Isolation of the Major Constituents of Clove Oil Organic Chemistry Laboratory II‚ 10 February 2011 Corey Cates Introduction and Objectives The purpose of this lab was to obtain a pure sample of clove oil from ground cloves using steam distillation‚ perform infrared spectroscopy on the sample‚ and analyze the IR to identify the major constituent in the clove oil. The first day the clove oil was removed from the ground cloves into an aqueous solution then removed from the water using DCM. The sample

INFRARED By Johnny B. English Sr. SFTY 355 - Industrial Hygiene and Toxicology Tim Deak May 29‚ 2013 Thermal radiation also known as infrared which is a form of light that can not be seen‚ we can only see visible light. Infrared gives us information that we would not be able to get from visible light. Because all object gives off some type of heat‚ yes‚ all objects even if the of cold or frozen. Cold or frozen objects only gives off a very small amount of heat‚ but this heat can be detected

Introduction Eugenol is a naturally occurring chemical that has medical applications such as its use as a natural dental anesthetic. It can be extracted from cloves by using the method of steam distillation. The extracted compound will then be separated from the water using methyl chloride‚ which will then be evaporated using a rotary evaporator leaving only the essential oil‚ Eugenol. IR spectroscopy will be used to determine the structure of the extracted compound. Results and Discussion Four

removal of hydrogen from the OH group. After separation and purification‚ an Infrared Spectrum will be run to determine the composition of the recovered material. Infrared Spectroscopy is a very powerful technique used in the determination of molecular structure and the identification of unknown organic materials. The infrared spectrum yields direct information about the presence or absence of key functional groups. "The region of the infrared spectrum which

Substitution Reactions of Molybdenum Hexacarbonyl and the Use of Infrared Spectroscopy as a Structural Tool 01-09-2011 Abstract A variety of metal carbonyl derivatives can be synthesized by substitution reactions. In this experiment two geometric [Mo(CO)4(PPh3)2] isomers A and B were synthesized and their molecular geometries were determined by means of infrared spectroscopy. Isomer A was synthesized first by reacting [Mo(CO)6] with sodium borohydride employed as a reducing agent and triphenylphosphine

Abstract In the following project we are discussing about distillation. The operation of the distillation is employed for the purification of liquids from non-volatile impurities. The liquid is heated to the vapor phase and then is collected and recondensed to give back the pure liquid .The non-volatile impurities are left behind in the flask. Here our main focus will be at the fractional distillation. It is the process in which we separate the different components of a mixture on the basis of the

PRACTICAL REPORT ON THE ISOLATION AND IDENTIFICATION OF CODEINE AND PARACETAMOLPRACTICAL REPORT ON THE ISOLATION AND IDENTIFICATION OF CODEINE AND PARACETAMOL AIM: To extract codeine and paracetamol from its tablet by solvent extraction and tentatively identify in comparison to standards using Thin Layer Chromatography. INTRODUCTION: Codeine or methyl morphine‚ an alkaloid‚ was first isolated in 1832 from raw opium. It concentration ranges from 0.2% to 0.8%. Mostly used for its analgesic‚

1 ABSTRACT Distillation is a process by which one liquid can be separated from another liquid‚ or a liquid from a nonvolatile solid. In this experiment‚ the distillations of cyclohexane and toluene mixture were carried out. The purpose of this experiment is to compare the efficiency of simple distillation versus fractional distillation for separation of a mixture of toluene and cyclohexane. The mixture was first separated using simple distillation. A simple distillation apparatus was set

Introduction Caffeine is a very common substance and is found in coffee‚ tea‚ soft drinks‚ chocolate‚ and "stay-awake" pills such as Vivarin. It can be synthesized or isolated from natural sources. Caffeine constitutes approximately 4% of tea and coffee leaves‚ and is also found in cola nuts and cacao beans. Caffeine is a member

Each of them has their own special use in everyday life. For example‚ to turn on a TV you need to use Radio waves‚ to heat your food you use Microwaves and X-rays are used to look into people’s bodies. Some waves‚ like Radio waves can be as big as a building or waves like Gamma rays can be as small as nuclei. Infrared light is in between the microwaves
