AI Technical Summary
Technical Problem
Existing methods for drying and cleaning aliphatic and cycloaliphatic nitrate esters are inefficient, costly, and do not effectively remove fleeting contaminants, leading to products with high water content and impurities.
Method used
A procedure involving the use of an inert gas for drying and cleaning nitrate esters, which includes a washing step followed by drying and purification using an inert gas flow-through process, effectively removing water and fleeting contaminants.
Benefits of technology
The method achieves high-purity, low-moisture nitrate esters with a significant reduction in fleeting contaminants, improving product quality and reducing processing costs and effort.

Abstract
The present invention relates to a method for drying and / or purifying, preferably drying and purifying, aliphatic or cycloaliphatic nitrate esters (esters of nitric acid), in particular for removing water and volatile and / or volatilizable impurities which are produced particularly during production and / or washing of nitrate esters, and to corresponding uses and to a corresponding apparatus and system for carrying out the method.
