Acetone

Discussion In this experiment, the chemical reaction between acetone (CH3COCH3) and iodine (I2) to make CH3COCH2I, I-, and H+ was observed. Under normal circumstances, this reaction would occur very slowly. In order to speed up the process, hydrochloric acid (H+) was used as a catalyst. A catalyst is a substance that can speed up a reaction by lowering the activation energy of the reaction. It does this by changing the mechanism of the reaction and providing more energetically favorable…

Introduction Acetone (dimethyl ketone, 2-propane, CH3COCH3), formulation weight 58,079, isthe simplest and the most important of the ketones. It is a colourless, mobile, flammableliquid with a mildly pungent and somewhat aromatic odour. It is miscible in all proportionswith water and with organic solvents such as ether, methanol, ethyl alcohol, and esters.Acetone is used as a solvent for cellulose acetate and nitrocellulose, as a carrier for acetyleneand as a raw material for the chemical…

the mixture to the separatory funnel. -Make sure there was no leak. 5. Add acetone (15mL) to the separatory funnel and cap the funnel. Extracted the aqueous layer. 6. Allow the two phases to separate. Drain the acetone phase into a 50 mL Erlenmeyer flask. 7. Re-extract the aqueous layer in the separatory funnel with a new portion of acetone (10mL). Swirl the phases together as described in step 5. Combined the second acetone extract with the first in the 50 mL Erlenmeyer flask.…

The objective of today’s lab was to determine the reaction rate of iodine and determine the reaction order for H+ and acetone. In order to do this, we ran 7 reactions with HCl, I2, Water, and Acetone. Every Run had different amounts of one of the components. These reactions allowed us to calculate the reaction rates for each of the 7 trials by dividing the molarity of the I2 by the time the reaction took. Next we had to determine the reaction order which required us to put each reaction rate,…

Experiment 1 sought to separate a binary solution into two fractions and determine the identity of the components. This is accomplished through distillation which is the separation of a mixture of compounds. There are two types of distillation; simple and fractional. Simple distillation is used when separating liquids and solids or between liquids with boiling points that differ by more than 40-50°C. On the other hand, fractional distillation separates two volatile liquids in order to achieve…

Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…

rotary evaporator. Another solvent system, acetone, was then added to the resulting oil for recrystallization. This solvent system was chosen because its increased polarity due to the keytone contained within causes trimyristin to be soluble at higher temperatures, but no longer soluble when cooled down. By heating up mixture as acetone was added then cooled down in an ice bath, recrystallization was allowed to occur. After crystals formed the acetone was removed via vacuum filtration. Upon…

regular nail polish, but must be cured in a UV or LED lamp. Curing time for a UV lamp is about 2 minutes where curing with an LED lamp is about 30 seconds. One point for the LED lamp. Removing gel nail polish requires a 10 to 15 minute soak in acetone. Let’s get to the pros and cons. The pros. A manicure using gel polish last longer than one using regular nail polish. I’ve read different claims about how long gel polish lasts, but the consensus seems to be two weeks or longer. It…
