of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and cost-effective technique which remains a strong link to the vast pre-instrumental chemistry literature‚ so the technique is still used for measuring purity of organic and pharmaceutical compounds. For that reason‚ determination of the

but also an advisable and accepted mode of treating diseases even in developed countries. The subject of phytochemistry or plant chemistry has been developed in recent years as a distinct discipline‚ somewhere in between plant biochemistry and natural product organic chemistry and is closely related to both. It is concerned and linked with the enormous variety of organic substances that are synthesized‚ elaborated and accumulated by wide variety of plants and deals with the chemical structures and

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

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.

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
