BUTENEDIOIC ACID PRE-LAB ASSIGNMENT 1. Maleic acid is the cis version and fumaric acis is the trans version of butenedioic acid. 2. 3. See attached paper. 4. Maleic anhydride is the compound that crystalizes in part A in the experiment. 5. HCl acts as a catalyst to break one of the carbonyl group in the maleic acid which rotates the structure to form a trans structure of the butonal acid which is the fumaric acid. And it does so by donating its protons. 6. Maleic acid Chronic

EXPERIMENT 4: Synthesis of Salicylic Acid from Wintergreen Oil Abstract: The purpose of this experiment is to take methyl salicylate (wintergreen oil) and by heating it under reflux with NaOH as a solvent‚ and then cooling the mixture with H2SO4 as another solvent‚ synthesize salicylic acid. The final step involves purify the product to produce as pure a sample of salicylic acid as possible. This process allowed for the successful production of 1.406g salicylic acid‚ an 82.70% yield. The NMR and IR

Experiment 2: Centrifugation Title Centrifugation of fresh milk and Acetic Acid Objective(s): 1. To separate coagulated milk from mixture of fresh milk and Acetic Acid by centrifugation 2. To determine the relationship of speed of centrifugation with the coagulation of milk which separate from mixture. 3. To study the process of centrifugation Introduction Centrifugation is a process which materials suspended in a liquid medium undergo separation or concentrate due to the effect of gravity

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
