Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol

Learning Activity 1 Preparation of Acetanilide Abstract Recrystallization is a common method of purifying organic substances through the difference in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution‚ molecules of other compounds

1. Citric Acid * Citric acid is a weak organic acid with the molecular formula C6H8O7‚ which means a molecule of the acid contains six carbon atoms‚ eight hydrogen atoms‚ and seven oxygen atoms. When it is dissolved in water‚ it partially ionizes to yield three H+ ions (hydrogen atoms which are missing their electron) and a C6H5O7(3-) ion (the 3- means that it has three extra electrons.) The resulting solution is called an "electrolyte." Chemical Reaction When two dissimilar metals are put

Acetanilide Acetic acid Purpose: Acetanilide is a useful precursor to many pharmaceuticals such as acetaminophen and penicillin. Experimental Procedure. (Estimated time: 1.5 h.) Unless otherwise noted‚ all manipulations should be done in the chemical fume hood. Place 100 µL of aniline into a tared 10 X 75-mm test tube (standing in a small beaker or Erlenmeyer flask). Now add 0.5-mL of distilled water; with swirling‚ followed by 3 drops of concentrated hydrochloric acid. Add 10 mg of powdered
