1. This Citric Acid Anhydrous is a white translucent crystal or powder. It is odorless and tastes sour. The citric acid crystallized from the cold solution contains 1 molecule of water and becomes anhydrous in dry air or heated to 40-50℃. It is slightly deliquescent in humid air. It becomes soft at 75℃ and melts at 100℃. It is easily soluble in water and ethanol, and soluble in ether. It is flammable. It is insoluble in organic solvents such as chloroform and benzene. The aqueous solution is acidic. Citric acid is a strong organic acid that is highly corrosive to carbon steel but not to stainless steel. It can be oxidized to oxalic acid when in contact with strong oxidants (such as potassium permanganate); when melted with potassium hydroxide, it decomposes into oxalic acid and acetic acid.
2. anhydrous citric is non-toxic.
3. It exists in flue-cured tobacco leaves and burley tobacco leaves.
4. It exists in many natural plants such as lemons and citrus.
5. It is a strong organic acid.
6. It has two forms: anhydrous crystallization from hot water and monohydrate crystallization from cold water solution. Monohydrate can lose water in dry air.
