烷基二苯醚/烷基苯混合磺酸盐在工业清洗中的应用
Application of alkyl diphenyl ethers/alkyl benzene mixed sulfonates in industrial cleaning
摘要
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.关键词
