| description | The invention belongs to the technical field of sewage treatment, and particularly relates to a biquaternary ammonium bisulfonate degreasing agent as well as a synthesis method and application thereof. The synthesis method comprises the following steps: adding piperazine, sodium p-hydroxybenzenesulfonate, a formaldehyde solution and water into a four-neck flask, stirring, heating and carrying out reflux reaction to obtain a disulfonic acid bis-tertiary amine salt intermediate; carrying out reduced pressure distillation on the intermediate mixed solution until the intermediate mixed solution is dry to obtain a viscous solid, adding DMF (Dimethyl Formamide) and alkyl halide, carrying out heat preservation reaction, and evaporating to dryness by a rotary evaporator to obtain a disulfonic acid biquaternary ammonium salt crude product; adding ethyl acetate into the crude product, heating for dissolving, carrying out negative pressure suction filtration, cooling filtrate, separating out faint yellow solid, adding c |
