1. for the production of the method for acetic acid, comprise the steps:

  • Thereby in comprising the reactor based on injector of reaction medium, make the productions of carbon monoxide and at least a reactant reaction comprise the reaction soln of acetic acid, wherein at least a reactant is selected from the group that is comprised of methyl alcohol, methyl acetate, methyl-formiate, dme and composition thereof, and wherein reaction medium comprises water, acetic acid, methyl acetate, methyl-iodide and catalyzer;

    Wherein the reactor based on injector comprises one or more injector mixing tanks;

    From the reactor based on injector, extract reaction soln with first flow;

    Thereby separate a part of reaction soln and form the pump recycle stream;

    Thereby the optional one or more vapour generators of a part of pump recycle stream process that make are produced outlet process flow and steam;

    Thereby the optional one or more interchanger of a part of pump recycle stream process that make are produced effluents;

    WithThereby at least one that the part of following one or more is fed to one or more injector mixing tanks provides the mixing of reaction medium in the reactor based on injector;

    pump recycle stream, outlet process flow or effluent.
