To improve dispersibility by separately introducing solutions of reaction materials in a layers and parallel flow at the time of producing a finely divided dispersion such as a suspension from a liquid medium produced by the reaction of the reaction materials dissolved in a medium in a tubular reactor.
The solution of the product material A, such as a silver nitrate aq. solution from a feed conduit 2 and the reaction material B, such as an alkali metallic halide aq. solution from a fed conduit 3 are respectively introduced into a tubular reactor 1. At this time, the reaction material A is introduced into the tubular reactor from a nozzle plate 5 and on the other hand, the reaction material B is introduced from an annular space 4, and the medium containing no reaction material such as aq. gelatin solution is introduced between the nozzle plate 5 and the annular space 4 to separate the reaction material solutions from each other. The aq. gelatin solution is made to flow-in from the direction of the arrow to prevent the reaction material solution from being in contact with the reactor wall. The product suspension produced in the reactor 1 is discharged from an outlet end 8.
