example of self-condensation. In this lab‚ we were performing a mixed condensation‚ so this side reaction would not be favorable. The second reaction would occur if there was excess acetone in the reaction‚ causing acetone to further react with the desired final product. The last side reaction is due to not enough acetone in the reaction‚ only able to add to one side of the carbonyl and ultimately in the wrong position. This is why it was important to pay special attention to the amounts of reactants

2: Also‚ since the recycled acetone will not be pure‚ the pretreatment using recycled acetone should be tested to see the feasibility of the proposal. Response: After evaporation‚ only acetone together with some water is recovered; the solids‚ catalyst (sulfuric acid)‚ and other stuff cannot be evaporated. Then 50 % v/v acetone-water solution can be made by adding the necessary water. In principle‚ as there are no more volatile components in the system‚ except acetone and water‚ we did not have

those natural sources that trimyristin is easily extracted from it does take some time to achieve in lab. Ground nutmeg seeds are extracted with methyl ether and the resulting solid recrystallized from acetone and to yield pure trimyristin. Most of the other components of Nutmeg remain in the acetone as they are ether soluble. The hydrolysis of trimyristin follows acidification and yields glycerol and myristic acid. After the myristic acid is collected we will be using its melting point to determine

The acetone was decanted into a separatory funnel without transferring any spinach leaves by using a powder funnel with a cotton plug. 4. An Erlenmeyer flask was used to press the spinach and 25 mL of acetone was added to the spinach leaves and mixed as before‚ repeated twice. 5. 25 mL of hexane

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

on 10 March‚ 2013 Introduction: This practical is meant to measure the rate of reaction of the hydrolysis of tertiary-butyl chloride –a colorless‚ liquid organic compound at room temperature that is sparingly soluble in water - in water/acetone and water/isopropanol mixtures. Since there are many influencing factors for the rate of reaction‚ all are kept constant but the intended variable: the solvents. If the reactant is more stabilized by interaction with solvent molecules than is the
