

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.

Preparation

From mixed tolyaldehydes and glycerol with phosphoric acid, finishing with an azeotropic distillation to remove water.

Metabolism

Acetals hydrolyse readily in the presence of acids to generate the corresponding aldehydes and alcohols (Fassett, 1963).
