Greener Synthesis of Jasminaldehyde via Cross Aldol Condensation Reaction Using Recyclable Phase Transfer Catalysis and its Cosmetic Application

Jasminaldehyde or alpha amyl cinnamic aldehyde is a commonly used aroma molecule in perfume formulationsThe aldol condensation of equimolar n-heptanal and benzaldehyde in NaOH using a surfactant catalyst cetyltrimethylammonium bromide to achieve high cross aldol product Jasminaldehyde selectivity was studied. The process is highly efficient due to the recyclability of the catalyst. The process was studied for four cycles of catalyst reusability. The selectivity of the cross product was dependent on the temperature, surfactant concentration, and mixing. The olfactive profile of Jasminaldehyde obtained with 0.1 M surfactant solution was identical to the standard. Jasminaldehyde formulation was created and applied to in-home care applications.
