4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared and warmed in a 25mL beaker. Benzil

Sample Abstracts As global climate change becomes a large-scale international issue‚ many proposals and methods have been suggested to combat the sharp increase in carbon dioxide (a greenhouse gas). Carbon capture and storage or sequestration (CCS) is one method currently used and studied in the United States. There are three steps to this method: capture‚ transport‚ and storage. Conceptually‚ the technology is simple: carbon dioxide is captured‚ compressed‚ and transported (via pipelines)
