Citric acid is an important organic acid, also known as citric acid, colorless crystals, often containing one molecule of crystal water, odorless, has a strong sour taste, soluble in water. Its calcium salt in hot water than in hot water is easy to dissolve, this property is often used to identify and isolate citric acid. Anhydrous citric acid can be obtained by controlling the temperature at the time of crystallization. In industry, food industry, cosmetics industry has many uses.
Physical and chemical properties
Physical properties At room temperature, citric acid is colorless semipermeable Crystal or white particles or white crystalline powder, odorless, very sour taste, in the humid air slightly deliquescence. It can be in the form of anhydrous or monohydrate: citric acid from hot water crystallization, the formation of non-hydrate; crystallization in cold water to generate a hydrate. Heating to 78 ° C when a hydrate will be decomposed to anhydrous. At 15 degrees Celsius, citric acid can also be dissolved in anhydrous ethanol. Citric acid crystal morphology due to different crystallization conditions are different, there is anhydrous citric acid C6H8O7 also contains crystalline water citric acid 2C6H8O7.H2O, C6H8O7.H2O or C6H8O7.2H2O.
Chemical properties Structurally speaking, citric acid is a tricarboxylic acid compound and therefore has similar physical and chemical properties to other carboxylic acids. Heated to 175 ° C It decomposes to produce carbon dioxide and water, leaving some white crystals. Citric acid is a strong organic acid, there are three H + ionization; heating can be decomposed into a variety of products, and acid, alkali, glycerol and other reactions.
