Fatty acid), also called palmitic acid, is a saturated higher fatty acid, white with pearlescent phosphorus flakes. Insoluble in water, slightly soluble in petroleum ether, soluble in ethanol. Easily soluble in ether, chloroform and acetic acid.
It is widely found in nature, and almost all oils have varying amounts of hexadecanoic acid (palmitic acid) component. The content of palmitic acid in my country’s specialty tallow tree oil can be as high as 60%, while the content in palm oil from palm tree fruits is about 40%, but the content in rapeseed oil is less than 2%. Palmitic acid is obtained by hydrolyzing tallow oil or palm oil, fractionating, and pressing to separate unsaturated fatty acids, and then recrystallizes them. Commercially available palmitic acid generally has a melting point of 57.5-62.5°C.
The following suppliesHexadecanoic acid (palmitic acid) will take you to learn about its uses: strong>
1. Used as precipitating agent, chemical reagent and waterproofing agent
2. Defoaming agent; raw material for manufacturing other food additives (fatty acid glycerides, fatty acid sorbitan esters, sugar esters, etc.). It can also be used as a spice ingredient. According to FEMA regulations, the maximum dosage in seasonings is 1.0mg/kg.
3. Raw materials for the production of candles, soaps, greases, softeners and synthetic detergents.
4. Palmitic acid is used to make odorless chloramphenicol and various palmitic acid metal salts. Its sodium or potassium salts can be used as emulsion polymerization agents. Emulsifiers, aluminum salts and zinc salts are used in lubricants, coatings, oil blacks and plasticizers.
5. Used as standard material for gas phase analysis
6. Determine the hardness of water and calcium, magnesium, barium, lead, mercury, zinc. Organic synthesis, manufacturing various palmitic acid metal salts and waterproofing agents.
