Synthesis of Salicylic Acid from Wintergreen Oil Objective – Preparation of salicylic acid (organic synthesis) from methyl salicylate utilizing previously used procedure from the nineteenth century. The final product will then be evaluated in comparison to salicylic acid made from benzene. Discussion – In this synthesis‚ methyl salicylate is the starting material or precursor and salicylic acid is the target product. It is the major constituent of wintergreen oil. The difference in structures

Protein and Amino Acid Supplementation in Sports The popularity of increasing the “performance-enhancing” supplements‚ Protein and amino acids‚ has flourished among all athletes. This increase is attributed to the belief by many of the athletes that it provides endurance‚ strength and speed enhancement. Amino Acids (AA) enhanced physical feats‚ improved energy and recovery sooner from fatigue. The three vital Amino Acids which were given a high focal point among athletes are leucine‚ isoleucine

#04: Synthesis of Salicylic Acid from Wintergreen Oil I. Introduction and Purpose Until 1874 commercial salicylic acid was synthesized entirely from natural wintergreen oil. In this experiment the salicylic acid is reproduced using methyl salicylate‚ the major constituent of wintergreen oil and later compared to salicylic acid made from benzene. The purpose of this lab is to determine the difference between salicylic acid made from methyl salicylate and salicylic acid made from benzene comparing

concentrain of sulphuric acid Aim The point of this investigation is to find out the concentration of the sulphuric acid in my experiment. I will do this by titrating the sulphuric acid with sodium carbonate. H2SO4 + Na2CO3 à Na2SO4 + H2O + CO2 Acid + Alkali à Salt + Water + Carbon dioxide Ratio of sulphuric acid to sodium carbonate: H2SO4 : Na2CO3 1 : 1 Concentration of sulphuric acid: H2SO4 is approximately 0.05 - 0.15 moldm-3 The average concentration of the sulphuric acid is: 0.05 + 0.15 =

These attacks are often referred to as the 9/11 attacks‚ they were a series of attacks of terror against the United States. Two planes flew into the World Trade Center’s twin towers‚ some of the most tallest and best buildings in New York City. Another plane hit the pentagon‚ and the third crashed in Pennsylvania‚ as on this one‚ there were no survivors. American Airlines Boeing 767 with over 20‚000 gallons of jet fuel crashed into the north tower of our World Trade Center. This left a huge burning

materials. So where would Japan get their resources to continue the war now? The Japanese High Command carefully discussed this and came up with the conclusion that the Dutch East Indies would be the best place to gain resources. But they knew that an attack on the Dutch East Indies would probably bring the US into the war. So they had to find a way to prevent the US from fighting with them until they conquered the Dutch East Indies. That’s when they planned Pearl Harbor. The goal of Pearl Harbor was
