Abstract

Surfactants (C9H19·C6H4·O· (CH2) 3·SO3Na, C9H19·C6H4· (OC2H4) n·O· (CH2) 3·SO3Na) having propane sulf onate group were prepared from nonylphenol and polyoxyethylene nonylphenol ethers (n =2.7, 6.0, 7.6, 11.2, 13.6, 15.4).<BR>Surface active properties in their aqueous so were examined f o rsurf ace tension, foaming-, penetrating-, emulsifying powers, hard water resistance, Krafft point and cloud point.<BR>In general, the propane sultone derivatives exhibited excellent solubility, foaming power and hard water resistance, but surface tension was inferior than polyoxyethylene nonylphenol ethers (n=7.6, 13.6) and dodecylbenzene sulfovate.<BR>The relationships between the surface active properties and the length of the ethylene oxide chain in the propane sultone derivatives were as follows :<BR>(1) Favorable foaming power, penetrating power and surface tension were exhibited by the propane sultone derivatives containing 0 to 6 moles of the ethylene oxide chain.<BR>(2) Superior emulsifying power was shown by the propane sultone derivatives containing 10 to 13 moles of the ethylene oxide chain.<BR>(3) All propane sultone derivatives having the ethylene oxide group showed excellent hard water resistance.
