Heptane-1,7-diaminium dinitrate
In the title molecular salt, C(7)H(20)N(2) (2+)·2NO(3) (-), the crystal structure exhibits an unusual back-to-back paired double-stacked packing arrangement culminating in an overall double zigzag pattern of the dications. The nitrate anions form a ring around one pair of double-stacked dications. An intricate three-dimensional N-H⋯O and N-H⋯(O,O) hydrogen-bonding network exists in the crystal ...
متن کاملVolatile constituents of Pinus roxburghii from Nepal
BACKGROUND Pinus roxburghii Sarg. Is one of 3 species of pine found in Nepal, the oil of which is traditionally used to treat cuts, wounds, boils, and blisters. OBJECTIVE To obtain, analyze, and examine the anti-microbial and cytotoxic activities of the essential oils of P. roxburghii. MATERIALS AND METHODS Three plant parts (cone, needle, and bark) of Pinus roxburghii were collected in Bir...
متن کاملHeptane-1,7-diaminium sulfate monohydrate
The crystal structure of the title compound, C(7)H(20)N(2) (2+)·SO(4) (2-)·H(2)O, is presented, with particular focus on the packing arrangement in the crystal structure and selected hydrogen-bonding inter-actions that the compound forms. The crystal structure exhibits parallel stacking of the diammonium dication in its packing arrangement, together with inorganic-organic layering that is typic...
متن کاملObservations of soot during droplet combustion at low gravity: heptane and heptane/monochloroaIkane mixtures
Experimental observations of the combustion of sooting fuel droplets, performed in a drop tower to create a low gravity environment, are reported. Free n-heptane droplets and suspended droplets of heptane. monochloroalkanes. and mixtures of monochloro-octane and heptane were studied. Initial droplet diameters ranged from 0.4 to I. 1 mm. The results suggest that soot may influence droplet vapori...
متن کاملAcid-bath Phosphorylation in Heptane-extracted Chloroplasts.
When spinach (Spinacia oleracea) chloroplast fragments were lyophilized and extracted with n-heptane, acid-bath phosphorylation was significantly reduced. Phosphorylation could be restored to these chloroplasts, if the extracted material (containing quinones, carotenoids, and other lipids) was added back to dry preparation before rehydration. The results reported suggest it was not quinones whi...
