Trimyristin, also known as myristin or myristyl myristate, is a saturated fatty acid ester that is commonly used as a skin conditioning agent in cosmetics and personal care products. It is a white, waxy solid that has a high melting point and a relatively low boiling point.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure, and the liquid begins to boil and turn into a gas. The boiling point of a substance is influenced by several factors, including the molecular structure of the compound, the strength of the intermolecular forces between the molecules, and the presence of impurities or other substances that can affect the boiling point.
Trimyristin has a relatively low boiling point compared to other saturated fatty acid esters, such as stearyl stearate or cetyl palmitate. It has a boiling point of approximately 300-310°F (149-154°C), which is lower than the boiling point of water (212°F or 100°C). This lower boiling point makes trimyristin easier to vaporize and more suitable for use in products that require a low-temperature heating process.
In addition to its low boiling point, trimyristin has several other properties that make it useful in the cosmetics and personal care industry. It is an excellent emollient and skin conditioning agent, and it helps to improve the smoothness and softness of the skin. It is also resistant to rancidity and has a relatively long shelf life, which makes it a stable and reliable ingredient in a variety of personal care products.
Overall, trimyristin is a valuable and versatile ingredient in the cosmetics and personal care industry due to its low boiling point, emollient properties, and stability. It is used in a wide range of products, including lotions, creams, makeup, and hair care products, to help improve the appearance and feel of the skin and hair.

If the nutmeg had been refluxed with water instead of hexane, would the experiment have been successful? Be sure to record a reference for where the data was found. TCI provides organic laboratory chemicals as well as pharmaceutical, cosmetic and functional materials. List sources of error to account for any discrepancy. BOC Sciences is a brand of BOCSCI Inc. A chemical formula of TRIMYRISTIN can therefore be written as: C45H86O6 The chemical formula of TRIMYRISTIN shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.
We leverage our wide spectrum of business in the fields of development, manufacturing, marketing, and distribution to help you make best-informed decisions tailored to your evolving needs for premium chemicals. The first recrystallization product can therefore be confirmed to be trimyristin and the slightly lower level in melting point suggests it is not yet a pure sample. Let the flask air dry for a few moments and If the flask is still not dry, repeat the above procedure. The liquid "bumps" and if it is flammable and an ignition source is near by, a fire can result. To find information about the expected yield of crude trimyristin from nutmeg, you should look up the listing for "nutmeg" , not the listing for "trimyristin".
Dispose of the distilled hexane in the appropriate dump in the fume hood make sure you know which flask contains the hexane. The above chemical formula is the basis of stoichiometry in chemical equations, i. However, since trimyristin can be isolated from more than one source, this listing will have nothing about the trimyristin content in nutmeg. In a future experiment, we will recrystallize the crude sample to obtain a fairly pure sample of trimyristin. Generally, the thermometer is placed so that the middle of the mercury bulb is even with the bottom of the side-arm. After the recrystallization, a melting point between 55-56 ° C is achieved for the product.
NEVER DISTIL TO DRYNESS. Determine the mass of your clean, dry 250 mL round bottom flask, containing a few boiling stones. Thus if you decrease the applied pressure by evacuating the system, you decrease the boiling point. Store this round bottom flask in your locker until it is purified in the next lab period. Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. TCI is a leading worldwide manufacturer of specialty organic chemicals founded in 1946. This should include the title of the book, the edition and the page number or the address if the internet was used.
The literature gives a melting point value of 54. You must then look up the two kinds of "oil of nutmeg" to determine which one contains the trimyristin. The product is not soluble in water and not easily dissolved in cold organic solvents. This book contains information about chemicals, natural products, plant extracts, etc. The percent yield after the first recrystallization was 25.
ALWAYS USE A BOILING CHIP. It consists of heating a liquid to its boiling point, at atmospheric or reduced pressure, to convert it to its vapour and then condensing the vapour back to the liquid by cooling. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula. For example, you might try the MERCK index. The range matches closely and the crude product upper limit is the same as the given lower limit for trimyristin. On the other hand do not overheat the system. Normally when the steam tap is first turned on, a quantity of water, which has condensed in the line, must be drained into the trough.
Also replace URL for the actual url of this page. This filtration should be done while the solution is still warm. When it is dry, however, some heat sources can quickly raise the temperature several hundred degrees and any high boiling liquids present are similarly overheated. The melting point for this product was between 54 and 56 ° C. To remove the remaining traces of crude product, you will need to use soap and HOT water scrub with a brush. In theory, the boiling point is independent of heat input but in practice, overheating of liquid and vapour occur if the heat input is excessive. The literature gives a melting point range of 56-57 ° C for trimyristin.

Set up the apparatus for simple distillation See the figure on page 124 and distil off the hexane using a steam bath. Definition ChEBI: A triglyceride obtained by formal acylation of the three hydroxy groups of glycerol by myristic tetradecanoic acid. A liquid will evaporate from the surface at any temperature. The main component of this mixture is the lipid, trimyristin, but there are many other components which will also be isolated along with the trimyristin. Remove the flask containing the crude product and weigh the flask. US Email: Email: Voice: Physical Properties: Assay: 95.
The flask can be swirled then the acetone poured out into the sink. An alternative textual expression including the structural information is InChI. The expected percentage can be found in a number of places. Over 30,000 Reagents available today in benchtop to bulk quantities. Some of the material was used for the hydrolysis, but what was used to recrystallize gave a 72. DUXYWXYOBMKGIN-UHFFFAOYSA-N 1357 The contents of this page can freely be shared if cited as follows: Source: Please hyperlink "Mol-Instincts" to.
Consequently, a slow, steady distillation rate should be maintained. Many organic solvents react slowly with air to form peroxides which may explode violently if overheated. . It is boiling when it is being converted to the vapour phase throughout its volume. In order to record the true boiling or vapour temperature, the thermometer must be correctly placed. In this experiment we shall isolate a mixture of oils from nutmeg. Email: US Email: Email: US Email: Voice: Moving Your Chemistry Forward We continuously strive to advance our technology.
