A process for the preparation of surfactants represented by Formulas (I), (II) or (III); or optionally mixtures thereof, reacting a phosphorus acid ester of the following Formula (IV)
wherein Rt is aryl, R2 is alkyl or aryl, with a hydrophilic polyoxyalkylene of the following Formulas (VIII), or (IX)
wherein R3 is alkyl with from about 1 to about 6 carbon atoms, and A is a hydrophilic polyoxyalkylene chain, and which reaction results in an intermediate compound Formulas (XI), (XII), or (XIII), wherein component (XI) results from the reaction of phosphorus ester (IV) with polyoxyalkylene (VIII); component (XII) results from the reaction of phosphorus ester (IV) with about two molecules of polyoxyalkylene (VIII), and component (XIII) results from the reaction of phosphorus ester component (IV) with polyoxyalkylene glycol (IX)
reacting the intermediate compound selected from the group consisting of Formulas (XI) through (XIII), with a hydroxylic compound R1-OH (X) to yield surfactant precursors comprised of Formulas (V), (VI), and (VII), respectively, wherein component (V) results from the reaction of component (XI) with R1-OH (X); component (VI) results from the reaction of component (XII) with R1-OH (X), and component (VII) results from the reaction of component (XIII) with R1-OH (X)
oxidizing said phosphorus ester-linked surfactant precursors selected from the group consisting of Formulas (V), (VI) and (VII), with an oxidizing agent to produce the surfactant composition of Formulas (I), (II) or (III), wherein the surfactant (I) results from the oxidation of component (V), surfactant (II) results from the oxidation of component (VI), and surfactant (III) results from the oxidation of component (VII).
一种制备以式(I)、(II)或(III)为代表的表面活性剂或其任选混合物的工艺,将下式(IV)的磷 酸酯与下式(VIII)或(IX)的亲水性聚氧亚烷基反应
其中 Rt 为芳基,R2 为烷基或芳基,与下式(VIII)或(IX)的亲水聚氧亚烷基反应
其中 R3 是含有约 1 至约 6 个碳原子的烷基,A 是亲水性聚氧亚烷基链,反应生成中间化合物 式(XI)、(XII)或(XIII),其中组分(XI)由磷酯(IV)与聚氧亚烷基(VIII)反应生成;组分(XII)由磷酯(IV)与约两分子聚氧亚烷基(VIII)反应而得,组分(XIII)由磷酯组分(IV)与聚氧亚烷基二醇(IX)反应而得
将选自由式(XI)至(XIII)组成的组的中间体化合物与羟基化合物 R1-OH (X) 反应,分别生成由式(V)、(VI)和(VII)组成的表面活性剂前体,其中组分(V)由组分(XI)与 R1-OH (X) 反应生成;组分(VI)由组分(XII)与 R1-OH (X) 反应生成,组分(VII)由组分(XIII)与 R1-OH (X) 反应生成
用氧化剂氧化选自由式(V)、(VI)和(VII)组成的组中的所述磷酯连接的表面活性剂前体,生成式(I)、(II)或(III)的表面活性剂组合物,其中表面活性剂(I)由组分(V)氧化生成,表面活性剂(II)由组分(VI)氧化生成,表面活性剂(III)由组分(VII)氧化生成。
