Introduction
2-Methyl-3-tetrahydrofuran mercaptan, commonly known as MTST or MTSH, has the following properties:
Appearance: Colorless to light yellow liquid.
Odor: Has a special taste of hydrogen sulfide.
Density: approx. 1.0 g/cm³.
Its main uses are as follows:
Ionic liquid preparation agent: MTST can be used as a solvent and additive for the preparation of ionic liquids.
Industrial uses: MTST is commonly used as a reducing agent and chelating agent in industrial processes such as metal cleaning, surface treatment and electroplating.
Preparation method of MTST:
The common preparation method is to react methiophenol with reagents such as magnesium methyl bromide or copper methyl bromide in tetrahydrofuran or other appropriate solvents to obtain the target product.
Safety Information for MTST:
Very toxic: MTST is irritating and corrosive to the skin, eyes, and respiratory system, and proper protective equipment must be used.
Flammable: MTST is a flammable liquid, and fire sources and high temperatures should be avoided when stored and used.
Avoid prolonged exposure: Prolonged exposure to MTST can lead to poisoning and other health problems, and prolonged exposure should be avoided as much as possible.
Storage and Handling: MTST should be stored in an airtight container, away from ignition and oxidants. Waste liquids and containers should be disposed of in accordance with local regulations.
When using and handling MTST, it is important to understand and comply with relevant safety operating procedures and regulations.
