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)

was pretty certain the magnet would be used to collect the iron filings. I also thought that some type of filtration would be used to separate the sand‚ and honestly didn’t have a clue as to how to separate the benzoic acid. I did presume that distillation would be used to separate the salt. The actual method of boiling and dissolving the salt and benzoic acid was very interesting; and I did not expect the sand to simply stay put when pouring out the other elements. B. I would expect there to be

Heather Myers iLab‚ Week #6 CRUDE OIL DISTILLATION Introduction The purpose of this lab is to distill crude oil and learn how the chemical properties influence the temperature. The distillation of a substance is based on the boiling points. When the crude oil is brought to a boil‚ at 275°C‚ the gasoline and kerosene are distilled‚ but the lubricant remains part of the crude oil. Procedure 1. From the Equipment menu‚ select Distillation Equipment and obtain a Round Bottom Flask (100 ml). 2. Select

Edward Cross Organic Chemistry December 10‚ 2012 Title Steam Distillation of Cloves and Extraction of Eugenol Authors Edward J. Cross* Summary The isolation of Eugenol from Cloves begins with whole cloves and then using a steam distillation apparatus to obtain the cloves oil substance. Then with the mixtures of water and dichloromethane to form two immiscible layers. The layers were dichloromethane substance and aqueous The entire substances that are separated into two individual

Isolation of Acetyleugenol (Clove Oil) from Cloves Purpose In this experiment‚ you will obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but

are more than 240 million bottles in 200 countries. This puts Bacardi as the world’s largest rum company. The story of the Bat begins in Santiago de Cuba‚ where the founder of Bacardi‚ Don Facundo Bacardi Massó began experimenting with the distillation of rum. In Order to supply his rums beyond his friends and family‚ he purchased a small tin roofed distillery for the price of 3‚500 pesos. After entering the distillery‚ his wife noticed a colony of fruit bats hanging from the rafters. Bats

Figure 1: Distillation apparatus Reflux is required if the reactants‚ catalyst or solvent is volatile and likely to escape. Distillation is preferred if the product is volatile‚ or if there is a danger of further reaction. Many reactions are very vigorous at the beginning and can react violently. Often
