Abstract
Provided is a method for producing particles, the method including a particle generating step of forming a product particle flow including target product particles by heating a segmented reaction raw material liquid flow divided into segments by a gas for segmentation under applying pressure at a pressure P(MPa) and at a heating temperature T (° C.) to react the raw material for particle formation to generate the target product particles, in which, at the particle generating step, (V/V) is 0.200 to 7.00 and the pressure Pat the particle generating step is 2.0 times or more a vapor pressure P(MPa) of a solvent at the heating temperature T. According to the present invention, a method for producing particles having a narrow particle size distribution with high production efficiency can be provided.
