Let's assume you have a mixture of equal parts benzoic acid, sand and toluene that are intimately mixed together (the crude material is a mixture of solid and liquid). Propose a procedure to separate these three components using any of the chemicals commonly available (you've used all of the "common" chemicals in the lab by now) in the organic chemistry teaching laboratories and observing the typical limitations with the instruments and techniques (such as not being able to distill or...

Is this correct????
A 537 mg of a mixture of fluorene and benzoic acid was weighed out and subjected to an extraction and recrystallization. After this purification was completed the product crystals were dried and analyzed. The purification procedure produced 201 mg of fluorene and 242 mg of benzoic acid. Calculate the percent composition of this mixture.

A 577 mg of a mixture of fluorene and benzoic acid was weighed out and subjected to an extraction and recrystallization. After this purification was completed the product crystals were dried and analyzed. The purification procedure produced 247 mg of fluorene and 167 mg of benzoic acid. Calculate the percent composition of this mixture. Fluorene Benzoic Acid Number Number 0 0

A sample of benzoic acid, which should be pure white, was found to have a grayish color after recrystallization. The melting point was correct, and the melting point range was small. Explain why the melting point was still correct and occurred over a narrow range in spite of the grayish tint.

From You have a mixture of benzoic acid, hexamethylenediamine, and 1-octanol dissolved in diethyl ether. You wish (for some reason) to separate these compounds and have pure samples of each. Devise a liquid-liquid extraction protocol that would allow you to do this. (up to 20 points) Your answer should be clear and concise. Ambiguous answers or those that are difficult to read will NOT receive points. Search entries or author Unread Subscribe Reply

1. Can benzoic acid be recrystallized using Dichloromethane as a solvent instead of Water. Justify your answer. 2. Benzoic acid purified using recrystallization melted at 10 oC less than its actual M.P. Is the sample pure? List possible errors that could have happened during the recrystallization. 3. Where in the IR spectrum of benzoic acid would you expect to find the C=O and C=C bond?
