Abstract

The invention discloses a fumaropimaric acid modified acrylamide compound, a preparation method thereof and a polymer prepared by the fumaropimaric acid modified acrylamide compound. A structural formula of the fumaropimaric acid modified acrylamide compound is shown in the description. As the fumaropimaric acid modified acrylamide compound is synthesized by taking fumaropimaric acid, a by-product of rosin which is a natural biomass resource, as a raw material, and then the fumaropimaric acid modified acrylamide polymer is obtained through polymerization of the fumaropimaric acid modified acrylamide compound, a synthesis step and a reaction device are simple, the operation is convenient, and the problems of poor heat resistance, difficulty in separation, slow reaction speed, low recycling use performance and the like and the technical problems of environment protection and safety are all solved due to excellent heat resistance, excellent adsorption performance to heavy metals and capability of being repeatedly used for multiple times of the obtained polymer.

Description

technical field [0001] The invention relates to a fumapimaric acid-modified acrylamide compound, a preparation method thereof and a prepared polymer. Background technique [0002] Acrylamide (AM) is a widely used organic chemical raw material, and hundreds of products can be produced by processing it as a monomer. The traditional synthetic methods of acrylamide include sulfuric acid hydration method and catalytic method, and the catalytic method includes metal catalysis and biocatalysis. The sulfuric acid hydration method is to hydrolyze acrylonitrile and water into acrylamide sulfate in the presence of sulfuric acid, and then neutralize to obtain acrylamide. This method is easy to obtain crystalline monomers, but the process is complicated, consumes a large amount of sulfuric acid and ammonia, and equipment corrosion And environmental pollution is serious, and production cost is high. Metal catalysis uses skeleton copper as a catalyst to catalyze the hydration of acrylami...
