Molecular formula : C10H12O5
MW : 212.20
CAS No. :121-79-9
nature : the white powder. 150 ° C melting point. Ether is very soluble in alcohol and slightly soluble in water. 1g the goods soluble 400ml25 ° C water, the pH of about 5.5. The goods more stable to heat, and iron and coloring reaction.
Preparation : gallic acid esterification with propanol derived. Will gallic acid, alcohol, benzene, sulfuric acid and p-toluenesulfonic acid to join enamelled 11:50, heating dehydration, the recovery of benzene, placed 2h. Add the water and then placed 24h. Rejection filter to be crude, rough materials dissolved in ethanol, filtration, the filtrate added to the water crystallization, filtration, drying derived products.
purposes : the goods of food and feed additives. For grease, lard, etc. Hang oxidant - antioxidant role, but coloring shortcomings, the following amount of MNC. As feed antioxidants, the biggest amount of 100ppm. Can also be used for cosmetics. Rat oral LD50 of updraft.
