Extraction and Saponification of Trimyristin from Nutmeg by Katherine Wu on Prezi

extraction of trimyristin from nutmeg

The crude solid was purified using a recrystallization technique. The experiment was performed successfully for the most part, disregarding a few minor mistakes made in the procedure. Also, it is good to know that due to impurity the best way purify the product of trimyristin is by recrystallization through hot acetone. The organic solvents that were used in the experiment were diethyl ether, methylene chloride and ethyl acetate. The solution was warmed on the sand bath to dissolve, then cooled to room temperature over the course of 5 minutes. The health problems of an elderly, adult and children who are socially isolated are increasing.

That is a result of social isolation. The crystals were collected by vacuum filtration and were allowed to dry. Only twenty to twenty-five percent of trimyristin makes up the mass of nutmeg and it is formed from the glycerol and saturated carboxylic acid 2. It is a substituent of the triglyceride called trimyristin, which embodies 20-25% of the dried weight of ground nutmeg we will eventually use in this experiment. It was also proven that trimyristin is soluble in acetone, the substance we used for recrystallization. The change in culture sparked a change in cinema that appealed to a younger audience.

If the samples were pure we would have seen the first drop of trimyristin at 56°C and the last drop at 58°C. Many different relationships are part of social interaction such as family, neighbor, friends and work colleagues. Then, the liquid was transferred into the pressure filtration assembly. Due to the varying chemical properties of each of these compounds, it is easy to separate many of them using common organic chemistry techniques. Society is the connection between people live together in communicates for love, friend and support. It is advised to know that when ethyl acetate and water are mixed, the water will eventually separate into two distinct phases. Santiago experiences isolation when he is at sea, and has lots of time to think about himself and reflect on his life and decisions.

This was warmed briefly and let settle, then pipetted to the centrifuge tube again. During the same time, the flask was warmed on a sand bath in order to dissolve the solid. Introduction The purpose of this lab is to isolate the pure organic compound from nutmeg. Trimyristin is extracted from a nutmeg seed using Tert-butyl methyl ether. However, some people lack of participation, activity and communication. Most of the other components of Nutmeg remain in the acetone as they are ether soluble. From trimyristin we were to use hydrolysis to break the molecule down further and get myristic acid.

This is a result of a loss of the samples during the partition process, reflux, as well as recrystallization. Procedure The sand bath was set to 30%, then set it to 20%. Instead of having a melting point at 54°C-55°C we got a melting point of 50°C-52°C which reflects the impurities previously stated. This was boiled for 10 minutes on the sand bath. This procedure also used to extract coconut oil which is also a component of trimyristin , palm kernel oil, etc. The solid was settled again in the tube. These sources were from fungi, plants, bacteria, animals, etc.

We used the melting points to determine if we isolated a pure sample from both trimyristin and myristic acid. This is slightly lower than expected. The filtrate was then transferred into a clean, dry, and tarred Erlenmeyer flask. The Mel-Temp was turned off, as well as the air and vacuum. This could have been from not waiting long enough for crystals to form, or a small amount of Trimyristin stayed dissolved in the solution.

In most situations no, you are oblivious to what other people are doing around you because you are so involved in your social media connections. Do you agree or disagree? Then it was allowed to slowly cool to room temperature and placed into an ice bath for 10 minutes. In a recrystallization procedure, the crude solid is dissolved by heating it in a minimal amount of a solvent recrystallization solvent. The melting point of myristic acid is then found. Theoretical Yield, Percent Yield and Discussion: The weight of the product is determined to be 0. Although nutmeg is one of those natural sources that trimyristin is easily extracted from it does take some time to achieve in lab.

Like most extractions, isolating trimyristin is complex considering a variety of products are extracted in the solvent. The relative abundance of trimyristin in nutmeg makes it a potentially necessary substance to partition. This lab set out to do exactly what it was supposed to by taking us step by step into extracting something from a natural source. For instance, it took a long time for the solvent to evaporate because the hot plate was set at too low of a temperature. Ground nutmeg seeds are extracted with methyl ether and the resulting solid recrystallized from acetone and to yield pure trimyristin.

This was expected to be much higher than the average 20-25% recovery from nutmeg, as it still contained many impurities. The remainder should be left to air dry for 5 minutes and the weight was recorded to be 24. The solution was allowed to boil gently for 30 minutes until it was removed and set aside to cool. . A minimal amount of methylene chloride was then used to wash any excess residue out of the round bottom flask and into the filter. The solution was refluxed on the sand bath for 45 minutes.

We can state however, that the impurity was not by a lot since we were fairly close to the literature value. The Trimyristin was recrystallized a second time, cooled yet again to room temperature and then placed in an ice bath. Since, we did not see the melting point of trimyristin at 56°C but at 46°C we know that it was not a pure sample and therefore, had impurities which explain the low melting points with myristic acid. After the myristic acid is collected we will be using its melting point to determine whether we successfully isolated pure form of the crystal. This eventually leads to him making up voices of scorn and pity. Hydrolysis and acidification make glycerol and myristic acid. Everyone experiences isolation at some point in their lives.
