General description
Application
- As a solvent for the extraction of aromatic sulfur compounds.
- A mixture of heptane/acetone solvent system used in the chromatographic purification of organic compounds.
- Heptane/ionic liquid two-phase solvent system used to synthesize isoamyl acetate via esterification reaction using lipase as a catalyst.
- As a weakly polar diluent to prepare mobile phase for thin-layer chromatography (TLC).
- In the synthesis of SBA-15, heptane can be used as a pore swelling agent in combination with NH4F to control the particle morphology and pore size of SBA-15.
