To meet this goal steam distillation was implemented, as it lowered the organic molecule's high boiling point, from 176 to 90 , allowing the substance to be evaporated and condensed in a similar manner as water. Orange peels (OPs) were valorized in a lab-scale biorefinery loop for the recovery of limonene and the subsequent production of volatile fatty acids (VFAs) and activated carbon (AC). Equilibrium Death Scene, limonene that is extracted from the orange rinds is a monoterpene. Solid/liquid extraction of limonene was optimized using n -hexane at 85 C with an OPs-to-solvent ratio of 2:1, allowing for a limonene recovery yield of 1.20% w/w. You will note that, in addition to the unsaturation, limonene has a chiral carbon. The orange peel which is considered as a waste can be used for the extraction of limonene (D-Limonene) which has many applications ranging from food flavouring agent to cosmetics.
