Abstract

The invention provides a 5L apparatus for extracting nanocrystalline by supercritical carbon dioxide, which comprises a carbon dioxide steel cylinder, a flowmeter connected to the carbon dioxide steel cylinder, a condenser connected to the flowmeter, a high pressure pump and an entrainer pump connected to the condenser, a heater connected to the high pressure pump, a 5L extraction kettle connected to the heater, and an extract crystallizer connected to the 5L extraction kettle, and the extract crystallizer is connected to the carbon dioxide steel cylinder through the flowmeter. The apparatus of the invention can be used for extracting nanocrystalline.

Description

technical field [0001] The invention relates to a 5L supercritical carbon dioxide extraction nanocrystal device, which belongs to the technical field of extraction. Background technique [0002] The supercritical fluid extraction separation process is carried out by using the relationship between the dissolving ability of supercritical fluid and its density, that is, utilizing the influence of pressure and temperature on the dissolving ability of supercritical fluid. When the gas is in a supercritical state, it becomes a single phase state between liquid and gas, with a density close to that of liquid, although its viscosity is higher than that of gas but significantly lower than that of liquid, and its diffusion coefficient is 10 to 100 times that of liquid; Therefore, it has good permeability and strong dissolving ability to the material, and can extract some components in the material. [0003] Due to the low critical temperature and critical pressure of CO2 gas (31.06o...
