Many industries can see the existence of plant palmitic acid, such as: carbon paper, ball pen oil, printing and dyeing auxiliaries, etc., then what is plant fatty acid, how is plant palmitic acid made?
  The sodium or potassium salt of plant palmitic acid can be used as an emulsifier in emulsion polymerization. The sodium salt of plant palmitic acid is one of the main components of soap, and its aluminum and zinc salts are used in lubricants, coatings, inks and the like. In plasticizers. Industrial plant palmitic acid is obtained by saponification and neutralization of animal and vegetable oils such as butter, lard and palm oil. In the World War, derivatives of plant palmitic acid have been used to make napalm bombs. Plant stearic acid and stearic acid are mixed in a ratio of 45% to 55% to obtain a crystalline stearic acid product which can be applied to the cosmetics industry.
  1. Plant palmitic acid is stored in a clean and dry place, and should be sealed and stored. Pay attention to moisture, water and heat. Do not mix with strong oxidants. Plant palmitic acid can be stored in tin or stainless steel containers.
  2. The plant palmitic acid is packaged in aluminum drums or galvanized iron drums or in a phenolic resin lined storage tank. Plant palmitic acid should be protected from moisture, heat and water during storage and transportation. It is forbidden to put glycerin together with strong oxidants (such as nitric acid, potassium permanganate, etc.). Store and transport according to the general flammable chemicals regulations.
The amount of plant palmitic acid was diluted with 1/2 amount of distilled water. After stirring well, activated carbon was added and heated to 60-70 ° C for decolorization treatment, followed by vacuum filtration to ensure clear and transparent filtrate. The dropping rate is controlled, and the filtrate is added to a column of a previously prepared 732 type strong acid cation resin and a 717 type strong base yin and yang resin to adsorb and remove the electrolyte and aldehydes, pigments, esters and the like in the glycerin.
The glycerin solution after removing the plant palmitic acid impurities is subjected to vacuum distillation to control the degree of vacuum of 93326Pa or more, the pot temperature is 106-108 ° C, and most of the water is distilled off, and then the temperature of the kettle is raised to 120 ° C to rapidly dehydrate the water. The heating is stopped, and the obtained material in the kettle is the finished product.
