SENSITIVITY FUNDAMENTALS
Abstract
The conventional gap test was used to investigate the importance of confinement material and geometry on the low velocity detonation (LVD) shock sensitivity of the difluoroamino compounds. Photographs show that several initiation mechanisms influence the conventional gap test. These mechanisms are discussed in terms of confinement geometry and material as well as initial shock input. Concepts of transient detonation phenomena in the simple difluoroamino liquids underwent a change during the past six months. Adiabatic explosion theory is still basic for failure on liquids, but the concept apparently must be applied in a new way. Failure diameter studies on IBA and 2,3-DB have been completed, and the importance of dark waves in 1,2-DP has been partially elucidated. In the kinetic studies of dehydrofluorination of NF compounds in aqueous solution, rates and activation parameters have now been determined for 1,3-DP, 1,2,2-TP, and 2,2,3-TB in 30% diglyme-70% water between 50 and 75 C. To date, eight bis and tris propanes and butanes have been examined. Studies have also been initiated on the photolysis of NF compounds. Preliminary results for t-BD are available. A detailed kinetic study of the decomposition of t-butyl difluoramine via VLPP has been carried out.
