The invention provides a process for preparing azo colorants which comprises spraying one or more coupling components individually or in a mixture and one or more compatible diazonium salts individually or in a mixture, in their solution or suspension form through nozzles to a point of conjoint coll

The invention provides a process for preparing azo colorants which comprises spraying one or more coupling components individually or in a mixture and one or more compatible diazonium salts individually or in a mixture, in their solution or suspension form through nozzles to a point of conjoint collision in a reactor chamber enclosed by a housing in a microjet reactor, a gas or an evaporating liquid being passed into the reactor chamber through an opening in the housing for the purpose of maintaining a gas atmosphere in the reactor chamber, and the resulting product solution or suspension and the gas or the evaporated liquid being removed from the reactor through a further opening in the housing by means of overpressure on the gas entry side or underpressure on the product and gas exit side.
