Embodiment 1
[0046] 5wt.% linalool + 95wt.% limonene was used as the simulated essential oil. Tetrabutylammonium bromide was selected as the association extraction agent for association extraction, the mass ratio of tetrabutylammonium bromide to linalool was 20:1; the stirring temperature of association extraction was 50°C, the time was 1h, and static Set the temperature at 30° C. for 4 hours to obtain a limonene phase and a deep eutectic solvent phase containing linalool.
[0047] Detected by gas chromatography, the distribution coefficient of linalool is 14, the selectivity is 104, and the extraction rate is 96.5%.
[0048] A two-step stripping operation was performed on the deep eutectic solvent phase containing linalool. In the first step of stripping operation, n-hexane is selected as the stripping agent, and multi-stage cross-flow stripping is carried out to completely separate limonene from the deep eutectic solvent phase in the association extraction process, so as to achieve the ...
Embodiment 2
[0052] 4.5wt.% linalool + 95.5wt.% limonene was used as the simulated essential oil. Tetrabutylammonium chloride was selected as the association extraction agent for association extraction, and the mass ratio of tetrabutylammonium chloride to linalool was 30:1; the stirring temperature of association extraction was 55° C., and the time was 1 h. The temperature is 45° C., and the time is 4 hours to obtain a limonene phase and a deep eutectic solvent phase containing linalool.
[0053] Detected by gas chromatography, the distribution coefficient of linalool is 12, the selectivity is 84, and the extraction rate is 96.6%.
[0054] A two-step stripping operation was performed on the deep eutectic solvent phase containing linalool. In the first step of stripping operation, n-hexane is selected as the stripping agent, and multi-stage cross-flow stripping is carried out to completely separate limonene from the deep eutectic solvent phase in the association extraction process, so as t...
Embodiment 3
[0057] 5.5wt.% linalool + 94.5wt.% limonene was used as the simulated essential oil. Tetrabutylammonium chloride was selected as the association extraction agent for association extraction, and the mass ratio of tetrabutylammonium chloride to linalool was 20:1; the stirring temperature of association extraction was 45° C., and the time was 3 hours. The temperature is 45° C., and the time is 3 hours to obtain a limonene phase and a deep eutectic solvent phase containing linalool.
[0058] Detected by gas chromatography, the distribution coefficient of linalool is 13, the selectivity is 93, and the extraction rate is 95%.
[0059]A two-step stripping operation was performed on the deep eutectic solvent phase containing linalool. In the first step of stripping operation, n-heptane is selected as the stripping agent, and multi-stage cross-flow stripping is carried out to completely separate limonene from the deep eutectic solvent phase in the association extraction process, so as...
