Zi. Kuvaeva et al., ASSOCIATION, WATER SORPTION, AND IR-SPECTRA OF ORGANIC DINONYLNAPHTHALENE SULFO ACID-SOLUTIONS WITH VALINE, Colloid journal of the Russian Academy of Sciences, 56(2), 1994, pp. 134-136
The association and the water sorption by a complex of dinonylnaphthal
ene sulfo acid (ND) and valine in heptane solutions were studied as a
function of the valine content in the organic phase and of the valine
ionic form. Using IR spectroscopy an attempt was made to determine the
valine ionic form in the heptane solution of ND and to evaluate the n
ature of the valine interaction with the sulfo group.
