Synthesis of Benzoin Date of Experiment: 1-26-15 Chelsea Price Lab Partner: Joey Simmons Abstract: In this experiment‚ benzoin was synthesized from benzaldehyde‚ using thiamine hydrochloric acid as a catalyst. The thiamine HCl was deprotonated by sodium hydroxide and acted as a nucleophile to attack the benzaldehyde. A water-cooled condenser was used to heat the solution at reflux. Vacuum filtration was used to wash and dry the product. The benzoin product was recrystallized

The Synthesis of Alkenes: The Dehydration of Cyclohexanol Adam Ohnmacht CHEM 0330 Scott Caplan 10/30/12 Abstract: In Organic Chemistry‚ many different methods are used to synthesize organic compounds from various components. In this lab‚ cyclohexanol was dehydrated to cyclohexene through an elimination reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used.

The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3‚ Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product

The Grignard Synthesis of Triphenylmethanol Organic Chemistry Lab II March 19‚ 2012 Abstract The purpose of this experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm

nanoparticles have unique properties which help in molecular diagnostics‚ in therapies‚ as well as in devices that are used in several medical procedures. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. The problem with the chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto them. To overcome this‚ the biological method provides a feasible alternative. The major biological systems involved in this are
