A continuous method for producing a Grignard adduct, wherein a flow consisting of an alkyl- or aryl halide and a water-free solvent and a further flow consisting of magnesium chips are fed to a reactor, and the magnesium chips are activated mechanically in the reactor by friction.
A device for producing a Grignard adduct comprising a reactor with at least one temperature-control device, at least two supply lines, and an outlet, a device for continuous conveyance of the magnesium chips, a device for mechanical activation of the magnesium chips, at least one magnesium storage container, and at least one pump for conveying the alkyl- or aryl halide.
