n-Heptane is a colorless and volatile liquid. It is mainly used as a standard for the determination of Octane number. It can also be used as anesthetics, solvents, raw materials for organic synthesis and experimental reagents , other applications include #Pharmaceuticals, #Paints & #Coatings, #Electronics, #Adhesives & #Sealants, #Plastic & #Polymers, #Laboratories.

Background and Overview
n-Heptane chemical formula C7H16. Molecular weight 100.20. There are nine isomers, of which n-Heptane [CH3 (CH2) 5ch3] is the most important. Colorless flammable liquid. Density 0.6837. Melting point – 90.5 ℃. Boiling point 98.4 ℃. Almost insoluble in water, slightly soluble in alcohol, soluble in ether and chloroform. Vapor and air form an explosive mixture, with an explosion limit of 1.0 ~ 6.0% (volume). Separated from petroleum fractions. It vibrates violently when burning and exploding in the cylinder. Its octane number is set to zero. Mixtures in various proportions with Iso-Octane (octane number is determined as 100) are often used as a standard for determining the octane number of gasoline. Toluene can be prepared by dehydrogenation and aromatization of n-Heptane, which is a common solvent. At present, n-Heptane is mainly produced by distillation in industry. Because the boiling points of n-heptane and C7 fractions are very similar (e.g. n-Heptane boiling point 98.43 ℃, methyl Cyclohexane boiling point 100.93 ℃, and the boiling point difference is only 2.5 ℃), it is difficult to separate them by ordinary distillation; Precision distillation has the advantages of high energy consumption, high production cost, low yield, and it is difficult to obtain high-purity n-Heptane (> 99%); With special distillation method, the cost is high and the process is complex.
n-Heptane is a typical nonpolar solvent. It is often used as a standard for determining octane number, anesthetic, organic synthetic raw material, etc. it is also widely used in medicine, pesticide, rubber synthesis, chemical fiber synthesis, reagent, electronic cleaning and other industries. n-Octane is used as solvent and chromatographic reference material, as well as organic synthesis. With the rapid development of chemical industry, medicine, electronics and other related industries, the demand for n-Heptane in the world will increase year by year, especially High-Purity n-Heptane has broad market prospects.
