Conclusions

  1. 1.

    The kinetics of the interaction of triethyl phosphite with 2-diethylaminomethyl-6-methylphenol in Tetralin and dimethylformamide were studied at various mole ratios of the reagent. The rate constants were determined, and it was shown that the reaction studied obeys a first-order equation.

  2. 2.

    A deviation from additivity is observed for the index of refraction, density, and heat capacity of mixtures of 2-diethylaminomethyl-4-methylphenol with triethyl phosphite as a function of their composition on composition versus property diagrams.

  3. 3.

    It was hypothesized that the limiting step of the reaction studied is monomolecular decomposition of the complex of phenolic Mannich bases with phosphite, of the solvate type.
