摘要:
The present invention is directed at obtaining a high yield of a target substance and simultaneously securing high productivity.A reaction apparatus 10 has: a main flow channel 12 having an inner diameter of 3 mm, in which a raw material M1 flows; an introduction flow channel 14 in which a raw material M2 that causes a chemical reaction with the raw material M1 flows; and five branch introduction flow channels 16a to 16e which are branched from the introduction flow channel 14 and introduce the raw material M2 to the main flow channel 12, at predetermined introduction points 12o to 12s in the main flow channel 12. Here, in the main flow channel 12, the flow channel lengths of the flow channels 12b to 12d between adjacent introduction points 12p to 12s are not longer than those of the flow channels 12a to 12c between the next previous adjacent introduction points 12o to 12r in a flow direction of the raw material M1. At least one length of the flow channels 12b to 12d between the adjacent introduction points 12p to 12s is shorter than lengths of the flow channels 12a to 12c between previous adjacent introduction points 12o to 12r in the flow direction of the raw material M1.
摘要:
Disclosed is a manufacturing method for a fine powder exhibiting improved solubility, little impurity contamination, and a high recovery rate. Material to be ground and a grinding medium are suspended and stirred in a liquefied inert gas dispersion medium such as dried ice, and the material to be ground is made into a sub-micron or nano-sized fine powder. A uniform fine powder can be obtained when the material to be ground is a mixture having two or more components. Impurity contamination can be reduced by using granular dry ice as the grinding medium.
