Property description: White pearlescent scales. Melting point 63-64℃, boiling point 351.5℃, 267℃ (13.3kPa), relative density 0.835 (62/4℃), refractive index 1.4273 (80℃). Slightly soluble in cold alcohol and petroleum ether, soluble in ethanol, easily soluble in ether, chloroform and acetic acid, only 0.00072g dissolved in 100ml water.
Production method: there are palmitic acid components in almost all oils and fats. The content of palmitic acid can be as high as 60% in tallow oil, while the content of palm oil in palm fruit is about 40%, but the content of rape oil is less than 2%. Palmitic acid was obtained from unsaturated fatty acids separated by hydrolysis, fractionation and pressing of tallow oil or palm oil through recrystallization. Commercially available palmitic acid generally melts at 57.5-62.5℃.
Use: raw material of candle, soap, grease, softener and synthetic detergent. Palmitic acid is used to produce chloramphenicol odorless and various metal salts of palmitic acid, its sodium salt or potassium salt can be used as emulsifiers in emulsion polymerization, aluminum salt and zinc salt are used in lubricants, coatings, oil black and plasticizers. The product has a special aroma and taste, according to the provisions of GB2760-89, can be used to prepare various edible spices, also used as defoaming agent and other food additives raw materials.
