Abstract:
An IR spectroscopic study has established that in water-dichloroethane equilibrium solutions, carbamoylphosphine oxide forms only one complex with HNO3, R'R2P=O...HNO3, whereas with HClO4 it forms a number of solvation-separated ion pairs (IP). The structure and composition of the cation moiety of these IP depends on the molar ratio CCMPO CHCIO4 and the solution preparation temperature. A CMPO:HClO4 = 2:1 complex is formed when CCMPO/CHCIO4 > 2; for CCMPO/CCHCIO4 <2, 1:1 and 1:2 complexes and a complex with HClO4 attached to the tertiary nitrogen of CMPO are formed. A detailed discussion is given for all complexes. It is shown for the first time that H+ can interact with three oxygen atoms of two P=O groups and one C=O group (or a water molecule) at once. In the absence of CMPO, dichloroethane extracts HNO3 in the form of micelle-like associates, whose nucleus has a solubilized HNO3 molecule in the form of a solvation-separated IP.
