ynthesize my own aspirin Analyse the purity of my aspirin samples (aspirin and recrystallized aspirin) compared to commercial aspirin by use of analysing melting points, TLC plates and colorimetry tests Investigate how pH effects the rate of hydrolysis of aspirin Background theory Making my own sample of Salicylic acid (to then be converted into Aspirin)…

The different component in the mixture pass through he column at differentiates due to differences in their partition behavior between the mobile phase and the stationary phase. The mobile phase must be degassed to eliminate the formation of air bubbles. Types: Partition chromatography Adsorption, or liquid-solid Liquid chromatography Ion exchange chromatography Size exclusion, or gel,…

Abstract: A mixture of Fluorene (1) and Fluorenone (2) was separated by column chromatography. Chemical Equation: Fluorene (1)Fluorenone (2) Mp 114? Cmp 83? C MW 166. 22MW 180. 21 Introduction: Column chromatography was invented by Tswett in 1906 so that his study of the chemistry of chlorophyll could be facilitated. Tswett made significant advances in…

Introduction In this lab we will be using the Friedel Crafts procedure of acetylation of ferrocene. Ferrocene is an atom of Fe bounded by two aromatic rings. We will utilize some reagents that will do the ferrocene to add either one ethanoyl group group to an aromatic ring or add two acetyl groups to each…
