Some alkylnaphthalene and alkylphenanthrene sulfonates were synthesized by means of a Wurtz–Fittig reaction. The HLB values for the prepared compounds were calculated, and the basic properties were studied in water at different temperatures, namely, 25, 35 and 45 °C. Through surface tension measurements, the following values were determined: the critical micelle concentration (CMC) and the surface
一些烷基萘和烷基菲磺酸盐是通过Wurtz-Fittig反应合成的。计算了所制备化合物的HLB值,并在25、35和45°C的不同温度下的水中研究了其基本性质。通过表面张力测量,确定以下值:临界胶束浓度(CMC)和CMC处的表面张力(γCMC)。计算出以下值:CMC处的每分子面积(A CMC),胶束化的标准自由能变化(ΔG mic),吸附的标准自由能(ΔG ad),以及表面活性剂降低表面张力(pC20)的效率。此外,还测量了合成化合物的分配系数。结果表明,Ñ -alkylnaphthalene和Ñ -alkylphenanthrene表面活性剂表现出研究期望的性质可以在一些领域如去垢是有价值的。为了证实所制备的表面活性剂的去污力,进行了一些泡沫研究。
