Properties and stability

flammable liquid with pungent odor.

Storage method

Stored at 2-8°C in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from acids and food chemicals, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.

Synthesis method

β-Hydroxyethyl methyl sulfide is dissolved in dry chloroform, Add dropwise a solution of thionyl chloride and chloroform. Keep stirring and heating when adding materials, and continue the reaction after adding materials4h SPAN>. Then evaporate to recover chloroform, distill under reduced pressure, and collect55-564.0kPa) fraction, get2-Chloroethyl methyl sulfide. Yield75-85%.

Purpose

Organic synthesis intermediates.
