Phosphomolybdic acid - Upstream Downstream Industry
Phosphomolybdic acid - Introduction
Phosphomolybdic acid, chemical formula H3[PMo12O40], is an inorganic compound. Its nature is as follows:
1. Appearance: Phosphomolybdic acid is a colorless or pale yellow crystalline powder, soluble in water and alcohol solvents.
2. Acidity: Phosphomolybdic acid is a strong acid that can react with metal ions or salts.
3. Catalytic properties: Phosphomolybdic acid plays an important role in the catalyst, which can catalyze oxidation reaction, esterification reaction, olefin isomerization reaction and so on.
4. Chemical stability: Phosphomolybdic acid is relatively stable at room temperature, but it will decompose under the action of strong acid or strong oxidant at high temperature.
The application of Phosphomolybdic acid mainly includes the following aspects:
1. Catalyst: widely used in the chemical industry as an oxidant, esterification agent and olefin isomerization reaction catalyst.
2. Analytical reagents: Phosphomolybdic acid can be used to detect aluminum, phosphate, sugars and lipids and other substances.
3. Treatment: Phosphomolybdic acid can be used to treat certain diseases, such as lymphoma.
4. Dye: Phosphomolybdic acid can be used as a component of dyes and pigments.
There are two main methods for preparing Phosphomolybdic acid:
1. Solution method: Molybdate and phosphoric acid are reacted at an appropriate temperature, and then Phosphomolybdic acid is obtained by evaporating water.
2. Solid State method: directly mix molybdate and phosphoric acid at high temperature for reaction, and then obtain Phosphomolybdic acid by cooling crystallization.
Regarding safety information, Phosphomolybdic acid is a strong acid and is corrosive. In the use and storage need to pay attention to the following matters:
1. Avoid direct contact with skin and eyes. If contact occurs, rinse immediately with plenty of water.
2. On skin and eye irritation, should pay attention to the use of protective measures, such as wearing protective glasses and gloves.
3. In the use of Phosphomolybdic acid, to maintain good ventilation conditions.
4. Phosphomolybdic acid should be stored in a dry place, separated from flammable materials and oxidants.
5. When dealing with Phosphomolybdic acid waste liquid, it is necessary to carry out safe disposal in accordance with relevant regulations.
