IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

It’s your turn to host a small dinner party‚ and after going to your friends’ houses the last few times‚ you (and probably they too) have grown tired of the same food items on the menu: burgers‚ brats‚ and the occasional delivery pizza. You want to do something different and why not? If you are stumped on ideas‚ shake it up and try cooking authentic Mexican food. Mole is one of the most traditional dishes from our neighbors to the south and is a delicious place to start when deciding between Mexican

purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will then generate hydrobromic acid‚ an important product in the reaction mixture

Process Description Acetaldehyde is produced via dehydrogenation of Ethanol. The reaction is as below: CH3CH2OH CH3CHO + H2 ‚ ΔH = +82.5 kJ/mol Besides the main reaction producing Acetaldehyde‚ there are three side reactions present in the reactor‚ as shown below: 2 CH3CH2OH CH3COOC2H5 + H2 2 CH3CH2OH CH3(CH2)3OH + H2O CH3CH2OH + H2O CH3COOH + H2O The feed of 90% Ethanol is kept in a storage tank with an air vent. Tank blanketing is used in the storage tank with Nitrogen gas. This

used in this experiment) to yield the resultant alkyl halides and water. The insolubility of the alkyl halide in water allows the separation of it from the aqueous layer using a separatory funnel. The alkyl halide‚ then‚ were purified by a simple distillation apparatus using boiling point differences between the pure tert-butyl chloride and not. In this experiment‚ tert-butyl chloride is synthesized from tert-butyl alcohol. Introduction Alkyl Halides (also known as halogenoalkanes or haloalkanes)
