Technical Document

Brief Overview
Benzaldehyde is used in aroma compositions due its bitter almond odor and is applied as a starting material for a large number of aliphatic fragrance and flavor materials.
b) Manufacturing Process
A significant quantity of natural benzaldehyde is produced from cinnamaldehyde obtained from cassia oil by the retro-aldol reaction. There are two main steps:
The cinnamaldehyde is heated in an aqueous/alcoholic solution between 90 °C and 150 °C with a base (most commonly sodium carbonate or bicarbonate) for 5 to 80 hours.
Then, it is followed by distillation of the formed benzaldehyde. This reaction also yields acetaldehyde. The natural status of benzaldehyde obtained in this way is controversial.
