BENZENESULFONIC ANHYDRIDE - Introduction
Benzenesulfonicanhydride(Benzenesulfonicanhydride) is an organic compound with the chemical formula C6H5SO2O, which can be abbreviated as BSA. It has the following properties:
1. Appearance: The Benzenesulfonicanhydride is a white crystalline solid.
2. Solubility: It can be dissolved in organic solvents such as alcohol and ether under acidic conditions, but it is insoluble in water.
3. Stability: Benzenesulfonicanhydride is relatively stable at room temperature, but can be decomposed under high temperature or light.
The main uses of Benzenesulfonicanhydride include:
1. Chemical synthesis: It is an important organic synthesis reagent, which is used as the source of electrophilic sulfonic acid groups in organic synthesis reactions. It can react with an amine compound to generate the corresponding sulfonamide compound; or react with an alcohol to generate the corresponding sulfonate compound, etc. These reactions have important applications in the preparation of drugs, dyes, polymers and other compounds.
2. Corrosion inhibitor: Benzenesulfonicanhydride, as an organic corrosion inhibitor, can be added to metal corrosion protection coatings, paints, cleaning agents, etc., to reduce metal corrosion.
Benzenesulfonicanhydride preparation methods are mainly the following:
1. oxidation method: benzene sulfinic acid dissolved in acidic oxidant solution, such as concentrated sulfuric acid or nitric acid, adding ether solvent, reaction to generate Benzenesulfonicanhydride.
2. Reaction method: It is prepared by reacting benzene sulfinic acid with an appropriate reaction reagent under appropriate reaction conditions.
Benzenesulfonicanhydride have certain safety precautions:
1. Contact: Avoid direct contact with skin and eyes. If contact is made, rinse with plenty of water immediately.
2 inhalation: avoid inhalation of dust or gas, should be in a well ventilated place to operate.
3. storage: Benzenesulfonicanhydride should be stored in a dry, ventilated place, away from fire and oxidant.
4. Waste: Waste should be properly disposed of and comply with local regulations.
