A weakly basic amine diazonium salt preparation method, and its preparation tertiary amine weakly basic amine azo dye method

The invention relates to a preparation method for weak-base arylamine diazonium salt and a method for preparing tertiary amine weak-base arylamine azo dye by the weak-base arylamine diazonium salt, and belongs to the technical field of clean production of the dye. The preparation method comprises the following steps of adding naphthalenesulfonic acid and alkyl nitrite to weak-base arylamine solution in sequence, reacting for 20min to 60min at 0 DEG C to 25 DEG C, and performing solid-liquid separation to obtain weak-base arylamine diazonium salt solid; solvent for dissolving weak-base arylamine is tetrahydrofuran, 1,4-dioxane, glycol dimethyl ether, ethylene glycol diethyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether or ethyl acetate. The preparation method for the weak-base arylamine diazonium salt and the method for preparing the tertiary amine weak-base arylamine azo dye by the weak-base arylamine diazonium salt, disclosed by the invention, have the beneficial effects that no sulfuric acid is used in a process of preparing the weak-base arylamine diazonium salt and the tertiary amine weak-base arylamine azo dye, therefore the environment is protected.

Clean preparation method for weakly alkaline arylamine azo disperse dye

The present invention provides a clean preparation method for weakly alkaline arylamine azo disperse dye. The method is characterized in that when a weakly alkaline arylamine diazonium double salt solid is coupled with a coupling component, the coupling component is pretreated to obtain a fine particle dispersion to be coupled with the weakly alkaline arylamine diazonium double salt; and the generated disperse dye is precipitated from the coupling system and is filtered and dried, thereby obtaining the weakly alkaline arylamine azo disperse dye. According to the preparation method provided by the present invention, by using a stable double salt structure of a diazonium salt, during the coupling, the process of adding acid for dissolution can be omitted; the coupling is performed at the normal temperature, and extra cooling is not required; and the method has a broad application prospect.
