Pyridine Sulfur Trioxide (Pract) - Introduction
Sulfur trioxide pyridine complex is an organic compound with the chemical formula C5H5SO3. It is a colorless or pale yellow liquid with a pungent odor. The following is a description of the nature, use, preparation and safety information of Sulfur trioxide pyridine complex:
Nature:
- Sulfur trioxide pyridine complex is a strong oxidant that can oxidize with many organic compounds.
-it has a stimulating effect on the skin, eyes and respiratory tract, contact or inhalation can cause burning sensation, eye burning, sore throat and other discomfort symptoms.
Use:
- Sulfur trioxide pyridine complex is often used as an oxidant in organic synthesis. It can be used for the oxidation of aldehydes, ketones and other compounds to generate the corresponding acid.
-It can also be used for the synthesis of chemicals such as dyes, drugs, plastics and pesticides.
Method:
- Sulfur trioxide The preparation of pyridine complex is usually obtained by reacting pyridine with an excess of hydrogen peroxide at low temperature. The hydrogen peroxide produced during the reaction acts to oxidize pyridine.
Safety Information:
- Sulfur trioxide pyridine complex irritating and corrosive and should be used with appropriate personal protective equipment such as safety glasses, gloves and protective clothing.
-avoid direct contact with skin, eyes or inhalation of its vapor, such as inadvertent contact with discomfort symptoms, should immediately rinse with plenty of water, and seek medical help.
-in the use and storage process to avoid mixing with organic, reducing agent and other combustible substances, in order to prevent the occurrence of fire or explosion.
-Storage should be sealed and kept away from fire, high temperature and open flame.
