Citric Acid Monohydrate CAS 5949-29-1

Citric acid monohydrate, also known as citric acid, citric acid, exists in nature in lemons, citrus, plums, plums, pears, peaches, figs and other fruits, with more immature acid content.

Citric acid monohydrate is colorless translucent crystal or white crystalline powder, easily soluble in water or alcohol solution, and can also be mixed with other ingredients to form an emulsion. Odorless, with a strong pleasant sour taste, it gradually weathers in warm air and deliquescent in moist air. According to different crystallization conditions, the crystal forms include anhydrous citric acid and citric acid containing crystal water.

Commercial citric acid is mainly anhydrous citric acid and citric acid monohydrate.

Citric acid monohydrate is crystallized from an aqueous solution at a low temperature (below 36.6°C), and the product is separated and dried. Placed in dry air, the crystal water in citric acid monohydrate will escape and weather.

Anhydrous citric acid is crystallized in an aqueous solution above 36.6 °C, and the critical temperature for the conversion of citric acid monohydrate to anhydrous citric acid is 36.6 °C.

Citric acid is a weak organic acid with a sour preference. Citric acid is commonly utilized in the food as well as beverage market as an acidity regulator and chemical.
