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.

dehydration of 2-butanol yielded 4.6% 1-butene‚ 67.3% trans-2-butene‚ and 28.1% cis-2-butene‚ and a dehydrohalogenation of 2-bromobutane yielded 19.1% 1-butene‚ 69.9% trans-2-butene‚ and 11.0% cis-2-butene. Backround: Gas Chromatography separates organic samples much in the same way as column chromatography. The only differences are that it uses a moving gas phase and a stationary liquid phase‚ and that the temperature of the gas system can be controlled. In a gas chromatograph the sample is shot

Robinson Annulation Robinson Annulation is an useful organic reaction. This reaction is named after a British chemist Sir Robert Robinson. The term ’annulation ’stands for ’building a ring ’. In this reaction‚ the formation of α‚ β-unsaturated cyclic ketones from methl vinyl ketones and aldehyde or ketones takes place. Actually this reaction is a combination of two reactions. One is ’Michael Addition ’ and the other is ’Aldol Condensation ’. Robinson Annulation Mechanism In the first step

Wittig became an emeritus professor in 1967‚ where he remained until the end of his notable career (1). In 1967‚ he won the Otto Hahn Prize‚ and in 1979‚ he and Herbert C. Brown were jointly awarded the Nobel Prize for their development of the use of boron and phosphorus-containing compounds for important reagents in organic synthesis (1). The foundation of the Wittig reaction is not complex

APPLICATIONS OF ORGANIC COMPOUNDS IN LASER TECHNOLOGY WHAT IS AN ORGANIC COMPOUND? An organic compound is any member of a large class of gaseous‚ liquid‚ or solid chemical compounds whose molecules contain carbon. Organic chemistry is the science concerned with all aspects of organic compounds. Organic synthesis is the methodology of their preparation. APPLICATIONS OF ORGANIC COMPOUNDS clothing of cotton‚ wool‚ silk‚ and synthetic fibres; common fuels‚ such as wood‚ coal‚ petroleum‚ and natural

German organic chemist Hans Fischer (1881-1945) was awarded the Nobel Prize for chemistry in 1930 for his researches into the constitution of hemin and chlorophyll and especially for his synthesis of hemin. Hans Fischer‚ the son of Dr. Eugen Fischer‚ a manufacturer of chemicals‚ was born at Höchst am Main‚ on July 27‚ 1881. He entered the University of Lausanne in 1899‚ read chemistry and medicine‚ and subsequently transferred to the University of Marburg‚ where he graduated in chemistry in 1904
