Manufacturing Process
Isohexanes are mixture of isomeric branched chain hexanes obtained by processing the C6 petroleum fraction with hydrogen in the presence of a catalyst. The product is derived from aliphatic sources and hence has low aromatic content.
Packing
Isohexane is available in ISO Tankers and 130 kg drums depending on the requirement.
Applications
Isohexane is a special boiling point solvent used in a variety of industries including :

What are the common uses and applications of isohexane?
Isohexane SBP is used in many industries including coatings, adhesives, lubricant aerosols, and as a solvent in organic synthesis, oil & gas, and drilling fluids. It is also used in manufacturing glues for leather, textiles, furniture, roofing, etc. Additionally, it can be used for cleaning precision instruments and electronics due to its volatility and solvent power
What is the boiling point of isohexane?
The boiling point of isohexane typically ranges from 60 °C to 63 °C (140 °F to 145 °F) depending on its exact isomeric composition and purity.
What is the difference between isohexane and n-hexane?
Isohexane is a branched isomeric mixture of hexanes, while n-hexane is the straight-chain isomer. Because of its branching, isohexane often has different solvent properties (e.g. lower solvency for some solutes) and typically lower toxicity profile. Isohexane grades often limit n-hexane impurity (e.g. < 3 %) to reduce undesirable effects
How should isohexane be stored and transported safely?
What grades or purity variants of isohexane are available?
One common grade is “Isohexane LNH,” a narrow-boiling-range version with low n-hexane content (< 3 %) and low aromatic/olefin content. Other grades are offered for analytical, high-purity, or residue-analysis use, with specifications on impurities, non-volatile matter, water content, etc.
What makes Isohexane SBP different from n-Hexane?
While both are C6 hydrocarbons, Isohexane SBP consists mainly of branched-chain isomers (2-methylpentane and 3-methylpentane), whereas n-Hexane is a straight-chain compound. Isohexane SBP has a lower aromatic content, reduced toxicity, and a more consistent boiling range, making it preferable in sensitive formulations and eco-friendly manufacturing.
Why is Isohexane SBP called a “Special Boiling Point” solvent?
The term “Special Boiling Point (SBP)” refers to solvents that have a narrow boiling range — in the case of Isohexane SBP, between 61°C and 62°C. This uniformity provides consistent drying and performance characteristics, crucial for precision formulations in coatings and adhesives.
How should Isohexane SBP be stored?
Store Isohexane SBP in cool, well-ventilated areas, away from heat, sparks, or flames. Keep containers tightly sealed, grounded, and away from oxidizing agents. Avoid prolonged exposure to sunlight or high temperatures to prevent vapor formation and product degradation.
Is Isohexane SBP miscible with water?
No. Isohexane SBP is immiscible in water but readily soluble in most organic solvents such as alcohols, ethers, and other hydrocarbons. This makes it ideal for blending with organic formulations and coatings.
Can Isohexane SBP replace n-Hexane in industrial applications?
Yes. In many cases, Isohexane SBP serves as a safer, less toxic alternative to n-Hexane, thanks to its low n-Hexane content (<1%) and lower neurotoxicity risk. It also offers more consistent evaporation for coating and adhesive formulations.
