Commercial interest in perchlorates began in the late 1890s/early 1900s in Europe and the United States as a direct result of the pioneering efforts in rockets and their propulsion systems (Mendiratta et al. 1996). The production of ammonium perchlorate, the largest component of solid rocket propellants, far outpaced that of the other perchlorates listed in Table 4-1. Their commercial manufactu...
متن کامل(1,4,7,10-Tetraoxacyclododecane)(trideuteroacetonitrile)lithium perchlorate
In the title compound, [Li(C(8)H(16)O(4))(CD(3)CN)]ClO(4), the Li atom is penta-coordinate. The O atoms of the 12-crown-4 ether form the basal plane, whereas the N atom of the trideutero-aceto-nitrile occupies the apical position. The Li(+) atom is displaced by 0.794 (6) Å toward the apical position from the plane formed by the O atoms because the Li(+) atom is too large to fit in the cavity of...
متن کامل4-Bromo-3-methylanilinium perchlorate 18-crown-6 clathrate
The reaction of 4-bromo-3-methyl-anilinium perchlorate and 18-crown-6 in methanol solution yielded the title compound, C(7)H(9)BrN(+)·ClO(4) (-)·C(12)H(24)O(6). The protonated 4-bromo-3-methyl-amine unit contains one -NH(3) (+) substituent, resulting in a 1:1 supra-molecular rotator-stator structure, (C(7)H(9)Br-NH(3) (+))(18-crown-6), through three bifurcated N-H⋯(O,O) hydrogen bonds between t...

Mycobacterium leprae (M. leprae) as alternative to current WHO MDT. Individual drugs tested were Rifampicin (RMP), Rifapentine (RPT) and Moxifloxacin (MOXI). Drug combinations were RMP, Clarithromycin (CLARI), Minocycline (MINO) and RMP, MINO and Ofloxacin (OFLO). RPT drug combinations were RPT, CLARI, MINO and RPT, OFLO, MINO. Both the drugs and drug combinations were used as daily regimen and...

In the title mol-ecular salt, C(18)H(15)ClNO(+)·ClO(4) (-), the quinolin-ium ring system is approximately planar, with a maximum deviation of 0.027 (1) Å. The dihedral angle formed between the mean planes of the quinolinium ring system and the benzene ring is 78.46 (3)°. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the cations and anions into a three-dimensional...
