Synthesis of 3, 7-Dimethyl-2, 6-Octadienal Acetals from Citral Extracted from Lemon Grass, Cymbopogon citrates L

Abstract

Citral (3, 7-dimethyl-2, 6-octadienal)was hydro distilled from lemon grass and 3, 7-dimethyl-2, 6-octadienal acetals (Citral acetals) were synthesized from it. The latter was redistilled under vacuum and collected fractions at constant temperature. Para toluene sulphonic acid catalyst was used for the preparation of citral ethylene glycol acetal and citral propylene glycol acetal which are used in perfumery, favor, for fortifying lemon oil. GC, IR of synthesized product is recorded and graphs were determined. © 2014 Shahzadi P, et al.
