摘要： An insoluble azo pigment is produced by ejecting a diazo solution and a grounding solution continuously into an ejector such that within the ejector, the diazo solution and grounding solution are mixed with each other and are subjected to a coupling reaction. A production system for the insoluble azo pigment includes the following units (1) to (4): (1) a first feed tank (2) for a first fluid selected from the diazo solution or grounding solution, a first flow path (a) for feeding the first fluid to nozzles of an ejector (1), and a pump (d) for feeding the first fluid through the first flow path; (2) the ejector (1) provided with the nozzles, a suction chamber, a diffuser, and a temperature control device (g); (3) a second feed tank (3) for a second fluid, a second flow path (b) for guiding the second fluid into the suction chamber, and a flow control device (e) for controlling a flow rate of the second fluid through the second flowpath (b); and (4) a heat treatment tank (5) for subjecting to heat treatment a suspension of the insoluble azo pigment formed by a reaction between the first fluid and the second fluid, and a third flow path (a′) for guiding the suspension from the diffuser to the heat treatment tank.
