Abstract
The invention relates to 1, 1, 2, 2-tetrahydroperfluoroalkyl substituted allyl quaternary ammonium salt as well as a preparation method and application thereof, and belongs to the technical field of natural gas purification high-salt industrial wastewater flocculation treatment. In order to solve the problems that in the prior art, synthesis of a cationic polymer flocculant needs to use a large number of surfactants and operation is complex, 1, 1, 2, 2-tetrahydroperfluoroalkyl iodide and N-methylallylamine are adopted for a substitution reaction; performing quaternization reaction on methyl iodide and the substitution reaction product to obtain 1, 1, 2, 2-tetrahydroperfluoroalkyl substituted allyl quaternary ammonium salt; and polymerizing the 1, 1, 2, 2-tetrahydroperfluoroalkyl substituted allyl quaternary ammonium salt and acrylamide to obtain the novel cationic polyacrylamide flocculant. The cationic fluorocarbon modified hydrophobic association polyacrylamide flocculant is synthesized by adopting an aqueous solution polymerization method, the operation is simple, a surfactant is not needed, and experiments show that the prepared flocculant has an excellent flocculation effect.
