nitration of Acetanilide i.e. how hydrogen on a carbon chain is replaced with a nitro group. Reagents and Chemicals: • Acetanilide (5g) • Glacial acetic acid (5mL) • Concentrated sulphuric acid (10mL &1.5mL) • Concentrated Nitric acid (2.0mL) • Methanol (30-50mL) Modification to experimental procedure: The experimental procedure was conducted as per instructions from the chemistry 220 manual. We were told to add 5grams of Acetanilide but due to time constraints I had added 5.05grams. Whilst preparing

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

ABSTRACT: LCZ696 (sacubitril/valsartan‚ EntrestoTM) is a novel therapy proposed for heart failure treatment. It was recently approved by the FDA in order to decrease the mortality rate and hospitalization for patients with chronic heart failure. So this study is considered as the first report to investigate the fluorimetric behavior of sacubitril in addition to pursuing all the different conditions which may affect its fluorescence. Numerous conditions were studied such as studying the effects of

all FeCr is produced in submerged arc furnaces‚ while the role of competitive technologies like DC is limited. In all furnaces fluxes are used to optimize the slag composition. Vital characteristics are smelting point‚ electric conductivity and viscosity. The main components of FeCr slag are SiO2‚ Al2O3 and MgO. Additionally it consists of Cr-‚ Fe-oxides and CaO. Granulated slag and/or classified slag products are produced depending on the production process. The slag products are mainly marketed

speed is much greater than the speed of sound. Aerodynamicists disagree over the precise definition of hypersonic flow; minimum Mach numbers for hypersonic flow range from 3 to 12. Most aerodynamicists use numbers between 5 and 8. The influence of viscosity in the flow dictates a third classification. Some problems involve only negligible viscous effects on the solution‚
