According to Figure 4 and 5‚ the moles of Cu initially obtained and at completion‚ differentiated. It was evident that the initial moles of Cu (0.0254)‚ did not regenerate all the amount‚ as 0.0124 moles of Cu was attained. In regards to this‚ the no. moles that was eliminated was approximately‚ 0.013. Respectively‚ in Figure 3‚ a large deviation amongst the initial and final quantity of copper‚ this implies that the rest of the mass that had diminished‚ was greater than the final product. These

Microwave Synthesis of 5‚10‚15‚20- Tetraphenylporphyrin Abstract: In this green chemistry experiment of 5‚10‚15‚20-tetraphenylporphyrin was synthesized from benzaldehyde and pyrrole. using microwave irradiation to heat the reactants.‚ The liquid reactants are absorbed on a solid support‚ silica gel‚ which acts as a Lewis acid catalyst to facilitate the reaction. The reaction forms a porphyrinogen‚ which is then oxidized to the porphyrin product by atmospheric oxygen. Column chromatography is performed
