n-Heptane is a colorless, transparent liquid with a faint gasoline odor. It is immiscible with water but freely miscible with ethanol, diethyl ether, acetone, chloroform, benzene and carbon tetrachloride. The substance has a melting point of \u201391 \u00b0C, a boiling point of 98 \u00b0C, a density of 0.71 g cm\u207b\u00b3 at 20 \u00b0C, and a flash point of \u20134 \u00b0C, classifying it as highly flammable with an explosive range of 1.05\u20136.7 % v\/v in air.<\/p>\n

It is employed as a reaction medium in organic synthesis for Grignard and Friedel-Crafts reactions, as a cleaning agent for electronic components and precision instruments, and as a carrier solvent in adhesives, coatings and rubber processing. Laboratories use it for recrystallization, polymer fractionation and as a standard in calibrating analytical instruments.<\/p>\n 4. l'emballage et le stockage<\/h3>\nSmall opening steel drum Ordinary wooden case outside the ampoule; Threaded mouth glass bottles, iron cap pressed mouth glass bottles, plastic bottles or metal drums (cans) in ordinary wooden cases.During transportation, the transport vehicles should be equipped with the corresponding types and quantities of fire-fighting equipment and leakage emergency handling devices. It is best to transport in the morning and evening during summer. The tank (cabinet) vehicles used for transportation should have grounding chains, and holes and partition boards can be set inside the tank to reduce static electricity caused by vibration. It is strictly prohibited to mix and transport with oxidants, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures.<\/p>","protected":false},"excerpt":{"rendered":" Molecular formula: C\u2087H\u2081\u2086 CAS: 142-82-5 Relative molecular mass: 100.203 Structural formula: 1.Product Property n-Heptane is a colorless, transparent liquid with a faint gasoline odor.
