    presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was performed using two acid catalysts‚ 85% phosphoric acid and sulfuric acid. Tests for unsaturation were performed adding drops of bromine in tetrachloride and potassium permanganate to four test tubes‚ two containing 5 drops of cyclohexanol(control)

    COVENANT UNIVERSITY FACULTY OF SCIENCE AND TECHNOLOGY DEPARTMENT OF CHEMISTRY COURSE TITLE: General Organic Chemistry COURSE CODE: CHM 121 ‚ UNIT: 2.0 . INTRODUCTORY AND IMPORTANCE OF ORGANIC CHEMISTRY Organic chemistry is the study of the compounds of carbon. Carbon compounds are far more numerous than those of other elements because carbon are able to bond together to form a wide range of chains and rings. The subject is named organic chemistry because living organisms are composed

    utilized by removing water from the products. As a result‚ the reaction as a whole shifts the left producing more isoamyl acetate to try and balance the reaction once again. Once the product was collected‚ it was purified through means of fractional distillation. Finally to characterize the product‚ and assess its purity‚ IR and NMR spectroscopy were taken.

    pyrolysis of the cyclic secondary alcohol with an acid catalyst at a moderate temperature or by distillation over alumina or silica gel. We will be performing catalysis by phosphoric acid. The mixture of cyclohexanol with phosphoric acid is heated in a flask equipped with a fractionating column‚ forming water. Further heating promotes the distillation of water and cyclohexene by the principle of stem distillation. A chaser solvent is added to recover of the reaction product that may get lost in the fractionating

    Introduction: Cyclohexanol is mainly used in the production of caprolactam and adipic acid that is a raw material of nylon 6 (Zhang‚ et al‚ 2002). Cyclohexanol can be produce through several methods‚ which include the oxidation of cyclohexane‚ the hydration of cyclohexene‚ or the hydrogenation of phenol (Zhang‚ et al‚ 2002). Problem with oxidation of cyclohexene is poor selectivity‚ extremely large recycles and explosion hazards. (Suresh‚ Sridhar‚ Potter‚ 1988). The purpose of this experiment was

    Application of linear algebraic equation for chemical engineering problem The chemical engineering system models often outcome of set of linear algebraic equations. These problems may range in complexity from a set of two simultaneous linear algebraic equations to a set involving 1000 or even 10‚000 equations. The solution of a set two or three linear algebraic equations can be obtained easily by the algebraic elimination of variables or by the application of cramer’s rule. However for systems involving

    specific time and temperature. They are dried until their reached constant mass. The percentage of moisture content can be determined by performing some simple calculations. Another method is‚ distillation method (dean & stark). A known weight of food is placed in a flask with an organic solvent such as xylene or toluene. The organic solvent must be insoluble with water‚ have a higher boiling point than water and less dense than water. (Faichney‚ G.J. and G.A.

    Ethanol can be created using two methods: acid catalysed hydration of ethylene and through fermentation of sucrose. The purpose of this experiment was to use fermentation to produce ethanol from commercial sucrose (store-bought sugar)‚ using fractional distillation of the fermented solution. The percent ethanol in the fermented solution was then calculated. Mechanism: Results: Mass of conical vial 10.36 g Mass of conical vial with distillate 11.17 g Mass of distillate (mass of vial-mass of vial with
