RECRYSTALLISATION PRESNTED BY Mariam SeiduPriscilla TweneboahEvans Appiah-Kubi 3796509 Yaw Adu PokuEric Adjei 3809009 INTRODUCTION Recrystallization is a method of purifying a solid. There are two types of impurities: those more soluble in a given solvent than the main component and those less soluble. (If there are any impurities that have the same solubility as the main component‚ then a different solvent needs to be chosen.) When organic

Lab #4 May 26‚ 2015 Diels Alder Reaction Introduction: Diels Alder Reaction is the reaction of a diene with a species capable of reacting with the diene‚ the dienophile. A diene is a hydrocarbon that contains two carbon double bonds‚ while a dienophile is an electron-deficient alkene. The Diels-Alder is also called a [4+2] cycloaddition because a ring is formed by the interaction of four pi electrons of the alkene with two pi electrons of the alkene or alkyne. The product of the Diels-Alder

their corresponding salts‚ they can be separated from the rest of the solution by trapping them in an aqueous layer. A solution of an acid component‚ a basic component‚ and a neutral component that has been dissolved in an organic solvent‚ such as diethyl ether‚ can be separated using this type of extraction. To extract the acidic component aqueous from this solution aqueous NaOH must be added to convert the acid to its corresponding sodium carboxylate. The base and the neutral components will not react
