N-Heptane CAS 142-82-5

N-Heptane has nine isomers, among which n-heptane [CH3(CH2)5CH3] is the most important. It is a colorless flammable liquid. It is almost insoluble in water, slightly soluble in alcohol, and soluble in ether and chloroform. Its vapor forms an explosive mixture with air, with an explosion limit of 1.0-6.0% (volume). It is separated from petroleum fractions. It vibrates violently when it burns and explodes in the cylinder. Its octane number is set to zero. Mixtures of various proportions with isooctane (octane number is set to 100) are often used as standards for determining the octane number of gasoline.

N-Heptane is a typical non-polar solvent, often used as a standard for determining octane number, anesthetic, organic synthesis raw material, etc. It is also widely used in the pharmaceutical, pesticide, rubber synthesis, chemical fiber synthesis, reagents, electronic cleaning and other industries. N-octane is used as a solvent and chromatographic analysis standard substance, and is also used in organic synthesis. With the rapid development of chemical, pharmaceutical, electronic and other related industries.

N-heptane is mainly used as a standard and solvent for octane number determination, as well as for organic synthesis and the preparation of experimental reagents. N-heptane is one of the most widely used hydrocarbon solvents in industry today. It is used as an extraction solvent for animal and plant oils and fats, and as a quick-drying rubber adhesive and rubber solvent. It is also used in the manufacture of cosmetics and as a solvent for cleaning coatings, paints, quick-drying inks and printing machine parts. Industrial-grade n-heptane is mostly obtained by separation of petroleum fractions and has a low purity.
