Bis[2-(2-pyridylsulfanyl)ethyl]ammonium perchlorate

open access: yesActa Crystallographica Section E, 2010
The cation and anion of the title salt, C14H18N3S2+·ClO4−, lie on a twofold rotation axis. The cation is a W-shaped entity with the aromatic rings at the ends; the ammonium NH2+ group is a hydrogen-bond donor to the pyridyl N atoms ...

The thermal decomposition behavior of ammonium perchlorate and of an ammonium-perchlorate-based composite propellant [PDF]

open access: yes, 1998
The thermal decomposition of ammonium perchlorate (AP) and ammonium-perchlorate-based composite propellants is studied using the simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) technique. The main objective of the present work is to evaluate whether the STMBMS can provide new data on these materials that will have sufficient ...

Combustion Response of Ammonium Perchlorate [PDF]

open access: yesAIAA Journal, 2000
A modified Price–Boggs–Derr model is applied to compute the linear and nonlinear combustion response properties of monopropellant ammonium perchlorate (AP). The kinetics constants were changed to achieve good agreement with response function data as well as with steady-state data.The numerical method was first validated with the classical theory ...

Photooxidation Coupled Kabachnik–Fields and Bigenelli reactions for Direct Conversion of Benzyl alcohols to α-Amino Phosphonates and Dihydropyrimidones.

open access: yesActa Chimica Slovenica, 2020
A tandem one-pot solvent free approach for the direct conversion of benzyl alcohols to α-amino phosphonates and dihydropyrimidones is reported. The method relies on a metal free photo-oxidation of benzyl alcohols to benzaldehydes under UV irradiation ...

THE EFFECT OF AMMONIUM PERCHLORATE ON MILK PRODUCTION AND BLOOD PICTURE OF FREISIAN COWS [PDF]

open access: yesAssiut Veterinary Medical Journal, 1986
The effect of ammonium perchlorate supplementation in a dose of 1gm/100 kg body weight was studied on 10 Freisian cows for 5 months. Milk yield was studied and milk samples were taken to determine some milk constituents.

Polyurethanes Based on Environmentally Friendly Polyols as a Promising Alternative to HTPB Binder for Composite Propellant Rockets

open access: yesProceedings, 2023
Composite propellants used in solid-fuel rockets commonly consists of an oxidizer, the most used being ammonium perchlorate, fuels such as powdered aluminum, compounds that control the burn rate (catalysts or inhibitors), and various other additives [...]

Atmospheric origins of perchlorate on Mars and in the Atacama [PDF]

open access: yes, 2010
Times Cited: 22Isotopic studies indicate that natural perchlorate is produced on Earth in arid environments by the oxidation of chlorine species through pathways involving ozone or its photochemical products.
