摘要：以三苯乙烯基苯酚聚氧乙烯醚 TSPOE-n〔n 代表环氧乙烷（EO）数，为 13、16、20、29〕为反应物，氨
基磺酸为硫酸化试剂，尿素为催化剂，合成了一系列三苯乙烯基苯酚聚氧乙烯醚硫酸酯盐（TSPOES-n）。利用
TSPOES-n 为分散剂制备了液体分散染料，通过粒径分析探究了液体分散染料的储存稳定性，优选储存稳定性
好的液体分散染料研究了其染色性能。结果表明，TSPOE-n 与氨基磺酸物质的量比为 1∶1.6 时，阴离子活性物
（TSPOES-n）含量均在 85%以上。分散剂 TSPOES-n 中随着 n 增大，制备的液体分散染料粒径和多分散指数（PDI）
呈先降低后增大趋势。由分散剂 TSPOES-20 制备的液体分散染料粒径为 165.9 nm、PDI 为 0.195，储存稳定性
较好。将其用于高温（130 ℃）染色时，染色匀染性好，染色后织物无需还原清洗耐摩擦色牢度仍达 4~5 级，
且染后残液化学需氧量远低于粉体分散染料。

Abstract: A series of tristyrylphenol polyoxyethylene ether sulfate salts [TSPOES-n, n represents the
number of ethylene oxide (EO), n=13, 16, 20, 29] were synthesized using tristyrylphenol ethoxylates
(TSPOE-n) as reactant, sulfamic acid as sulphating reagent and urea as catalyst. Liquid disperse dyes were
prepared using TSPOES-n as dispersant, the storage stability of liquid disperse dyes was evaluated by
particle size analysis, and the dyeing properties of liquid disperse dye with good storage stability were
investigated. The results showed that the content of anionic active substances (TSPOES-n) was above 85%
when the molar ratio of TSPOE-n to sulfamic acid was 1∶1.6. With increasing of EO number of dispersant
TSPOES-n, the particle size and particle size polydispersity index (PDI) of prepared liquid disperse dye
decreased first and then increased. The liquid disperse dye prepared by dispersant TSPOES-20 had a
particle size of 165.9 nm and PDI of 0.195, and exhibited the best storage stability. When it was used for
dyeing at high-temperature (130 ℃), the dyed fabric had good dyeing levelness property, its color
fastness to rubbing could still reach 4~5 grades after dyeing without reduction cleaning, and the chemical
oxygen demand of residual liquid was much lower than that of powder disperse dye.
