Synthesis and characterization of glycidyl allyl dimethyl ammonium chloride (GADAC)

摘要

A brand new organic cationic monomer glycidyl allyl dimethyl ammonium chloride (GADAC) was synthesized with dimethylamine, allyl chlorine and epichlorohydrin to protect the oil and gas reservoirs from damage. The effect of temperature, pH, time and the mole ratio of reactants on cationic degree of GADAC was investigated by the orthogonal design experiments and then the effect of cation concentration on the cationic degree of GADAC was also studied. The optimal condition for synthesis was gained and the product was characterized by FIRS, and the results showed that the target-product had a very good performance of anti-expansion with a very high cationic degree of more than 97%.
