Thermochemistry of heteroatomic compounds. Part 14. Enthalpies of vaporization and formation of derivatives of phosphoric and phosphonic acids

The thermochemistry of phosphorylated derivatives of methylphosphonic acid have been systematically investigated. The vaporization and formation entha lpies about fifty derivatives of phosphoric and phosphonic acids were analy sed and a number of contributions in the mentioned thrmochemical trems were created. It was shown, that the specific interaction with chloroform and pyridine is expressed only at aminophosphonates but not at hydroxyphosphonates.
