new elaborated technique for isolation and purification of limonene from orange oil
Authors
abstract
essential oil of the orange peel which was extracted by hydrodistillation method showed 50 different mono- and sesquiterpenes on gc-ms analysis, in which limonene had the highest percentage (92.4%). due to various important uses of the compound, a method was developed for isolation and purification of limonene. in this method, for extra purification, a fractional distillation on vigreux column under 100 mm hg vacuum was used which resulted in 96.7% purity for limonene. subsequent chromatography by two different packages of silica gel and active charcoal columns resulted in 99.4% and 99.9 % purity of limonene, respectively.

Biobased monomers derived from castor oil as well as from limonene suitable for thiol–ene copolymerization were synthesized. Di‐10‐undecenylether 2 was obtained via GaBr3‐catalyzed reduction of 10‐undecenyl 10‐undecenoate 1. Diene ether 2 and (R)‐limonene 5 were reacted in two steps using radical thiol–ene addition reactions to dithiol ether 4 and dithiol 7, respectively. Diene ether 2 and dith...

Bergamot peel oil is highly attractive for food and pharmaceutical industries due to its content of valuable essential oil, which is enriched with high-added valuable compounds, such as limonene, linalool and linalyl acetate. Nevertheless, there are some limitations for the separation of such compounds. In this framework, pervaporation (PV) technology was proposed as a ...
