Green Oxidation of Borneol to Camphor Abstract: This lab converted borneol to camphor using a green oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol

Rearrangements of the product are possible during the SN1 mechanisms‚ but not for SN2 mechanisms. This lab will examine the reaction of 1-propanol and 2-pentanol with NaBr in H2SO4‚ in which the H2O acts as the leaving group and Br as the attaching nucleophile (1). After the reaction has taken place through reflux and distillation‚ the product is able to be examined through NMR and IR spectroscopy analysis. Finally‚ these graphs will help in determining the products of each reaction and the type of

Bioquímica Repaso Examen 1 Chapter 1: Introduction to Biochemistry 1.1 Biochemistry is a Modern Science • By synthesizing urea‚ Friedrich Wöhler showed that compounds found in living organisms could be made in the laboratory from inorganic substances. He used the inorganic compound ammonium cyanate. • Two major breakthroughs in the history of biochemistry are especially notable: o Roles of enzymes as catalysts o Roles of nucleic acids as information carrying molecules.

22-2-96 CONDUCTING POLYMERS By Colin Pratt INTRODUCTION Until about 30 years ago all carbon based polymers were rigidly regarded as insulators. The idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed‚ plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer known

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

Zinc Reacts with Vinegar’s Acetic Acid To Produce Electricity March 7‚ 2014 Abstract This research is about the chemical reaction of zinc with acetic acid to produce a short amount of electricity. Even though it only conducts a small amount of voltage‚ we investigated and experimented on how it can produce more than usual without adding any other components on the project except zinc‚ copper‚ vinegar‚ or a unique container that can increase the voltage of our product. The zinc can produce
