diazoacetic acid - Introduction
diazoacetic acid is an organic compound with the chemical formula C2H2N2O2. It is a colorless crystalline solid, stable at room temperature, but prone to explosion. The following is an introduction to the nature, use, formulation and safety information of diazoacetic acid:
Nature:
1. diazoacetic acid is unstable and easily separated to release toxic nitrogen.
2. It has strong oxidation and flammability, and can cause fire or explosion when encountering combustibles and flammable substances.
3. diazoacetic acid can only be slightly soluble in water, but soluble in alcohols and ether solvents.
Use:
1. diazoacetic acid can be used as an important intermediate in organic synthesis reactions, such as for the synthesis of other diazo compounds and diazo esters.
2. it can also be used for the synthesis of antibiotics, amides, hydroxylamine and other organic compounds.
Preparation Method:
1. diazoacetic acid is usually synthesized by diazotization reaction. First, tartaric acid and sodium nitrite or potassium nitrite are reacted to form a diazo compound. The diazo compound is then reacted with acetic acid to produce the diazoacetic acid.
2. this process needs to be carried out at low temperature, and take corresponding safety measures to prevent accidents.
Safety Information:
1. diazoacetic acid is toxic and flammable, contact or inhalation of its vapor may cause harm to human health.
2. Wear appropriate protective equipment such as gloves, goggles and protective clothing when using diazoacetic acid.
3. Avoid mixing with combustibles and combustible substances to avoid fire or explosion.
4. Waste shall be disposed of in accordance with local regulations and shall be stored and transported with appropriate protective measures.
