Example Embodiment
[0029] Example 1
[0030] The cyclohexanol-containing aqueous solution with a concentration of 10,000 ppm was passed through a grid to remove impurities. The eucalyptol and cyclohexanol aqueous solution were placed in the extraction vessel in a volume ratio of 0.5:1. Under the condition of 10°C, the rotating speed of the magnetic stirrer is 500 rpm, stirring for 10min, and standing for 1h in a constant temperature bath with a temperature of 10°C. After standing, the solution was divided into upper and lower phases, the lower raffinate phase was separated, and the cyclohexanol content in the raffinate phase was measured by gas chromatography to be 70 ppm.
Example Embodiment
[0031] Example 2
[0032] The cyclohexanol-containing aqueous solution with a concentration of 20,000 ppm was passed through a grid to remove impurities. The eucalyptol and cyclohexanol aqueous solution were placed in the extraction vessel at a volume ratio of 1:1. Under the condition of 25°C, the rotating speed of the magnetic stirrer is 500 rpm, stirring for 10min, and standing for 1h in a constant temperature bath with a temperature of 25°C. After standing, the solution was divided into upper and lower phases, the lower raffinate phase was separated, and the cyclohexanol content in the raffinate phase was measured by gas chromatography to be 110 ppm.
Example Embodiment
[0033] Example 3
[0034] The cyclohexanol-containing aqueous solution with a concentration of 30,000 ppm was passed through a grid to remove impurities. The eucalyptol and cyclohexanol aqueous solution were placed in the extraction vessel at a volume ratio of 1:1. Under the condition of 25°C, the rotating speed of the magnetic stirrer is 500 rpm, stirring for 10min, and standing for 1h in a constant temperature bath with a temperature of 25°C. After standing, the solution was divided into upper and lower phases, the lower raffinate phase was separated, and the cyclohexanol content in the raffinate phase was measured by gas chromatography to be 120 ppm.
