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

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

EXPERIMENT A: CIS-TRANS CONVERSION OF BUTENEDIOIC ACID PRE-LAB ASSIGNMENT 1. Maleic acid is the cis version and fumaric acis is the trans version of butenedioic acid. 2. 3. See attached paper. 4. Maleic anhydride is the compound that crystalizes in part A in the experiment. 5. HCl acts as a catalyst to break one of the carbonyl group in the maleic acid which rotates the structure to form a trans structure of the butonal acid which is the fumaric acid. And it does so by donating

Experiment 1 :Alkanes&Alkenes:Combustion and action of sulphuric acid. Introduction In the study of organic chemistry‚ the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. They can be gases as‚ propane‚ they can be liquids‚ for example‚ benzene‚ or they can be low-melting solids and waxes‚ for example‚ polystyrene. There are four classifications of hydrocarbons; saturated hydrocarbons or alkanes‚ unsaturated hydrocarbons or alkenes and alkynes‚ cycloalkanes‚ and

The Purity and Purification of Solids Recrystallization ABSTRACT In this experiment‚ impure adipic acid is purified though recrystallization. The impure adipic acid is dissolved in a solvent. After cooling it is ran through a vacuum filter to separate any moisture. The dry crystals are then weight for percent yield and the melting point range is taken to test the purity. There were two different trials ran in this experiment. The difference between the two was the addition of charcoal in

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 55: A Separation and Purification Scheme The final lab report/procedure write-up will consist of the following: Report guide: 1. List the names‚ structures‚ and amounts of each compound in your mixture. 2. Draw a flow chart (like pg 687 in PLKE) showing how you separated and isolated your two compounds. Be sure to include the structures of the compounds at each step. 3. Write a procedure. This should include exactly how you performed your separation. It should have enough
