Abstract
The present invention provides for a system comprising a static reactor vessel which requires no moving parts, and adapted for precise control of reaction processing parameters including temperature, pressure, and flow rate; a mechanism for settling of the product phase from the salt ammonia phase and removing a significant portion of the ammonium chloride waste material; a method for recovering essentially all of the process ammonia and a method for maintaining a reaction environment which is suitably ionic/acidic.
