Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)

Synthesis With all the foreigners crossing the borders of the United States‚ America is considered to be a nation of immigrants. The United States has all kinds of immigrants who decide to relocate to America in order to pursue better opportunities for themselves than what they could find in their own country. Once the immigrants make it passed American borders‚ they begin living the "American way"‚ and doing what they think will help lead to a positive movement within the community. What the

Experiment 8: Synthesis of Adipic Acid Performed November 8th & 10th By Jennifer Seitz Organic Chemistry 344 Section 803 Fall 2011 Objective: The purpose of this experiment was to synthesize adipic acid from cyclohexanol via an oxidation reaction that was catalyzed by sulfuric acid. Purity of the product was assessed by measuring the melting point. Physical Properties/Structures: Name | Formula | Molecular Weight (g/mol) | Boiling Point (0C) | Melting Point(0C) | Density(g/mL)

Synthesis of Methyl Stearate The purpose of this lab was the convert liquid methyl oleate to solid methyl stearate by catalytic hydrogenation. Firstly‚ we produced hydrogen gas using solid mossy zinc and sulfuric acid. Using the hydrogen produced in the previous reaction‚ we were able to convert the liquid methyl oleate to solid crystals of methyl stearate. A mineral oil was also used to bubbler was used to maintain the hydrogen pressure slightly above the atmospheric pressure and to prevent back-diffusion

THE SYNTHESIS OF MONSTER INC. In Monsters Inc. At the beginning of the story‚ depicted a company belonging to the monsters that find and produce energy from the screams of children being made afraid by them. They’re harvesting energy to keep from becoming extinct by going back to when humans were most prominent. Monsters must have relied on anti-human instincts to believe that just touching a human would corrupt their world like it did in the past. So they scare humans to gather their energy until
