.Energetic ionic liquids compared to conventional high energy compounds, such as TNT, HMX and RDX has a low vapor pressure, high thermal stability and adjustable chemical and physical properties and high being liquid range. A new class of ionic salts that have a large number of nitrogen on their structure have distinctive characteristics such as high heat of formation and high viscosity, comp...
Two data sets were collected on single crystals of hexamethylenetetramine (urotropin) using a fourcircle diffractometer with Cu K~ radiation and an imaging-plate two-dimensional detector with Mo K~ source using the rotation method. Both data sets extend to the same limit of sin 0/2 = 0.62A -~, corresponding to a resolution of 0.81 ,&. Different processing protocols were employed for the two set...

In the course of our continuing study on the positional effect of five-membered monoheteroaromatic compounds, we were in need of 3-thiophenecarboxylic acid (2a). Although 2a is commercially available, the price is about 70 times more expensive than the 2-isomer (4a). Therefore, ...
