Dehydration of Alcohols Abstract The dehydration of cyclohexanol to cyclohexene can be done through fractional distillation. Once the fraction has been collected it must then be dried. The dried distillate is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double

Samuel Beckett described his Waiting for Godot as a tragicomedy. To what extent is this is an accurate description? Would you say there is more tragedy than comedy or a mixture of both? Through the use of many linguistic‚ structural and comic features‚ Samuel Beckett’s Waiting For Godot successfully places a wayfaring line between the two genres of tragedy and comedy. With the opening showing the two main characters Vladimir (Didi) and Estragon (Gogo) in a barren setting with useless props such as

Living organisms are nature’s laboratory where many chemical transformations are taking place independently‚ simultaneously and continuously. Hence most organic sample are mixtures of compounds. However‚ the need for identification of these numerous compounds of carbon had led to their division into groups/family based on some of their common features. One of the major questions requiring on answer in organic Chemistry

Examples of industrial chemical processes include distillation‚ smelting‚ disinfection‚ and Pyro processing. Even today‚ scientists in our industry continue to find‚ develop‚ and create new products with the experimentation of the chemical processes. Without these chemical processes‚ we would probably not be able to live the way we do today. Today‚ distillation is one of the most widely used methods worldwide. Distillation is the separation of mixtures and the removal of all the impurities based on

The presence of impure reaction-there may be some impurities in the reaction mixture‚ in this way‚ the yield will be non-stoichiometric.

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
