    Notes: This paper reports on a comprehensive literature search and small scale experimental work on the reaction characteristics of phosphorous trichloride and water. More than 30 tests were conducted, including both closed and open test cells. The water to phosphorus trichloride molar ratio was varied from 1 to 25. When in contact, water and phosphorus trichloride will form two liquid layers with a reaction starting at the interface. The impact of variables on reaction rates including the interface surface area, layer depth, and stirring were investigated experimentally. A reaction rate model that fits all the measured data is presented. Case studies illustrating the use of this data for emergency relief systems and vent containment design are presented in reference.

    Notes: The NMR. spectra of the five monomethylazulenes and of some polysubstituted azulenes, as well as those of their conjugate acids (azulenium cations), are recorded. It is shown that protonation of azulenes lacking C2v symmetry leads to a tautomeric equilibrium of two conjugate acids. The position of this tautomeric equilibrium is in essential agreement with the one previously predicted from the UV. spectra on the basis of a MO treatment.
