National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract Used ELBA solvent (Ethyl Lactate/Butyl Acetate) contaminated with components of N-5 propellant and water, was reclaimed by vacuum and ambient pressure distillation. Nitroglycerin (NG), water, and butyl acetate contents of the distillates are reported. Water separation in the distillate is discussed. Nitroglycerin content and thermal stability of the residues are reported. Distillations were performed successfully. Ninety percent recovery was obtained. Stability studies showed that the contaminated solvent could be distilled safely. (Author)
