2,4,5,6-TETRAMETHYLBENZENEDISULFONYL DICHLORIDE - Introduction

Tetramethylbenzenedisulfonyl dichloride is an organic compound with the chemical formula C12H14Cl2O4S2. It is a colorless solid with a strong pungent odor.

Tetramethylbenzenedisulfonyl dichloride are mainly used as intermediates in organic synthesis. It can be used to synthesize organic compounds containing disulfonate, such as disulfonate drugs, dyes and colloidal materials. In addition, it can also be used for polymer crosslinking and surfactant synthesis.

The preparation Tetramethylbenzenedisulfonyl dichloride is usually obtained by reacting 2,4,5,6-tetramethylbenzenedisulfonic acid with thionyl chloride. 2,4,5,6-tetramethylbenzenedisulfonic acid was first dissolved in dimethyl sulfoxide and then thionyl chloride was slowly added. After completion of the reaction, the product was purified by distillation and crystallization.

Regarding safety information, Tetramethylbenzenedisulfonyl dichloride are irritating and corrosive to the skin and eyes. Appropriate safety precautions should be taken during operation, such as wearing protective glasses, gloves and suitable protective clothing. At the same time, it should be operated in a well-ventilated place to avoid inhaling its vapor or dust. IF THE COMPOUND IS CONTACT, RUSH IMMEDIATELY WITH WATER.
