3-Methylsulfolene Use and Manufacturing

Methods of Manufacturing

In the cooled autoclave, add equimolar isoprene and liquid sulfur dioxide, and then add methanol and an appropriate amount of hydroquinone. Heated in airtight, reacted at 85℃ for 4h, and after cooling, the reaction mixture was decanted, decolorized by activated carbon, concentrated and crystallized, and recrystallized from methanol to obtain product 3-methyl-3-cyclobutene sulfone.

Uses

Chemical intermediate, catalyst.
