A series of branched dodecyl phenol polyoxyethylene ethers (b-DPEO ) were successfully synthesized alkylation and ethylene oxide addition reactions. The alkylation reaction was conducted by using a branched internal olefin as the raw material. Furthermore, the conversion rate of the branched dodecene was measured to be 98.1% and the selectivity towards branched dodecyl phenol (b-DP) was 95.9%. Moreover, b-DPEO (b-DPEO, b-DPEO, b-DPEO) were obtained the reaction of ethylene oxide with b-DP. Notably, b-DPEO can efficiently reduce the surface tension of water below 31.55 mN m at the critical micelle concentration (cmc) and the cmc value in water was approximately 1.3 × 10 g L at 25 °C. The preferable wetting ability of b-DPEO was superior to that of commercialized dodecyl phenol polyoxyethylene ether (c-DPEO ), so it will be promoted and used in the textile and pesticide industries.
通过烷基化和环氧乙烷加成反应成功合成了一系列支链十二烷基酚聚氧乙烯醚（b-DPEO ）。烷基化反应以支链内烯烃为原料进行。此外，测得支链十二碳烯的转化率为98.1%，对支链十二烷基酚（b-DP）的选择性为95.9%。此外，通过环氧乙烷与b-DP反应得到了b-DPEO （b-DPEO、b-DPEO、b-DPEO）。值得注意的是，在临界胶束浓度（cmc）下，b-DPEO能有效地将水的表面张力降低至31.55 mN m以下，在25℃时其在水中的cmc值约为1.3×10 g L。b-DPEO较好的润湿能力优于商业化的十二烷基酚聚氧乙烯醚（c-DPEO ），因此它将在纺织和农药行业得到推广应用。
