The best results for high-quality distillates were obtained at 85 °C (EVT) and confirmed that linalyl acetate content increased from 51.54 mg/g (initial Bulgarian lavender extract, L-Bg-E) and 89.53 mg/g (initial Polish lavender extract, L-Pl-E) to 118.41 and 185.42 mg/g, respectively, corresponding to increases of 2.3 and 2.1 times in both.
Using Steam Distillation to Produce Essential Oils
The separation of acidic and basic components from a crude mixture is often one of the first steps in separating the components of a crude natural product extract. It can save a lot of purification time if one knows beforehand that the desired compound of interest is acidic or basic. 2. Separation By Boiling Point Differences (Distillation)

Steam distillation is the most widely used method for plant essential oil extraction. The total yields of the volatile fractions obtained through HD and SFME were 0.31% and 0.39%, respectively. HD oil contained more monoterpene hydrocarbons (32.95%) than SFME-extracted oil (25.77%), while higher amounts of oxygenated monoterpenes (28.6%.

Extractive distillation is one of the efficient techniques for separating azeotropic and low-relative-volatility mixtures in various chemical industries. This paper first provides an overview of thermodynamic insight covering residue curve map analysis, the application of univolatility and unidistribution curves, and thermodynamic feasibility study. The pinch-point analysis method combining.

The extract obtained at 55 °C in 30 min had a strong Ginger flavour and nuances. Argo et al.,. The EO was extracted using the same 2-L steam distillation equipment. The distillation time (DT) examined in this experiment were 1.5, 3, 3.75, 15, 30, 60, 90, 120, 150, 180, and 240 min. At 60 min DT, the actual oil output (which ranged from 0.5.

An extractive distillation module. Extractive distillation is a powerful technique utilized to separate close-boiling and azeotropic mixtures. As it gains wider consideration within industrial chemical processes, it is important to understand the inner workings and possible applications. Discussed here is an introduction to this technology and.
DISTILLATION APPARATUS
Solvent extraction is the most widely used method. The extraction of natural products progresses through the following stages: (1) the solvent penetrates into the solid matrix; (2) the solute dissolves in the solvents; (3) the solute is diffused out of the solid matrix; (4) the extracted solutes are collected.

Aromatic/aliphatic separation stands as a challenge for both industry and academia. More and more efforts are being made to improve energy-demanding technologies based on liquid-liquid extraction or extractive distillation processes. Recently, ionic liquid-based technologies devoted to separating benzene, toluene, and xylene from pyrolysis gasoline have been evaluated, and extractive.
Distillation, Steam distillation, Essential oils
Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures having a low value of relative volatility, nearing unity. Such mixtures cannot be separated by simple.
Steam distillation (G.C.E. O/L Science) YouTube
The composition of azeotropic mixtures has the probability to deviate significantly from their azeotropic point. This study proposes a single-column side-stream extractive distillation (ED) combined with a front-side reboiler process to address the separation challenges posed by such azeotropic mixtures. The proposed process integrates the functions of preconcentration, ED, and entrainer.

The extracts obtained using SHDE were tested for their antibacterial activity. Only the SHDE extract was found to have antibacterial effects; there were no inhibition zones for samples of the distillation residue and hydrolate. The SHDE extract had the greatest antibacterial effect against the strain Streptococcus canis. In conclusion, we can.
