Isolation of Eugenol from Cloves by Steam Distillation and its Identification by Infrared Spectroscopy Eim A. Chemist CHEM 303 June 16‚ 2005 INTRODUCTION “Essential oils” are the volatile components associated with the aromas of many plants.1 In this experiment‚ the essential oil eugenol (the main component of oil of cloves) will be isolated from ground cloves using the technique of steam distillation‚ which is often used to isolate liquid natural products from plants.2 The principle

2.2.1.6 Inductively Coupled Plasma-Atomic Emission Spectroscopy Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) is one of several techniques available in analytical atomic spectroscopy. ICP-AES utilizes plasma as the atomization and excitation source. Plasma is an electrically neutral‚ highly ionized gas that consists of ions‚ electrons‚ and atoms. Most analytical plasmas operate with pure argon or helium‚ which makes combustion impossible. Plasmas are characterized by their temperature

Organic vs. Inorganic Le’Trice Crawford CRJ311: Forensics Christopher Mancuso May 18 ‚ 2012 The world that we live in is made up of organic and inorganic materials. The thing is known which is when you are confronted with a list of objects. This is the reason in this paper I intend to show the difference between organic and inorganic organisms. The definition of organic which means‚ of or pertaining to an organ; or the organs of an animal

School of Chemistry @ Pietermaritzburg University of KwaZulu Natal Chemistry 310 Substitution reaction of Molybdenum Hexacarbonyl: the use of infrared spectroscopy as a structural tool in metal carbonyl chemistry. Abstract The synthesis of isomer A and B of [Mo(CO)4(PPh3)2] were prepared from molybdenum hexacarbonyl‚ sodium borohydride and triphenylphosphine with a % yield of 79% and 8.5% respectively. Two isomer was identified using IR spectra and from isomer A four C≡O stretching

fractional distillation. Once the fraction has been collected it must then be dried. The dried distillate is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double bond present. To assure the results were correct the chemical tests were done. The Bromine test was found

Between the symptoms‚ melting point‚ and results of the infrared spectroscopy we were able to identify what analgesic Jasper ingested. Results: After receiving all of the information and comparing the results of the symptoms‚ melting point‚ and infrared spectroscopy we concluded that they analgesic he was given was ibuprofen

Title: - Infrared Spectroscopy‚ Boiling point and Melting point. Introduction: - Infrared spectroscopy has also made a break though in medicine. It used to evaluate the kidney stone diseases thus broadening the use of IR in different ways. The purpose of this lab experiment is to identify the unknown solutions using the Infrared Spectroscopy (IR)‚ boiling point‚ and melting point (1). The IR helps to determine the compounds such as a functional group. In order to analyze the compound‚ IR and melting
