Trimyristin Lab Report

Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction, solubility, crystallization and vacuum filtration. The experiment was carried out two times, both of which were successful.

Add the powder into a 100mL volumetric flask by using the folded side of the weighing paper. Gently slide the solid into the flask. Use distilled water to rinse the weighing paper into the flask. Fill the flask to the mark with distilled water. Then cap the flask with parafilm and mix thoroughly. This solution is now known as Master Solution. After rinsing the pipet three times with a small amount of the master solution, pipet exactly 10.00 mL of the master solution into a clean dry 250 mL Erlenmeyer flask. One should then repeat step 6 so that one should have three flasks with 10mL of the master solution in each. Then rinse the pipet three times with distilled water. Following that, rinse the pipet three times with a small amount of hydrochloric acid. Pipet exactly 10.00 mL of hydrochloric acid into each of the three flasks and swirl the flasks to make sure the solutions are mixed all the way. The solution should now be a yellowish precipitate. For part three, one should first rinse the buret three times with distilled water, then rinse the buret three times with a small amound of sodium hydroxide. Fill the buret with about 40mL of the sodium hydroxide solution and put the buret in a secure buret

*Peanut oil has a higher smoke point and has less of a chance of burning during the experiment.

The two peaks next to each other, 2360.23 cm-1 and 2341.78 cm-1, most likely indicated a nitrile or alkyl stretch. These peaks disappeared in the spectrum for the crystallized 3-nitrochalcone, though. The peaks were most likely as the result of an incomplete reaction or a reaction that did not go to completion. The product probably did not completely tautomerize, showing an alkyl or nitrile group. The crude product was also not completely dried, as indicated from the presence of an -OH group at the 3383.38 cm-1 peak. Figure 2 depicts the infrared spectrum of the crystallized product. The two peaks, signifying the nitrile or alkyl stretch, were still on the spectrum, but smaller. However, a peak at 3380.36 cm-1 indicates that an OH stretch is still present in the crystallized product. This verifies that the product was not pure; that –OH group was likely from methanol, the solvent used to purify the crude product. In order to remove the methanol/OH group, the crystallized product was left to dry in an oven for several minutes to spur dehydration. After that, another IR spectrum was taken for the dried product (Figure 3). In this spectrum, there was no alcohol peak, which indicates that the product became pure; the compound lost the hydroxyl group and no methanol was found in the pure product. As a result, Figure 3 is the desired

In the article Caution Candles by Science World, it states that, “When Massoudi tested paraffin candles in a special chamber, he found they emitted chemicals like toluene and benzene. Toluene can affect the nervous system, and benzene has been linked to cancer.” This quote tells you about how candles aren’t very romantic when you wake up with cancer after having your nerves being tampered with, or just being an idiot and touching the flame. A third reason why having a knowledge of chemistry is important in everyday life is knowing what chemicals do such as methane gas and where they come from.

However, there was strong odor from cinnamon oil and the effects of this oil from previous research leading to the conclusion that cinnamon oil provides that best protection to the wafers.

Injuries can still result from clothing that is flame resistant. The material is made to extinguish itself, but the material still becomes hot and melts which can burn the skin. The chemicals used in making material flame resistant can be harmful to humans. Some of the chemicals can cause impaired fetal brain development, reproductive problems, and cancer. Polybrominated Diphenyl a chemical used in flame resistant material was found to release gases during fires that would suffocate victims. Industries switched to an alternative chemical Chlorinated Tris, but some people still feel the risk of wearing flame resistant material is more detrimental than the risk of fire, and take measures to try and wash out the

This experiment can be used for many years to come. The experiment can be altered to test different kinds of flame resistant material. The tests can also include different fuel sources that might impact the flame resistance of material. The knowledge gained can be used to test and improve flame resistant material to make it more effective and less susceptible to decreased

Acetone is a volatile substance produced during ketone production which produces a fruity-scent and acts as a breath marker.

Initially, wavelength of the spectrometer was set to 425 nm. In preparing the potato extract along with the substrate (catechol) for the initial experiment, were placed in an ice bucket to maintain a low temperature in. Four beakers, four cuvettes along with four test tubes, which were kept in a rack, were positioned on the counter. Gloves were then obtain for safety as, four pH solution consisting of different levels, namely pH 3, 7, 9 and 11 as the controls, were

Paraffin wax (or simply "paraffin", but see alternative name for kerosene, above) is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 47 °C and 64 °C ( 117°F to 147°F), and having a density of around 0.9 g/cm. It is insoluble in water, but soluble in ether, benzene, and certain esters. Paraffin is unaffected by most common chemical reagents, but burns readily.
