Introduction
Ethyl thioacetate. The following is an introduction to the properties, uses, preparation methods and safety information of ethyl thioacetate:
Quality:
Ethyl thioacetate is a colorless liquid with a peculiar smelly and sour taste. It is volatile at room temperature and has a density of 0.979 g/mL. Ethyl thioacetate is soluble in many organic solvents such as ethers, ethanol, and esters. It is a combustible substance that produces toxic sulfur dioxide gas when exposed to heat or when exposed to an open flame.
Use:
Ethyl thioacetate is often used as a precursor compound for glyphosate. Glyphosate is an organophosphate insecticide widely used in herbicides, and ethyl thioacetate is required as an important intermediate in its preparation.
Method:
Ethyl thioacetate is usually prepared by esterification of ethanethioic acid with ethanol. For the specific preparation method, please refer to the manual of the organic synthesis laboratory.
Safety Information:
Ethyl thioacetate is irritating and corrosive and should be rinsed with plenty of water immediately after contact with skin and eyes. When in use or storage, it is necessary to ensure adequate ventilation and avoid contact with fire sources to prevent fire and explosion. When handling ethyl thioacetate, protective gloves, protective glasses, and protective clothing that are resistant to acids and alkalis should be worn to ensure personal safety. In case of accidental ingestion or inhalation, seek medical attention immediately.
