20590-32-3 - Introduction
MEAD acid, also known as formic acid 5,6,7,8-tetracarboxylic acid, is an organic acid. The following is an introduction to the properties, uses, preparation and safety information of MEAD acid:
Nature:
- MEAD acid is a colorless crystalline solid, almost insoluble in water, but can be dissolved in organic solvents.
-It has strong acidity and can react with alkali to generate the corresponding salt.
- MEAD acid has high thermal stability and can be used under high temperature conditions.
Use:
- MEAD acids are commonly used as intermediates in organic synthesis for the synthesis of other compounds such as dyes, fragrances and pharmaceuticals.
-It can also be used as a catalyst for polymer reactions.
Preparation Method:
- MEAD acid can be synthesized by oxidizing formic acid. A common preparation method is to react formic acid with sulfuric acid or manganese sulfate solution to form MEAD acid.
Safety Information:
- MEAD acid is less toxic, but still need to comply with laboratory safety procedures.
-It should be kept away from open flames and high temperatures, and avoid contact with skin and eyes.
-Wear appropriate protective equipment, such as lab gloves and glasses, when handling or storing MEAD acid.
-If inhaled or ingested MEAD acid, seek medical help immediately.
