Stability
1. White translucent crystals or powder. Odorless, sour, citric acid crystallized from cold solution contains 1 molecule of water, which becomes Anhydrous in dry air or heated to 40-50 ℃. Slightly deliquescent in humid air. It becomes soft at 75 ℃, melts at 100 ℃, is easily soluble in water and ethanol, and is soluble in ether. Flammable. Insoluble in organic solvents such as chloroform and benzene. The aqueous solution is acidic. Citric acid is a strong organic acid that has a strong corrosive effect on carbon steel, but does not corrode stainless steel. It can be oxidized to oxalic acid in case of strong oxidant (such as Potassium permanganate); When fused with potassium hydroxide, it decomposes into oxalic acid and acetic acid.
2. This product 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.
