Hydrocinnamic acid underwent bromination using N-bromosuccinimide and AIBN. As one lab partner set up the reflux apparatus‚ the other measured the chemicals used in the lab experiment. 2.10 g of hydrocinnamic acid was used. It was observed as white and had a slight cinnamon smell. The amount of NBS was 2.49g and was measured in the fume hood. AIBN was measured at .030 g. 10 mL of acetic acid was also obtained. The reflux apparatus consisted of a 25 mL flask with a stir bar in a water bath. The chemicals

RUNNING HEAD: Synthesis of Banana Oil Abstract A reflux apparatus was assembled with a water-cooled condenser and a drying tube. Isopentyl alcohol‚ glacial acid sulfuric acid is added to a 25 milliliter round bottom flask and attached to the reflux apparatus. The mixture was boiled‚ the extracted first using water followed by aqueous sodium bicarbonate. The mixture was dried using anhydrous granular sodium sulfate. After dried‚ the sample was placed in a distillation apparatus and heated. This

Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ‚K3 [Fe (C2O4)3].3H2O. Introduction: Ferrous ammonium sulfate‚ Fe(NH4)2(SO4)2.6H2O is dissolved in a slightly acid solution‚ excess oxalic acid‚ H2C2O4‚ is added and the following reaction takes place: Fe(NH4)2(SO4)2.6H2O + H2C3O4

and fever. Aspirin were made using a combination of salicylic acid and acetic anhydride.The goal of this experiment was to determined the purity of aspirin using different methods. These methods included‚ reacting salicylic acid with FeCl3‚ finding its melting points‚ and by doing Thin-layer chromatography. When you reacted salicylic acid with FeCl3‚ changes in color will occur. Pure Aspirin has a melting point around 135°C and a pure salicylic acid has 158 °C. TLC is used to separate compounds based

Abstract Oxidation was found for primary alcohol. When 6 drops of potassium dichromate and 1 drop of concentrated sulfuric acid were added to 1-pentanol‚ the color of 1-pentaol turned into dark green. In second experiment‚ precipitation was found when 6 drops of 2‚4-dinitrophenylhydrazine were added to both 5 drops of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments

Title: Esterification Objective: To synthesis acetylsalicylic acid by esterification. Introduction: A pleasant‚ often fruity‚ odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples‚ the odor of n-propyl acetate is reminiscent of pears and isopentyl acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An esterification

technique used in this experiment is recrystallization. Recrystallization is an often-used method for purifying solids. Recrystallization works by taking advantage of the different solubility properties of compounds‚ and allows impurities to be removed from crude solids. Performing a recrystallization is usually a straightforward task. First‚ you add a small amount of solvent to the impure compound in a flask‚ and heat the contents until all the material has dissolved. Then‚ you cool the solution‚ allowing

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)
