Silvestre (2016) has evaluated the feasibility of engineering, vacuum fractional distillation to separate the components of green tangerines (Citrus Deliciosa Tenore) essential oils. The results obtained indicate that the feet are not fractional distillation is likely to split the terpenes, hydrocarbons are removed from the beginning of the period/columns, from terpenes with other chemical function, which remains at the bottom. Some micro-energy compounds, such as methyl-N-methyl anthranilate and alpha sinensal, its concentration increased more than tenfold after the split. The parts of the volume of the main compound of essential oil, D-limonene, fell from 0707 in crude oil, to 0218 at the bottom. There is no evidence of thermal degradation products of separation [10].
