Aluminium is the most abundant metal in the world; however it can be quite expensive due to the extraction method‚ electrolysis. Aluminium ore is called bauxite‚ it is then purified into a white powder (aluminium oxide) then the aluminium can be extracted. To turn it into aluminium they heat the powder till it’s molten so electricity can pass through it. Its melting point is over 2‚000 Celsius‚ so it would therefore be quite expensive. One way of cutting costs is by dissolving it in molten cryolite

#15 Synthesis of Ethyl Salicylate from Salicylic Acid ____________________________________________________________ _______________ Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol. Yields of salicylic acid (week 1) and ethyl salicylate will be found‚ as well as the overall yield of the 2-step conversion of acetyl salicylic acid to ethyl salicylate. Introduction: Esters are formed from the reaction of acids and alcohols: O O

Fracking can be defined as a method to remove natural gas from the ground. Another way to describe fracking also known as hydraulic fracturing is the process of creating fissures in underground formations to allow natural gas to flow (Natural Gas Extraction – Hydraulic Fracturing | US EPA). This allows the gasses to leak through the cracks to be effectively captured and stored for use. The process for fracking is as follows: First they begin by drilling approximately 6‚000 feet into the ground‚ penetrating

data contained herein is my own work unless otherwise referenced. Tessa Landauer Abstract The goal of the experiment was to isolate and purify the unknown D liquid and solid by using its acidic and basic characteristics in a chemically active extraction then to identify the unknowns by analyzing the physical properties on IR and NMR spectrums. The neutral solid was purified through recrystallization and the melting point range was determined to be 47.5oC to 48.9oC. The basic liquid was purified

CHAPTER I INTRODUCTION Peel waste are highly perishable and seasonal‚ is a problem to the processing industries and pollution monitoring agencies. There is always an increased attention in bringing useful products from waste materials and citrus wastes are no exceptions. Suitable methods have to be adopted to utilize them for the conversion into value-added products [Nand‚ (1998)]. Pectin exists in varying amounts in fruit cell walls and has important nutritional and technological properties

inhibitors of growth. Today‚ there are are number of well established techniques commercially available as kits which make DNA extraction and purification easy. Although kits offer fast and reliable methods for extracting plasmid DNA with high yields‚ kits are expensive. Since a PCR is performed afterwards‚ which amplifies certain DNA fragments‚ we use miniaturized extraction methods; the extracted amount is large enough for further processing.
