摘要: 以烷基二苯醚/烷基苯混合物为有机物料,采用气体三氧化硫膜式磺化工艺,制备了烷基二苯醚/烷基苯混合磺酸盐(以DL-n命名,n=3,5,7),并进行了组成分析和结构表征。测定了DL-n的静态表面张力、耐盐性、耐酸性、金属腐蚀性、净洗力,并与十二烷基苯磺酸钠(LAS)、十二烷基二苯醚双磺酸钠(MADS)进行对比。结果表明:LAS的临界胶束浓度(cmc)与cmc时的表面张力都低于DL-n系列与MADS;耐盐性、耐酸性随着混合磺酸盐中MADS含量的增多而增强;随着混合磺酸盐中MADS含量的增加,DL-n溶液对LY12-BC2硬铝、Z30一级铸铁、铜片金属腐蚀性无显著影响,DL-n对45号钢、镁片的腐蚀性低于LAS;随着混合磺酸盐中MADS含量的增加,DL-n对人工油污的净洗力无显著变化,对抗氧防锈液压油与拉伸油的净洗力逐渐降低。

Abstract:

The static surface tension, salt resistance, acid resistance, metal corrosion, and detergency of alkyl diphenyl ether/alkyl benzene mixed sulfonates (denoted as DL-n, where n=3, 5 and 7; take n=3 as an example, it refers to the mass ratio of alkyl diphenyl ether in raw material is 30% while the mass ratio of alkyl benzene is 70%) were evaluated. The results of DL-n were compared with those of sodium dodecylbenzene sulfonate (LAS) and sodium dodecyldiphenyl ether disulfonate (MADS). It was found that, among the DL-n series, LAS and MADS, LAS exhibited the lowest critical micelle concentration (cmc), the lowest surface tension at cmc, and the worst acid resistance. The salt resistance and acid resistance of DL-n were improved as the alkyl diphenyl ether content in raw material was increased. There was no significant difference among the DL-n series in metal corrosiveness to duralumin alloy LY12-BC2, Z30 grade 1 cast iron, and copper sheet, or in the detergency for artificial oil stains. The corrosiveness of DL-n to 45# steel and magnesium sheet was lower than that of LAS. The detergency of DL-n for anti-oxidation rust-preventive hydraulic oil and drawing oil decreased as the alkyl diphenyl ether content in raw material was increased. The DL-n series showed potential for use in processes with strong acidity and for industrial cleaning of 45# steel.

Key words: mixed sulfonates, salt tolerance, acid resistance, corrosiveness, cleaning power, industrial cleaning
