Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

Preparation Of Triphenylmethanol Objectives 1. To study the preparation of triphenylmethanol using through Gridnard reaction 2. To study the operations of anhydrous reaction‚ water vapor distillation. Principles Alcohol is widely used in organic chemistry‚ not only as solute but also as intermediate to synthesize halide‚ alkene‚ ether‚ aldehyde and ketone etc. In laboratory‚ an important method of synthesizing alcohol is though the addition reaction of Gridnard reagent and carbonyl compound‚ whereas

halide from alcohol and a hydrogen halide. In order to do this‚ tert-butyl alcohol was mixed with HCl to form crude tert-butyl chloride. Solid NaHCO3 and CaCl2 were used to prevent possible hydrolysis of the product. It was then purified through distillation. Results confirm the successful production of 5.01 g (51.5% yield) of the alkyl halide‚ tert-butyl choride. ------------------------------------------------- INTRODUCTION The importance of alkyl halides is great as it can be used in making

Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined that the unknown solid’s identity

Irish monks brought the alembic and the secret of distillation from the Middle East‚ according to the history of Irish Distillers. The Irish name “uisce beatha” translates to “water of life” (Kennelly‚ 3). There are four types of Irish whiskey: single malt‚ single grain‚ “peated” malts‚ which are grains dried with Irish peat for a smoky taste‚ and blended‚ which contains a variation of malt and grain. The production of each is different by distillation process. Irish whiskey is also aged in oak casks

Chapter I INTRODUCTION A. Background of the Study Ethanol is a clean-burning‚ high-octane fuel and is made from a renewable resource made from American corn and different cellulosic materials. Ethanol has many uses. It can be used as a biofuel (which reduces greenhouse effect) and it can be used for making different materials like perfumes and explosives. It is also called ethyl alcohol. Ethanol can be produced by banana peelings but we don’t know which peeling

These functional groups are removed by using a basic solution as shown in (i) below1. The product formed with water is stable only due to resonance‚ but does

disposal. So‚ we are here with an idea of using that waste peelings to produce ethanol to help for its increasing demand in the present situation. Method: The production of Ethanol from Banana peels involves two phases. i)Fermentation ii)Distillation The peels of nendran variety of bananas are taken as they are rich in cellulose and are kept in hot oven at 338K and dried sample is taken and is dissolved in hot water for starch extraction through soxhlet apparatus. This solution is treated

When that is completed add 20 mL of water into the flask to perform a simple distillation to collect the distillate in a graduated cylinder‚ keep doing this until there is no more 2-Bromobutane collected.
