Heats of formation of lithium perchlorate, ammonium perchlorate, and sodium perchlorate
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961 Calorimetric measurements of the heats of solution of LiClO4(c), NH4ClO4(e), and NaClO4(c) have been made. The results have been combined with the heats of formation of KClO4(c), KCl(c), LiCl(c), NH4Cl(c), and NaCl(c), to obtain the following heats of formation: LiClO 4 ( c ) , Δ Hf ° ( 25 ° C ) = - 380.27 ± 1.21 kj / mole = - 90.89 ± 0.29 ...

Environmental forensic evidence from perchlorate in dust fall [PDF]
, 2016 Summer in Malta is accompanied by fireworks as part of the numerous (about 85) religious festivals (festa) that occur throughout the period. We attempted to establish whether firework activity is truly following official trade statistics, which imply a ...

Case Studies in Chemical and Environmental Engineering, 2021 Both perchlorate and black carbon (BC) are known for their common source of origin (i.e. burning processes, especially fireworks display), yet to our knowledge no study has focused on the effect of perchlorate (ClO4-) on the mobility of black carbon. The

Benzyltriphenylphosphonium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 The asymmetric unit of the title compound, C(25)H(22)P(+)·ClO(4) (-), contains two independent cations and two independent anions. The closest inter-molecular contact is a weak inter-molecular C-H⋯π(arene) inter-action.

Immunological detection of small organic molecules in the presence of perchlorates: relevance to the life marker chip and life detection on Mars. [PDF]
, 2011 The proposed ExoMars mission, due to launch in 2018, aims to look for evidence of extant and extinct life in martian rocks and regolith. Previous attempts to detect organic molecules of biological or abiotic origin on Mars have been unsuccessful ...
