| Abstract: | Poly（ethylene glyeol） tosylate（PEG-OTs） was prepared by using triethylamine as acid binding agent.Effect of molar ratio of polyethylene glycol/p-toluenesulfonyl chloride,triethylamine dosage,reaction temperature and reaction time on preparation of poly（ethyleneglyeol）tosylate were investigated by orthogonal test.The optimal reaction conditions were obtained as follows： mole ratio of poly（ethylene glyeol）/p-toluenesulfonyl chloride 1：2.8,triethylamine 30 mL,reaction temperature 45 ℃ and reaction time 9 h.The yield of PEG-OTs can reach 89.7% under the optimal reaction conditions. |
