-Pesticide synthesis: In the pesticide manufacturing process, it can be used as an intermediate to participate in the synthesis of some compounds.
-Other applications: acid can also be used as a catalyst, dye intermediate, etc.
Preparation Method:
The preparation method of acid can usually be carried out through the following steps:
1.2-chlorothiophene reacts with excess sulfur dioxide to generate 2-chlorothiophene -3-ol.
2.2-chlorothiophene-3-ol reacts with an oxidizing agent (such as thionyl chloride) to generate 2-chlorothiophene-3-one.
3. React 2-chlorothiophene-3-one with alkaline solution to make acid.
Safety Information:
When using ICT, it is necessary to pay attention to safety operations, such as wearing protective gloves, glasses and respiratory protection, to avoid contact with skin, eyes or inhalation of its dust. In addition, it should be operated in a well-ventilated area to avoid breathing toxic gases. If accidentally contact or inhalation, should immediately rinse with plenty of water, and timely medical treatment.
