Synthesis of Ammonium Dinitramide by Nitration of Potassium and Ammonium Sulfamate. The Effect of Sulfamate Conterion on ADN Purity
Nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °C. The reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). The difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. It was found that both the yield and purity of the product is better starting with potassium ...
متن کاملAmmonium Toxicity and Potassium Limitation in Yeast
DNA microarray analysis of gene expression in steady-state chemostat cultures limited for potassium revealed a surprising connection between potassium and ammonium: potassium limits growth only when ammonium is the nitrogen source. Under potassium limitation, ammonium appears to be toxic for Saccharomyces cerevisiae. This ammonium toxicity, which appears to occur by leakage of ammonium through ...
متن کاملCorrection of thiazide hyperuricemia by potassium chloride and ammonium chloride.
Large doses of KCI lowered serum uric acid while producing mild, apparently unrelated, uricosuria in four chlorothiazide-treated subjects. In two control subjects KCI also caused mild uricosuria, but had a negligible effect on serum uric acid concentration. Ammonium chloride decreased serum urate in all six subjects, while urinary uric acid excretion remained essentially unchanged. It is sugges...
متن کاملHydrothermal Synthesis of Sodium and Potassium Bismuth Titanates
A thermodynamic model of electrolyte solutions has been used as a tool for equilibrium calculations in the Na-Bi-Ti-H2O and K-Bi-Ti-H2O systems. To perform the calculations, unknown standard-state properties for Na0.5Bi0.5TiO3 (NBT), K0.5Bi0.5TiO3 (KBT) and other solid compounds that exist in these systems were established. As a result of the calculations, stability and yield diagrams of the in...
متن کاملMicrowave and Ultrasound Augmented Leaching of Complicated Zinc Oxide Ores in Ammonia and Ammonium Citrate Solutions
Recovery of zinc from low grade zinc oxide ore is attempted with ammonia and ammonium citrate solutions augmented by microwave roasting and ultrasound radiation. The influence of the ammonia-ammonium ratio, roasting temperature, ultrasound power, and leaching time were assessed on the recovery of zinc. A maximum zinc recovery of 88.57% could be achieved at a roasting temperature of 673 K, leach...
