Benzenesulfonic acid, dodecyl(sulfophenoxy)-, disodium salt - Synthesis of sodium dodecyldiphenyl ether disulfonate
from VIP Journal Professional Edition
Author:
Su Yu , MDE , Xue Zhonghua
Abstract:
The synthesis process of Sodium dodecyl diphenyl ether disulfonate as Anionic Surfactant was studied. The optimum reaction conditions were obtained as follows: the amount of catalyst was n (reactant): n (catalyst) = 5: 1; the reaction time was 5 h, the reaction temperature was 70 ℃, and the conversion of diphenyl ether was 82%. The optimum reaction conditions for sulfonation of fuming sulfuric acid are as follows: w(SO3)= 15%; Reaction temperature 35 ℃; Reaction Time 1 h;n (reactant): n (fuming sulfuric acid) = 1: 2.5; The number of sulfonic acid groups was 1.90. The optimum reaction conditions for sulfonation of chlorosulfonic acid are as follows: reaction time 20 min;n (reactant): n (chlorosulfonic acid) = 1: 5; Reaction temperature 15 ℃; The number of sulfonic acid groups is 1.92.

Abstract:
The present invention relates to the technical field of anionic surfactants, in particular to a highly effective bifunctional anionic surfactant sodium dodecyldiphenyl ether disulfonate using tripolybutene as a raw material. The sodium dodecyldiphenyl ether disulfonate is prepared by using tripolybutene as a raw material for alkylation. A more highly branched tripolybutene was used as the alkylation feedstock and as the lipophilic group in the product. The product has better lipophilicity and emulsion retention ability.
sovereignty:
1. A highly effective bifunctional anionic surfactant sodium dodecyldiphenyl ether disulfonate using tripolybutene as a raw material, characterized in that the sodium dodecyldiphenyl ether disulfonate is prepared by using tripolybutene as an alkylation raw material.

Benzenesulfonic acid, dodecyl(sulfophenoxy)-, disodium salt - Effect of sodium dodecyldiphenyl ether disulfonate pretreatment on bleaching of deinked pulp
from VIP Journal Professional Edition
Author:
Abstract:
The effect of sodium dodecyldiphenyl ether disulfonate (MADS) on the pretreatment of deinked pulp before H2O2 bleaching was studied and compared with the pretreatment effects of diethylenetriamine acetate, ethylenediaminetetraacetate and H2SO4. The results show that MADS is an excellent pretreatment agent. For newsprint deinked pulp, the suitable conditions of MADS pretreatment are as follows: the mass of MADS is 0.6% of newsprint deinked pulp, pH = 10, temperature 45 ℃, time 30 min, the whiteness increase after bleaching can reach 4.6% ISO.
