DEVELOPMENT STUDY FOR IMPROVEMENT OF THE MANUFACTURING PROCESS FOR TRIETHYLENEGLYCOLDINITRATE (TEGDN)
Abstract
Studies initiated to improve the manufacturing process of triethyleneglycoldinitrate (TEGDN), included a literature survey, chemical kinetic considerations, process variables such as temperature, concentration of reactants and reaction times, recovery of spent acid, and process economic considerations. General pilot plant equipment design and criteria for materials of construction are also to be established. A versatile nitration apparatus was designed and built for the study of the TEGDN reaction. The reactor consists of an interchangeable stainless steel beaker with a 1/4-in. pipe welded to the bottom. The reactor sets in a larger brine jacket which cools the reaction. Systems were explored with reactant concentrations close to those described by Auberstein (Chem. Abstr., 45:353i, 1951) as optimum for the production of TEGDN. A study was made of the spent acid stabilization and recovery from TEGDN reactions. A stabilization process was developed which resulted in a product which can be stored indefinitely at 60 to 80 F or heated for removal of the HNO3 fraction in a recovery unit.
