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

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 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

Synthesis of Methyl Salicylate from Aspirin Esters are a class of organic compounds. An ester compromises an organic or inorganic acid in which one or more hydroxy (OH) groups have been replaced by and alkoxy (O-alkyl) group. For example‚ the simplest ester‚ methyl formate (CHOOCH3)‚ is made up of formic acid (CHO-OH) in which the hydroxyl group has been replaced by a methoxy group (-OCH3). Similarly‚ ethyl acetate (CH3CO-OCH2CH3) is made up of acetic acid (CH3CO-OH) in which the hydroxy group
