Chemoselective O-acylation of hydroxyamino acids and amino alcohols under acidic reaction conditions: History, scope and applications
Kristensen, Tor Erik (2015)Amino acids, whether natural, semisynthetic or synthetic, are among the most important and useful chiral building blocks available for organic chemical synthesis. In principle, they can function as inexpensive, chiral and ... -
Curing of Glycidyl Azide Polymer (GAP) diol using isocyanate, isocyanate-free, synchronous dual, and sequential dual curing systems
Hagen, Trond Heldal; Jensen, Tomas Lunde; Unneberg, Erik; Stenstrøm, Yngve; Kristensen, Tor Erik (2015)Glycidyl azide polymer (GAP) is an important energetic binder candidate for new minimum signature solid composite rocket propellants, but the mechanical properties of such GAP propellants are often limited. The mechanical ... -
Evaluation of safety distances for storage of explosive materials using a combination of thermochemical computations and CFD
Fossum, Hannibal Eie; Osnes, Andreas Nygård; Kristensen, Tor Erik (2019-01-14)A novel approach to calculating TNT equivalencies and safety distances for explosives, using a combination of thermochemical computations and computational fluid dynamics, is presented. This enables the estimation of safety ... -
A factual clarification and chemical-technical reassessment of the 1921 Oppau explosion disaster - the unforeseen explosivity of porous ammonium sulfate nitrate fertilizer
Kristensen, Tor Erik (2016-10-04)The Oppau factory was a chemical production facility constructed by the leading German chemical company BASF in the time period shortly before the First World War. The facility was located along the river Rhine, a few ... -
Safe storage of ammonium nitrate products –scientific framework for government regulations
Kristensen, Tor Erik; Osnes, Andreas Nygård (2022-10-27)Ammonium nitrate (AN) is a solid chemical compound of paramount significance in the field of agriculture, as a high-nitrogen fertilizer component, and in the formulation of blasting explosives having major civilian ... -
Smokeless GAP-RDX Composite Rocket Propellants Containing Diaminodinitroethylene (FOX-7)
Jensen, Tomas Lunde; Unneberg, Erik; Kristensen, Tor Erik (2017)Composite rocket propellants prepared from nitramine fillers (RDX or HMX), glycidyl azide polymer (GAP) binder and energetic plasticizers are potential substitutes for smokeless double-base propellants in some rocket motors. ... -
Synthesis and characterization of Al@MOF materials
Langseth, Eirin; Swang, Ole; Arstad, Bjørnar; Lind, Anna Maria; Cavka, Jasmina Hafizovic; Jensen, Tomas Lunde; Kristensen, Tor Erik; Moxnes, John Fredrik; Unneberg, Erik; Heyn, Richard H. (2019)The potential impregnation of Al(0) nanoparticles in the pores of three different metal-organic frameworks (MOFs), MIL-53-Al, HKUST-1, and UiO-67, was investigated through the suspension of the MOFs in AlH3•NMe2Et (1), ... -
Synthesis of nitroxyethylnitramine (NENA) plasticizers and dinitroxydiethylnitramine (DINA) in continuous flow**
Fredriksen, Kim Alex; Kristensen, Tor Erik (2023-03-05)Nitroxyethylnitramines (NENAs) and dinitroxydiethylnitramine (DINA) are useful energetic plasticizer components in propellants and explosives. However, their synthesis at large scale can be delicate because it involves two ...
