  2. 1. A nuclear magnetic resonance study of dialkyldithiophosphate complexes : polycrystalline and surface adsorbed

    Author : Anna-Carin Larsson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : 31P, 13C and 207Pb NMR were used to characterize different metal (Ni, Zn, Pb) dialkyldithiophosphate complexes. Eight different sodium or potassium dialkyldithiophosphate salts (alkyl groups R=ethyl-, n-propyl, iso-propyl, n- butyl, iso-butyl, sec-butyl, iso-amyl and cyclo-hexyl) were used as starting materials.
