Abstract:
A reaction apparatus for producing polyethylene glycol dinitrate (PEGDN) in a continuous manner includes a series of reaction cells spatially disposed in one or more planar structures and a separation arrangement for separating PEGDN and Ammonium Nitrate, in a continuous manner. The separation arrangement is a thin film evaporator and/or falling film evaporator. The plurality of reaction cells includes a feed preparation section having feedstreams for continuously providing an acid composition and a glycol composition to reaction cells. The plurality of reaction cells further includes a nitration section, where the acid composition and the glycol composition react to generate a reaction composition, and a quench and neutralization section, having feed for cooling arrangement and a plurality of feeds for providing an alkaline composition to at least partially neutralize reaction composition. The acid composition includes a mixture of dilute nitric acid and concentrated sulphuric acid.

Claim (Index 9):
The reaction apparatus of  claim 1 , wherein the feed for the cooling arrangement uses a coolant applied to a region which is spatially adjacent to the series of reaction cells.
