Abstract
ABSTRACT Sodium mono(2,4,4'-trirnethylpentyl)phosphinate has been obtained as a main product with good yield from the reaction between diisobutylene and sodium hypophosphite. The procedure is defined by a set of operating conditions which enable obtaining the product with optimum yield. Empirical relationships between the product quality and the operative conditions have been found. The purity of the mono(2,4,4',trimethylpentyl)phosphinic acid was checked by 1R and 31P NMR spectroscopy and determined by potentiometric titration of an ethanol/water solution. Finally the critical micelle concentration of sodium mono(2,4,4'-trunethylpentyl)phosphinate and sodium mono(n-octyl)phospninate has been determined.
