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.

Extraction and analysis of two compounds from unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119

As Husserl states‚ ". . . the spatial object has infinitely many ways [to be given in the original] since it can appear in the Now‚ that is‚ in an original way from its different sides" (ACPAC553). This means a spatial object must necessarily appear from a side however‚ that side itself‚ which makes up the genuine content of the Now phase of perception‚ does not constitute the entire object. The sides exhibited point beyond themselves to other sides which

4/27/11 SYNTHESIS AND CHEMILUMINESCENCE OF LUMINOL Abstract: Chemiluminescence occurs in nature and can be found in everyday products. For example‚ the light omitted by fireflies‚ deep sea fish and glow sticks is a result of this process. Luminol was synthesized from from 3-nitrophthalic acid and then combined with potassium ferricyanide and hydrogen peroxide to omit a blue light. The product of this reaction is very unstable and is made by losing a nitrogen and the electrons go from an excited
