SynthesisDicyclopentadienone
NANOTECHNOLOGY REVOLUTION
The use of nanotechnology
Nanotechnology, basically, deals with controlling and modifying matter at molecular and atomic scale. The physical properties of matter change dramatically as its surface to area ratio is increased to nano scales. For instance, the elements that are known to be inert start functioning as catalyst. Similarly, materials develop unique colloidal properties, solubility capacity and electrical properties. Such materials find a wide variety of application in fields as diverse as electronics, medicine and energy production.
CATALYSIS
Catalysis is the process by which the rate of a chemical reaction is increased by means of the addition of a species known as a catalyst to the reaction.
There are two type of catalyst, the heterozygous and the homozygous in this experiment, the catalyst that we chose to use is a heterozygous. Which is a insoluble and a easy to separated catalyst.
TYPE OF CATALYST
Homogeneous • Insoluble
• Hard to separated
• Use low T and P
• High selectivity
• Easy to modify
Heterogeneous • Insoluble
• Easy to separated
• Use high T and P
• Poor selectivity
• Difficult to modify
-OBJECTIVES
• Want to synthesize dicyclopentadienone.• Study the results of the catalyst, to see if a reactions occur or not.• Purify by using chromatography.

•Fe-B(OH)3 0.0575 g•KOH
0.0421 g•2-aminothiophenol 54 μlit•H2O 15 ml•EtoAc•Hexane
Procedure:1.weight the ferroceneboronic acid (0.0575g) the substrate of KOH is 0.0421g weight the 2-aminothiophenol substrate 54 ml2. put the ferroceneboronic acid into a beaker then follow by the KOH into the same beaker.3.add 15ml of H2O into the same beaker.4.Use magnetic bar to stir with 80°C5. take the chemical out6. put the solution in a separation funnel.7. separate until the solution is pure8. After ,use the chromatography with the solution, substrate and product.9. check the results with NMR
Conclusion: the result shows that nothing happen in this experiment
