二苯(甲氧基甲基)氧化膦 - Reference Information
| traits | white crystal or crystalline powder |
| properties | L-malic acid is a form that organisms can use. it is often mixed with compound amino acid injection (an important nutritional drug after surgery) to improve the utilization rate of amino acids, which is especially important for patients with postoperative weakness and liver dysfunction. Potassium L-malate is a good potassium supplement. It can maintain the body's water balance and treat edema, hypertension and fat accumulation. L-malic acid is a good drug for the treatment of liver disease, especially hyperammonemia caused by liver dysfunction. Sodium L-malate has 1/3 of the salty taste of salt and can be used as a substitute salt for kidney patients. |
| introduction | malic acid is a white or fluorescent white powdery, granular or crystalline solid. The crystal does not contain crystal water, DL-type melting point is 129 degrees Celsius, L-type melting point is 100 degrees Celsius, heating to 180 degrees Celsius can lose water and decompose into fumaric acid or maleic acid. Under normal conditions, malic acid is stable, but its pure crystals are slightly hygroscopic and may liquefy under high temperature conditions. Malic acid is a strong organic acid. Because it contains an asymmetric carbon atom, malic acid has optical activity, but its optical activity has dilution effect. Natural malic acid is particularly prominent in this respect. Malic acid can undergo esterification reaction with alcohol in the presence of catalyst. Using boron trifluoride as a catalyst and refluxing with alcohols can form monoesters; interacting with polyols and aromatic polycarboxylic acids can form resin products, such as alkyd polyester resins; |
| use | (1) food industry: used for processing and configuring beverages, wine, fruit juice, also used for the manufacture of candy, jam, etc., and has antibacterial and antiseptic effects on food. It can also be used for pH adjustment of yoghurt fermentation and tartrate in wine brewing. (2) Tobacco industry: Malic acid derivatives (such as esters) can improve tobacco fragrance. (3) Pharmaceutical industry: All kinds of tablets and syrups with malic acid can be fruity flavor, and is conducive to absorption and diffusion in the body. (4) Daily chemical industry: it is a good complexing agent and ester agent, which is used for toothpaste formula, tooth cleaning tablet combination, synthetic perfume formula, etc., and can also be used as an ingredient of deodorant and detergent. |
