Abstract: In this paper,the dehydroabietylamine molecularly imprinted polymer(MIP) has been synthesized with dehydroabietylamine as a template,acrylic acid as a functional monomer and ethylene glycol maleic rosinate acrylate as a crosslinker.The structure and performance of the polymer have been investigated.Its application for the separation and purification of dehydroabietylamine has also been studied.The result showed that the optimum polymerization conditions were: the mixing molar ratio of dehydroabietylamine,acrylic acid and ethylene glycol maleic rosinate acrylate is 1:4:8;chloroform(30 mL),gasoline(15 mL) and distilled water(300 mL) were mixed as solvents.The amount of initiator used is 5% of the total amount of reactants.The polymerization reaction was taken at 70~80 ? for 5 h with the stirring speed of 300 r/min.MIP's static adsorbance for droabietylamine was determined as 223 mg/g.The desorption ratio was 95.9%.The optimum static adsorption conditions were:2 g/L dehydroabietylamine(mass concentration) in 80% alcohol solution(volume fraction) was adsorbed by 20~40 mesh MIP at 70 °C with stirring at 150 r/min.The purity of dehydroabietylamine was raised from 67.4% to 98.3%(mass fraction).
