Heptane is a common straight – chain alkane with the chemical formula C₇H₁₆, which forms a stable chemical structure through single bonds connecting seven carbon atoms and sixteen hydrogen atoms.
In terms of physical properties, heptane is a colorless and transparent liquid with a faint special odor. Its boiling point is approximately 98.4 degrees Celsius, the melting point is -90.6 degrees Celsius, and its density is less than that of water, about 0.684 grams per cubic centimeter at 20 degrees Celsius. Heptane is insoluble in water but easily soluble in organic solvents such as ethanol and ether.
As an important chemical raw material, heptane has various uses in laboratory and industrial fields. It is often used as an organic solvent to dissolve substances such as oils, rubber, and resins; in chemical analysis, heptane can be used as a standard substance to calibrate instruments and verify the accuracy of analytical methods.
It should be noted that heptane is flammable, and its vapor can form an explosive mixture with air, which is extremely easy to burn and explode when exposed to open flames and high heat. Therefore, during storage and use, it is necessary to keep away from fire sources and heat sources, maintain good ventilation, and take corresponding fire and explosion prevention measures to ensure safety.
