4675-64-3 - Introduction
potassium hydrogen malate is a colorless crystalline solid with the chemical formula C4H5KO5 and its molecular structure is composed of malic acid and potassium hydroxide. It is acidic, soluble in water and ethanol, insoluble in ether.
potassium hydrogen malate has a variety of uses. First, it is a food acidulant, often used as a sour enhancer and flavoring agent in foods and beverages. Secondly, it can also be used in pharmaceutical preparations, often as an acidic stabilizer and buffer. In addition, potassium hydrogen malate can also be used in the treatment and modification of cellulose and fiber products to enhance their water resistance.
potassium hydrogen malate can be obtained by the reaction of malic acid with potassium hydroxide. First, malic acid and an appropriate amount of potassium hydroxide are dissolved in water, and a solution of potassium hydrogen malate is generated during the reaction. Then, a colorless crystal of the potassium hydrogen malate was obtained by the steps of crystallization and drying.
When using potassium hydrogen malate, you need to pay attention to the following safety information. First of all, it is an irritating substance to the eyes, so direct contact with the eyes should be avoided. Second, avoid swallowing or prolonged exposure to the skin to avoid irritation or allergic reactions. During storage and transportation, care should be taken to avoid contact with acids, oxidants, metal powders and other substances to avoid unsafe chemical reactions. Finally, when handling and using potassium hydrogen malate, care should be taken to wear appropriate protective equipment, such as gloves, glasses, etc. If accidental contact or eating, please timely medical treatment.
