Hexane

The IUPAC name of n-Hexane is hexane. With the CAS registry number 110-54-3, it is also named as Dipropyl. The product's categories are Analytical Chemistry; Solvents for HPLC & Spectrophotometry; Solvents for Spectrophotometry; Anhydrous Solvents; Synthetic Organic Chemistry; n-Paraffins (GC Standard); Standard Materials for GC. It is clear colorless liquids with a petroleum-like odor that is stable, incompatible with oxidizing agents, chlorine, fluorine, magnesium perchlorate. And n-Hexane is highly flammable, so people should keep it away from sources of ignition. What's more, it may be sensitive to light and may also be sensitive to prolonged exposure to heat.  

The other characteristics of n-Hexane can be summarized as: (1)ACD/LogP: 3.76; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 3.764; (4)ACD/LogD (pH 7.4): 3.764; (5)ACD/BCF (pH 5.5): 427.313; (6)ACD/BCF (pH 7.4): 427.313; (7)ACD/KOC (pH 5.5): 2658.84; (8)ACD/KOC (pH 7.4): 2658.84; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 3; (12)Index of Refraction: 1.384; (13)Molar Refractivity: 29.846 cm³; (14)Molar Volume: 127.576 cm³; (15)Polarizability: 11.832×10^-24 cm³; (16)Surface Tension: 20.32 dyne/cm; (17)Enthalpy of Vaporization: 28.85 kJ/mol; (18)Vapour Pressure: 150.927 mmHg at 25°C; (19)Rotatable Bond Count: 3; (20)Exact Mass: 86.10955; (21)MonoIsotopic Mass: 86.10955; (22)Heavy Atom Count: 6; (23)Complexity: 12.

Preparation of n-Hexane: It is produced by the refining of crude oil. The exact composition of the fraction depends largely on the source of the oil (crude or reformed) and the constraints of the refining. The industrial product (usually around 50% by weight of the straight-chain isomer) is the fraction boiling at 65–70 °C.

Uses of n-Hexane: It is used in solvents to extract oils for cooking and as a cleansing agent for shoe, furniture and textile manufacturing. It is mostly used in gasoline. They are also used as a solvent and as a medium for various polymerization reactions. A typical laboratory use of hexanes is to extract oil and grease contaminants from water and soil for analysis. In addition, n-Hexane can react with hex-1-ene to get benzene. This reaction needs reagent H₂ and catalytic agent Pt-Re/h-Al₂O₃ at temperature of 510 °C. The yield is 60%.

When you are using this chemical, please be cautious about it as the following:
