摘要：
The influence of ethoxylate distribution on interfacial properties of linear and branched hydrophobe C12 and C13 alcohols is examined at the air-water, decane-water, and Teflon-water interfaces. In the polydisperse ethoxylates, the presence of unreacted alcohol and broad ethoxylate distribution causes interfacial properties to change significantly at the decane-water interface and moderately at the Teflon-water and air-water interfaces. The linear hydrophobe ethoxylate is more sensitive to the presence of unreacted alcohol and broad ethoxylate distribution than the branched hydrophobe ethoxylate. © 1991.
