Ascorbic acid is a white, odorless substance with a sour taste. It is an organic compound similar in structure to glucose.
It is considered to be one of the vital nutrients of the human diet, which ensures the normal state of bone and connective tissues. Vitamin C is a reducing agent and coenzyme for a number of metabolic processes, and is also considered an antioxidant.
Ascorbic acid is easily soluble in alcohols - methanol and ethanol, water; slightly soluble in glycerin, acetone; soluble in benzene, petroleum and ordinary ether, chloroform. Aqueous solutions of vitamin C correspond to pH ~ 3, they act as a monobasic acid, and are stable in the absence of oxygen. In air, the stability of solutions is noted at a pH level of 5-6; in an alkaline environment, they are completely unstable.
Melting and decomposition of ascorbic acid occurs at a temperature of 189-193°C. In solid form, the connection is stable. It is an active reducing agent, very easily oxidized by most oxidizing agents. A large amount of natural vitamin C is found in citrus crops, fruits, and vegetables.
The production of ascorbic acid is based on the catalytic hydrogenation of D-glucose to D-sorbitol followed by its oxidation by Acetobacter suboxydans bacteria to L-sorbose. After acetonation and oxidation of intermediate products, ascorbic acid is obtained, the amount of which is approximately 50% by weight of the raw material taken.
The chemical formula is C 6 H 8 O 6 .
