Abstract At the time of the 1996 attempt to summit Mount Everest‚ Adventure Consultants was a four-year old company that had enjoyed financial success in spite of the death of one of its’ cofounders‚ Gary Ball. Mountain Madness‚ founded by Scott Fischer in 1984 was an older‚ but somewhat less successful‚ company. In retrospect‚ the adverse weather conditions‚ combined with logistical and other issues during the time preceding the ascent‚ combined to form a very challenging external environment for

This experiment allowed the students to conduct the synthesis of aspirin‚ acquire the skills of recrystallisation using normal filtration and reinforce the technique of the melting point determination. The method used to synthesize aspirin was esterification by reacting salicylic acid with acetic anhydride with the presence of dehydrating agent‚ conc. sulphuric acid‚ to speed up the reaction. Having obtained the crude aspirin which was still impure‚ recrystallisation was conducted to remove the impurities

Introduction Discovered by Georg Wittig in 1954‚ the Wittig reaction is a robust organic synthesis method for preparing stereospecific alkenes. In general‚ Wittig reactions involve an aldehyde or ketone and a Wittig reagent (triphenylphosphonium ylide) and result in the formation of an alkene product and triphenylphosphine oxide (side product). Stereospecific alkene products can be synthesized by adjusting the reaction reagents and conditions. In the 60 years since the Wittig reaction was discovered

bonds. Disperse blue 3 is more polar because it has a hydroxide bond and has a larger dipole. The principle behind using column chromatography is that it separates compounds based on polarity. The alumina serves to allow for a purer separation than TLC plates because it has a more polar surface than silica gel does. The less polar dye moves first because it is not as soluble in the stationary phase as the more polar dye is. The solvent was switched from methylene chloride

stressed Access-a-ride system leaves disabled riders at a huge disadvantage when it comes to travel in the city. Fortunately‚ Toyota has partnered with the Taxi and Limousine Commission (TLC) to bring the city it’s first ever rear-entry‚ ramp equipped taxi van‚ scheduled to hit he streets once it secures it’s TLC stamp of approval. The van‚ which can load a disabled passenger in under a minute‚ will not only lax the over stressed city streets but finally allow equal comfort that disabled customers

MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight
