Abstract: A new dehydroabietylamine derivative, i.e., N,N-dimethyl dehydroabietylamine oxide, was synthesized from dehydroabietylamine (99 %) via alkylation and oxidation. Its structure was identified by FT-IR and 1H NMR spectra. The oxidation conditions were optimized by the L16(45) orthogonal test. The results showed that suitable synthesis reaction conditions of the titled compound were as follows: N,N-dimethyl dehydroabietylamine oxide and H2O2 molar ratio of 1.5:1, reaction time of 12 h, EDTA of 1.5 % and reaction temperature of 80 ℃. The GC content of the tertiary amine oxide were above 70 % in repetitive experiments. The surfactivity experiment showed that the critical micelle concentration(CMC) can be as low as 0.2 g/L, and the surface tension is 22.75 mN/m. And a new type of adsorbent prepared from amine oxide-modified zeolite has better adsorption effect on a certain concentration of humic acid and Congo red. When the initial concentration of 40 mg/L reached equilibrium, the removal rates were 51.1% and 91.0 %, respectively.

Key words: dehydroabietylamine, tertiary amine oxide, surface activity, adsorption performance
