halogenation reaction. If the bromine reacted with the alkene the bromine would discolor from orange and turn clear. Experiment Part A) Solubility of Alkanes: 1 mL of nine solvents (water‚ methanol‚ n-butanol‚ ethylene‚ glycol‚ acetone‚ hexane‚ toluene‚ ethyl acetate‚ and dichloromethane.) was added to nine sample vials. Each vial then had 0.5 mL of the alkane decalin added to each one. The mixtures were stirred to determine if the materials dissolved. If the material was insoluble it was heated

The physical state and color were noted by simple physical observation. Nitration Testing was conducted for preliminary

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

2014-2015 Distillation of Gin Solis‚ Ferguie B.*‚ Sto. Domingo‚ Hannah Beatrix‚ Sy‚ Kurt A. 2 BS Chemistry‚ College of Science‚ University of Sto. Thomas España‚ Manila‚ Philippines‚ 1008 Abstract Distillation is the separation of a mixture into its component due to the difference in boiling point. In this experiment the group made use of Gin manufactured by Ginebra San Miguel as a test sample for two different techniques of distillation. The techniques used were simple distillation and fractional distillation

temperatures without a catalyst‚ or lower temperatures and pressures in the presence of a catalyst. The source of the large hydrocarbon molecules is often the naphtha fraction or the gas oil fraction from the fractional distillation of crude oil (petroleum). These fractions are obtained from the distillation process as liquids‚ but are re-vaporised before cracking. There isn’t any single unique reaction happening in the cracker. The hydrocarbon molecules are broken up in a fairly random way to produce

Experiment 16: Fractional Distillation of a Mixture CHM2210L Kelley Paul May 26‚ 2014 Tuesday Session: 50432 Abstract A distillation experiment was performed in attempt to separate two miscible fluids.This experiment used fractional distillation to separate ethanol from the azeotropic mixture of ethanol and water. The initial composition of the solution did not matter because the goal of the experiment was to distill the ethanol-water solution and obtain 95% ethanol in the distilled fraction
