[0058] Example

[0059] like figure 1 As shown in the schematic diagram of all components of the supercritical particle preparation equipment system of the present invention,

[0060] A multifunctional supercritical particle preparation system is at least connected by pipelines, interfaces and valves, the pipelines and interfaces have standard fittings, including the following components:

[0061] (1) Cylinder C storing high-purity carbon dioxide, carbon dioxide cooler H, carbon dioxide pump B, valve one K1, the high-purity carbon dioxide in cylinder C is first cooled by carbon dioxide cooler H, and after reaching the temperature range required for supercritical conditions, it enters The carbon dioxide pump B is pressurized by the carbon dioxide pump, and the pressure value is displayed by the pressure gauge 3 P3, so that the carbon dioxide reaches the supercritical state, and then controlled by the valve 1 K1, and enters the subsequent reaction process;

[0062] (2) The ent...

Description

technical field [0001] The invention relates to a supercritical substance preparation technology, more specifically, to a multifunctional supercritical particle preparation system. Background technique [0002] The so-called supercritical state refers to a special state of matter. When a certain substance is above the critical temperature and critical pressure, the properties of the gas phase and liquid phase of the substance will tend to be similar, and finally a homogenous phase (Homogenous) will be achieved. The state at this time is called supercritical state, and this special fluid is called supercritical state. It is a supercritical fluid (Supercritical Fluid, SF). Supercritical fluids are compressible like gases and have fluidity like liquids, and their densities are generally between 0.1 and 1.0 g·ml -1 between. Due to its liquid-like dissolving ability, supercritical fluid can be defined as a heavy gas with controllable dissolving ability, or a state of matter in...
