Technology for the production α-hexyl cinnamaldehyde via green catalytic route
IPR Status & Details:
IN 201611009896
Application/Uses/Problem being addressed
α-Hexyl cinnamaldehyde is found naturally in the essential oil of chamomile. It is an aroma substance and a common additive in perfume and cosmetic industry. Traditionally it is manufactured from the reaction of benzaldehyde and n-octanal in presence of alkali metal hydroxide as a catalyst.
Limitations of the existing process:
Advantages of the catalytic process:
Salient Technical Features including Competing Features/ Impact
The process for preparation of -hexyl cinnamaldehyde involves catalytic cross aldol condensation between benzaldehyde and 1-octanal using a soft solid base catalyst, hydrotalcite
TRL Level & Scale of Development:- TRL 4 TRL Reference
Scaled at 200 g with 99% conversion and >95% selectivity
Business scope & opportunity (in terms of scale, cost, market etc.)
Being a perfumery chemical, -hexyl cinnamaldehyde has potential market scope; One of the important perfumery chemicals used in Indian industry which is currently to a large extent imported from China
Environmental Considerations
The process for -hexyl cinnamaldehyde works in solvent-free condition making the process environmentally benign; Uses heterogeneous solid catalyst; no aqueous effluent generation
