N,N-二甲基脱氢枞基氧化叔胺的制备及其性能
The Synthesis of N,N-Dimethyl Dehydroabietylamine Oxide and Its Properties
摘要
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 H2 O2 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.关键词
