Uses and Applications

Mainly used as a solvent and for extracting oils and fats.

Used as an organic solvent and chromatographic analysis solvent; used as a high-efficiency organic solvent, pharmaceutical extractant, and fine chemical synthesis aid; also used in organic synthesis and as a chemical raw material.

It is used in organic synthesis and chemical raw materials, such as in the production of synthetic rubber, plastics, nylon monomers, synthetic detergents, and pesticides. It is also an excellent organic solvent. Primarily used as a solvent, it is also used as a foaming agent for foamed plastics and as an extractant for pharmaceuticals and fragrances.
