摘要
New nonionic surfactants were synthesized through esterfication of a dicarboxylic acid (succinic or adipic acid) with fatty alcohols that have different molecular weight; namely, octyl, lauryl, and cetyl alcohol. The ester products were reacted with polyethylene glycols of different molecular weight (400, 600, and 1,000) to form compounds having different hydrophil-lipophil balances. The surface active properties of the prepared surfactants were evaluated, and the critical micelle concentrations were determined, so as to determine the Pc20, effectiveness cmc, and maximum dispersion efficiency from the screening study.
