Application: Used to make dyes, drugs, spices, plasticizers, lubricants, etc., also used as preservatives, fungicide raw materials.
Production methods and others: natural products exist in nutmeg, lemon grass, apple, coconut oil, wine, hop, etc. Caprylic acid can be extracted from coconut oil by volatile fatty acid fractionation method. In industrial production, caprylic acid is produced by using octaldehyde as raw material. In laboratory preparation, n-hexylmalonic acid is heated to release carbon dioxide and reduced to 4-6.65kPa to make the reaction complete. Finally, the reaction product is distilled under vacuum, and the fraction collected at 127-129ºC (2.13kPa) is the caprylic acid. Yield 80-85. Caprylic acid can be prepared by the reaction of 1-octene and peracetic acid. There is also the oxidative dehydrogenation of n-octanol.
Common name amniotic acid, colorless transparent oily liquid. It smells of sweat. The relative density is 0.9105. Melting point 16ºC. Boiling point 239.7ºC. Refractive index 1.428. Slightly soluble in hot water, soluble in ethanol, benzene, ether. Used to make dyes, drugs, spices, plasticizers, lubricants and so on. It can also be used as a preservative, fungicide, etc. It is prepared by acidification and fractionation after saponification of coconut oil.
