【摘要】 以辛醇、环氧乙烷、环氧丙烷、乙二醇二缩水甘油醚、三氯氧磷为原料,在KOH、BF3-乙醚溶液的催化作用下合成了不同聚合度的孪链磷酸酯聚醚。研究了聚醚聚合度对办公废纸脱墨性能的影响,结果表明,该类聚醚在聚合度较低时(n<7)具有良好的脱墨效果。更多还原

【Abstract】 Gemini phosphate polyethers with different degree of polymerization were synthesized applied n-octanol,ethylene oxide,propylene oxide,glycol diglycidyl ether and phosphorus oxychloride as raw materials and potassium hydroxide,BF3-ethyl ether as catalyst.The influence of such surfactants on the performance of office waste deinking were studied.The results showed that the surfactants with low degree of polymerization(n<7)had good efficiency.更多还原
