Title:
超臨界流体分散方法
Document Type and Number:
Japanese Patent JP7295554
Kind Code:
B2
Abstract:
To provide a supercritical fluid dispersion method having both excellent fluidity during processing and easiness of separation after processing, by using supercritical fluid for fluid to be mixed with an object to be processed.SOLUTION: A supercritical fluid dispersion method includes the first supercritical fluid dispersion step for obtaining the first dispersion by dispersing an object to be processed into supercritical fluid, and the second supercritical fluid dispersion step for obtaining the second dispersion by pressurizing and supplying the first dispersion to an orifice homogenizer part having a small-diameter passage part, and by miniaturizing the object to be processed in the first dispersion, and further includes, after the second supercritical fluid dispersion step, an isolation step for isolating a microminiaturization object of the object to be processed by removing the supercritical fluid from the second dispersion.SELECTED DRAWING: Figure 1
