T-1 and place the filter paper in the funnel - flute the filter paper with diethyl ether - pour the contents of the RB flask in Part A into the new RB flask Part C: I let that stand to dry a few minutes, and recrystallized it with acetone. Take the necessary safety precautions and be patient and calm in order to avoid unfortunate accidents with chemicals and fire.
The remains were the yellow solid of crude trymyristin mentioned in the lab description. Occuring in many vegetable oils as well as myristic acid.
This often consists of partitioning products between aqueous and organic solvents or partitioning at a particular temperature.
Thus using a relatively nonpolar solvent, trimyristin can be easily extracted by the concept of "like dissolves like".
However, acetone is an organic solvent that can more easily dissolve trimyristin at a higher temperature than diethyl ether. I let it cool in the ice bath for 15 minutes before collecting the crystals via vacuum filtration.
In the fume hood, I measured 2mL of concentrated HCl drop wise, stirring it with a glass stirring rod. The crystals came out to be 0. Allow the filtrate to cool and recrystallize and allow the resultant trimyristin to stand so that it gets air-dried.
I put 2 mL of tert-butyl methyl ether into the round bottom flask, heated it again for about five minutes, and repeated the same procedure. Vacuum filter uses the thick vacuum tubes, not thin ones!
Some excess in residue were probably disregarded. The precipitation of myristic acid was brown and fumed a bit while I added the concentrated HCl. Trimyristin does not dissolve in water, a characteristics it shares with various other fatty acids and oily compounds However, it dissolves quite easily in chloroform, ethanol, benzene, ether and dicloromethane.
Fix the condenser to this nutmeg-diethyl ethanol mixture containing flask and secure it properly in the metal block. The subfield of organic chemistry that deals with isolating and studying chemicals found in nature is natural products chemistry.
Apart from nutmeg, trimyristin is also found in a lot of vegetable oils that have a high saturated fat content.Trimyristin from Nutmeg. This experiment illustrates the process of obtaining a pure organic compound from a natural source.
Normally, because extracts from natural sources contain complex mixtures of compounds, isolation of a single pure compound requires long.
Extraction of Trimyristin from Nutmeg Lab. 1. Why is acetone a good solvent to recrystallize the trymyristin? What are the disadvantages?
2. Assume that the amount of trimyristin in nutmeg %(1). The trimyristin was extracted by using the solvent, diethyl ether and heat to draw the organic oil out of the ground nutmeg. Once the oil was extracted, the trimyristin was crystallized from the oil by using acetone. In this lab you will isolate trimyristin from nutmeg by performing a simple solid- liquid extraction.
When you perform this extraction, you will get an impure product. Weigh the TRIMYRISTIN and DETERMINE its melting point. the reported is dergrees celsisu. USE PERCENT RECOVERY based on the original weight of NUTMEG USED.
The purpose of this lab is to extract trimyristin from nutmeg with the organic substance, diethyl ether, to evidently produce trimyristin with a small portion of myristicin (solid-liquid extraction).
Also, it is good to know that due to impurity the best way purify the product of trimyristin .Download
