1-Tetradecanol, or commonly myristyl alcohol (from Myristica fragrans – the nutmeg plant), is a straight-chain saturated fatty alcohol, with the molecular formula C14H30O. It is a white crystalline solid that is practically insoluble in water, soluble in diethyl ether, and slightly soluble in ethanol.

1-Tetradecanol may be prepared by the hydrogenation of myristic acid (or its esters); myristic acid itself can be found in nutmeg (from where it gains its name) but is also present in palm kernel oil and coconut oil and it is from these that the majority of 1-tetradecanol is produced.[2] It may also be produced from petrochemical feedstocks via either the Ziegler process or hydroformylation.

As with other fatty alcohols, 1-tetradecanol is used as an ingredient in cosmetics such as cold creams for its emollient properties. It is also used as an intermediate in the chemical synthesis of other products such as surfactants.

  • Carrying out a melting point determination


We're going to get a melting point of this compound we've just recrystallised. A melting point tube can be made by sealing the end of a capillary tube. Hold the tube at 45 degrees with the end at the top of the blue cone of the Bunsen flame, and gently turn the tube. You want to seal the end, but not heat it so much that a glass ball is formed on the end of the tube. This will make it hard to insert into the melting point apparatus. The easiest way to get your compound into the melting point tube, is to put a small amount on to a watch glass, and press the open end of the tube on to the solid, to create a small plug in the end of the tube. You can either flick the tube, or bounce it gently on the bench to get the solid to the bottom of the tube. You only need a few crystals. Put it into the melting point apparatus and turn the heater to three or four. Don't be tempted to turn it to nine or ten as you will over shoot the melting point and you'll get an inaccurate value. Don't be tempted to use rapid heat either for the same reason. Watch the solid until you just see it started to shrink from the side of the tube and that's the first sign is starting to melt. You need to take a range for the melting point so record temperature which it starts and finishes melting.
