Di-n-butyl sulphoxide - Introduction
n-Butyl sulfoxide(n-Butyl sulfoxide) is an organic compound with the molecular formula C4H9SO. In the structure, there is an n-butyl (butyl) group connected to a sulfoxide group.
n-Butyl sulfoxide can be widely used as a solvent and intermediate in the chemical industry and laboratory. It has high solubility, can dissolve many organic and inorganic compounds, and is suitable for dissolving insoluble substances, extracting organic compounds and catalytic reactions. In addition, n-Butyl sulfoxide can also be used as a reducing and oxidizing agent in biochemical research.
The method for preparing n-Butyl sulfoxide is generally to react n-butanol with thionyl chloride to generate sulfoxide compounds, and then react with sulfurous acid to prepare n-Butyl sulfoxide.
In terms of safety, n-Butyl sulfoxide is a chemical, it is necessary to pay attention to the safe operation. It will burn at high temperature, open flame or organic fire, so it should be away from high temperature, fire source and open flame. At the same time, n-Butyl sulfoxide has certain toxicity, avoid inhalation of gas, mist or dust, and avoid contact with skin or eyes. In case of careless contact, rinse the corresponding parts with water immediately and seek medical treatment in time.
Therefore, the use of n-Butyl sulfoxide should follow the correct operating procedures, and take the necessary safety measures, such as wearing protective gloves, safety glasses and protective masks, operate in a well-ventilated environment.
