<p>PURPOSE:To obtain a surfactant having a large defoaming rate, by containing sulfonate of a trimer-pentamer of butylene as a main component. CONSTITUTION:Sulfonate of polybutylene being a trimer-pentamer of n-butylene, iso-butylene or a mixture thereof is used a main component. As a salt of sulfonic acid, an alkali metal salt, an alkaline earth metal salt, an amine salt or an ammonium salt are designated. In preparing a surfactant, alkylbenzenesulfonate or ethylene oxide adduct of phenols can be appropriately added other than the above-mentioned main component.</p> |
