SODIUM MONO-OCTYLPHDSPHINATES, SYNTHESIS, PURIFICATION AND SURFACTANT PROPERTIES

Abstract
Sodium hypophosphite can be added to terminal hydrocarbon double bonds under specific conditions, according to a Free radical mechanism. The direct reaction using sodium hypophosphite produces sodium monaoctylphosphinate as the main reaction product, and the amount of dimer compound obtained is almost unsignificant. The reaction has been applied using 1-octene and, after purification of the monomer and dimer as acid compounds, the reaction yields have been determined. Surfactant properties, such as surface tension, wetting power and foaming power of the pure sodium monocctylphosphinate have bean measured.
