Dimethylamine ions, decomposition

Maleic anhydride decomposes exothermically, evolving carbon dioxide, in the presence of alkali- or alkaline earth- metal or ammonium ions, dimethylamine, triethylamine, pyridine or quinoline, at temperatures above 150°C [1]. Sodium ions and pyridine are particularly effective, even at concentrations below 0.1%, and decomposition is rapid [2]. An industrial incident involved gas-rupture of a large... 

A method developed to predict the rates of ion-molecule association reactions (Olmstead et al, 1976) was based on a quick randomization of energy in the collision complex and on treating the baekward decomposition of the collision complex by an application of the RRKM theory. The method was successfully applied to predict both the pressure dependence and the temperature dependence of the association rates of proton-bound dimers of ammonia, methylamine, and dimethylamine.
