Purification of Water Domestic: Distillation - In the process of distillation water is heated and evaporation takes place‚ whereby water changes back to water when cooled; this process is called condensation. The condensed water is the purest form of water‚ free from microbes‚ and impurities. Boiling - Boiling is the best and simplest method to purify water. After straining the water twice through clean muslin cloth‚ it is boiled for ten minutes lo kill the microbes present in it and also remove

Assignment Purification of a Mixture INTRODUCTION Mixtures obtained from the biosphere‚ lithosphere‚ hydrosphere or atmosphere can be industrially separated into their constituents. Petrol for example is obtained from crude oil found in the lithosphere. RESEARCH SKILLS When researching this assignment you will access a variety of secondary resources including web sites and textbooks. Please include a detailed bibliography You should also consider both the validity and reliability of your

OIL PURIFICATION A SCIENCE INVESTIGATORY PROJECT CHAPTER I Background of the Study INTRODUCTION Oil used in cooking foods is commonly derived from vegetables. Cooking oil is commonly used for frying and oil used for frying is usually thrown away. The recycling of cooking oil also provides a form of revenue for restaurants‚ which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being disposed

Isolation of Eugenol from Cloves Abstract The experiment conducted‚ isolation of eugenol from cloves‚ is the extraction of the essential oil. To perform this experiment cloves and water were mixed together and heated by a heating mantle in a round-bottom flask. A direct stem distillation took place‚ and the oil product was out aside for a week. After one week‚ the isolation of the eugenol actually takes place. Next the thin-layer chromatographic analysis takes place‚ but the experiment

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

Purification of Infliximab[3] begins at Stage 1 with the filtration of the harvest material using a spin filter. The harvest is then clarified and undergoes 3 main chromatographic steps. Firstly‚ at Stage 2‚ the direct protein capture by Protein A affinity chromatography helps to remove a large majority of the impurities whicn include viruses and media components. At Stage 3‚ prior to cation exchange chromatography‚ the purified material in the eluted stream is then subjected to freezing‚ thawing

mummion assignment Task 1 – purification Aim We were given a sample of mummion in the form of dried mud from a lake; the aim of the practical was to purify the sample and separate it from the insoluble impurities into the form of mummion salt. Context A long time ago mummion was used to preserve the bodies of ‘mummies’ in ancient Egypt‚ mummion along with other naturally occurring preservatives was used to treat the organs before the bodies were wrapped. This purification practical happens very often

Experiment 4: Isolation of Essential Oils from Eugenol Background: Anyone who has walked through a forest or who enjoys the variety of fragrances that flowers have to offer knows that many plants and trees have their own distinctively pleasant odors. These odors are due to the volatile essential oils‚ many of which have been prized commodities since ancient times. If a list of commercially important essential oils was compiled the list would exceed 200 essential oils. Thyme‚ garlic‚ peppermint

Introduction ESTERS are compounds derived from the reaction of a organic acid with an alcohol. Acid + Phenol/alcohol --> ester + water R--C=O + R’--OH ----> R--C=O + H2O | | C-OH C-O-R’ Esters are the compounds that give fruits their characteristic flavours and odours. ie. methyl salycilate is "Oil of Wintergreen". http://www.petrik.com/PUBLIC/library/misc/glossary_of_org_chem.htm#ESTERS Aim To synthesise the ester 3-methylbutyl ethanoate( isopentyl acetate) and to identify the product
