TWO-BASE EXTRACTION OF BENZOIC ACID‚ 2-NAPHTHOL‚ AND NAPHTHALENE FROM UNKNOWN SAMPLE # 131 Douglas G. Balmer (T.A. Mike Hall) Dr. Dailey Submitted 11 July 2007 Introduction: The purpose of this experiment was to separate a sample of benzoic acid‚ 2- naphthol‚ and naphthalene of unknown proportions using a two-base extraction method. The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases’ conjugate acids has a different

Procedure: 1. Carefully pour the vinegar into the bottle. 2. Loosen up the balloon by stretching it a few times and then use the funnel to fill

Maleic anhydride underwent the Dials-Alder reaction with distilled cyclopentadiene as the dienophile. The reaction was a cycloaddition which produced cis-Norbornene-5‚6-endo-dicarboxylic Anhydride surface. (1) Product one had a mass of 9.351 grams and product two had a mass of 9.572 grams. The theoretical yield was found to be 10.047 grams‚ which makes the percent yield to be 93.07%. Melting Points were found to confirm the purity of the product. Product one had a melting point of 163.7-164

PbNO3 and 1.44g of KI were acquired. 2) Assemble filtration system. The filter paper was to be folded and inserted into the funnel. Seal the filter paper to the funnel by using water. The funnel was set into the flask. 3) The substances were dissolved in 25 ml of water in beakers. 4) The solutions were thoroughly mixed together and then poured through the funnel. This separated the precipitate from the filter. 5) Separate the precipitate from the filter and place into beaker. 6)

LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized
