Pyruvic acid
Pyruvate is a part of the body that is involved in the metabolism of sugar and fat, and is one of the intermediate products of carbohydrate metabolism.
Pyruvate, the salt that it generates, is widely used in the field of medicine to produce sedatives, antioxidants, antiviral drugs, synthetic treatments for high blood pressure, and so on.
Pyruvate is also known as acetylformic acid, pyrographilic acid and 2-oxypropionic acid.
Light yellow to yellow transparent liquid.
It smells of acetic acid.
Have a sour taste.
Natural products are found in mint and sucrose fermentation.
Relative molecular mass 88.06.
The relative density of 1.2271.
The melting temperature of 13.8 ℃.
The boiling point of 165 ℃ (decomposition), and 106.5 ℃ (13.332 x 103 Pa), 85.3 ℃ (5.333 x 103 Pa), 70.8 ℃ (2.666 x 103 Pa), 57.9 ℃ (1.333 x 103 Pa), 45.8 ℃ (0.667 x 103 Pa), 21.4 ℃ (0.133 x 103 Pa).
Flash point is 82 ℃.
The refractive index of 1.4280.
Mixed with water, ethanol, ether, etc.
Color darkens in the air.
Slow heating polymerization, reactivity, easy and nitrides, aldehyde, halide, phosphide, such as reaction, to participate in the glucose metabolism of the organism, colloid, biochemical synthesis, such as amino acid, protein metabolism, alcohol fermentation, etc.
When pressed, it is reduced to lactic acid in the muscles, reoxidized and partially converted to glycogen during rest.
The rat is LD502100mg/kg.
Usage: used for medicine, amino acid (L - tyrosine substrate), and other synthetic, can improve the efficiency, especially in the pharmaceutical industry can shorten the process, simplify the process, such as the use of this product is made of 2 - phenyl cinchonine acid, is a kind of antipyretic analgesic, diuretic, use this product as a raw material, can greatly reduce the production cost;
It is also used as an anti-tb drug, calcium pyruvate, hormone synthesis, and insect repellent (Pyrunium pamote).
Also used in pesticide raw materials;
A biochemical reaction of pyruvate, indoles and ammonia, which produces tryptophan;
The production of monosodium glutamate, which can be used in order to improve the yield of l-suline;
Spices, the edible spices that were permitted in the country gb2760-1996.
Method:
The hydrolysis of acetone ester in the gas phase or liquid phase oxidation of lactic acid ester is further hydrolyzed.
2, tartaric acid as raw material, add potassium hydrogen sulfate and sodium bisulfate, heating to 210 ~ 220 ℃, dehydrogenation, available pyruvic acid crude products, recycling reduced pressure distillation refining.
3, with 2, 2-dichloropropionic acid as the raw material, use sodium hydroxide, adjust pH = 6, hydrolysis, can be made.
