Abstract
The invention discloses a preparation method of a quaternary ammonium cationic monomer aqueous solution. The preparation method comprises the following steps: after fully mixing a mixture of unsaturated tertiary amine and a polymerization inhibitor with water, continuously feeding the mixture to a tower reactor from the upper part of the tower reactor; and continuously introducing gas halohydrocarbon from the lower part of the tower reactor to the tower reactor, wherein the unsaturated tertiary amine and the gas halohydrocarbon in the tower reactor are in countercurrent contact to react, the reaction temperature is 35-60 DEG C and the reaction time is 3-15 minutes. The preparation method disclosed by the invention realizes continuous production and is short in reaction time, and the conversion ratio of the unsaturated tertiary amine reaches over 99.8%, the content of a byproduct acrylic acid is less than 1000ppm, the content of the byproduct is low, the product yield is high and the product quality is stable.
