White to yellowish-white hard solid, occasionally shiny crystalline solid, or white to yellowish-white powder, odorless.

Tetradecanoic acid can be obtained by vacuum fractional distillation of mixed fatty acids or methyl esters of mixed fatty acids obtained from coconut oil and palm kernel oil. Laboratory preparation can be saponified by glycerol tris (tetradecanoic acid) ester and 10% sodium hydroxide solution, and then acidified with hydrochloric acid to obtain free tetradecanoic acid. It can also be obtained by tetradecanol method.
Mainly used as a raw material for the production of surfactants, used in the production of sorbitan fatty acid esters, glycerol fatty acid esters, ethylene glycol or propylene glycol fatty acid esters. It can also be used to produce isopropyl myristate and so on. It is also used as defoamer and flavor enhancer. According to our GB2760-89 regulations can be used to formulate a variety of edible spices.

Endosperm cells polygonal, containing a large amount of fat oil, starch particles and paste powder particles, paste powder particles in the proposed crystals. The endosperm has scattered cells containing brown material.
