Dehydroabietates with poly(ethylene oxide) chains of average m=12, 17, and 45 units [DeHab(E) m ] were synthesized. The adsorption at the liquid-vapor interface was measured, and the adsorbed amount and critical micelle concentrations (CMC) were dete

The synthesis and characterization of novel surfactants derived from tall oil fatty acid methyl esters are presented. The tall oil fatty acid methyl esters, which mainly contain methyl oleate, were converted to 9,10-epoxy derivatives and further tran

An improved method for the synthesis of two types of carbohydrate-based, pH-sensitive surfactants has been developed. The surfactants are formed in almost quantitative yields from d-fructose and suitable alkylamines, when using a zinc halide salt as
