摘　　要：以三氯氧磷和Ｃ１０～Ｃ１８醇合成了五种长链烷基磷酸酯，产率≥９７５％。作为废纸脱墨剂主要成分，长链烷基磷酸酯具有明显捕集油墨粒子的作用。十二烷基磷酸单酯作为捕集剂用量占脱墨剂７０％时可使残余墨粒数降低８７％以上。适当的亲水亲油平衡值是选择捕集剂的主要依据。5 Kinds of long chain alkyl phosphate monoesters were synthesized and their serviceabilities as collector in deinking process were systematically researched.Lauryl phosphate brought about good deinking result.When its application rate in deinking agent was 70%,the residual ink particles can be reduced by 87%.
