How Are C6 Aliphatic Hydrocarbons Applied

Hexene is an organic compound that belongs to the alkene family. Its chemical formula is C6H12, where “hex” refers to six carbon atoms and “ene” indicates the presence of a double bond. Because of this structure, hexene is reactive and useful in many industrial processes. 

In commercial settings, hexene is often supplied as mixed hexene, which is a blend of different hexene isomers. It appears as a clear, colourless liquid with a petroleum-like odour. It is volatile, flammable, insoluble in water, and highly soluble in common organic solvents. These traits explain why C6 aliphatic hydrocarbons like mixed hexene find use across multiple industrial and chemical applications. 

This guide explains what mixed hexene is, the properties that drive its use, key industrial hexene applications, and what buyers should look for when sourcing from 1-hexene suppliers. 

What is Mixed Hexene and How Does It Differ From Single-Isomer Hexenes? 

The term “hexene” does not describe a single compound. It refers to a group of isomers, all sharing the formula C6H12 but differing in the position of the double bond. 

1-hexene is an alpha-olefin, where the double bond is located at the end of the carbon chain. 2-hexene, on the other hand, is an internal olefin, with the double bond positioned between internal carbon atoms. These structural differences affect reactivity and performance in downstream processes. 

Mixed hexene contains a combination of these isomers rather than one purified form. This makes it suitable for applications where exact isomer purity is not critical, but consistent physical and chemical behaviour is important. Because it behaves like a volatile hydrocarbon stream, its use is often guided by composition, boiling range, and handling properties rather than by a single molecular structure. 

Key Properties That Make C6 Aliphatic Hydrocarbons Useful 

C6 aliphatic hydrocarbons such as mixed hexene are widely used in industrial settings because their physical and chemical characteristics strike a practical balance between performance and handling. 

Volatility and flammability 

Hexene typically boils in the range of 60–80°C. This level of volatility makes it easy to evaporate and manage during processing, which is helpful in many operations. At the same time, it also means that appropriate storage and safety measures are essential due to its flammable nature. 

Solvent compatibility 

Mixed hexene does not dissolve in water, but it blends readily with ethanol, benzene, petroleum ether, and other organic solvents. This behaviour makes it especially suitable for organic-phase reactions and blending processes where water compatibility is not required. 

Typical quality indicators 

In standard commercial supply, mixed hexene appears as a clear, colourless liquid. The APHA colour is generally maintained at not more than 20 Hazen. Its specific gravity is around 0.660 at 25°C, and the flash point is close to 4°C using the closed cup method. 

Together, these parameters play an important role in determining how mixed hexene is stored, transported, and chosen for different industrial hexene applications. 

How Hexene Is Manufactured 

Hexene is most commonly produced through ethylene oligomerization. In this process, ethylene molecules are combined under controlled conditions to form longer-chain olefins with even numbers of carbon atoms. 

From a buyer’s perspective, this production route is important because it directly influences: 

• The distribution of hexene isomers 

• Overall impurity levels 

• Batch-to-batch consistency 

For many industrial users, consistent composition matters more than isolating a single hexene isomer, especially when the material is used as a feedstock or processing aid. 

Industrial Hexene Applications Where Mixed Hexene Fits 

Mixed hexene is generally selected for its predictable physical behaviour and flexibility, rather than for highly specific chemical reactivity. 

Chemical intermediate feedstock 

Mixed hexene can serve as a C6 olefin stream in downstream chemical synthesis where strict isomer separation is not required. In such cases, buyers typically focus on GC composition, distillation range, and impurity limits rather than single-isomer purity. 

Process aid and solvent-like hydrocarbon stream 

Because it dissolves well in organic systems and remains insoluble in water, mixed hexene can function as a solvent-like component in blending and processing operations. Its volatility also makes it easier to remove from the system when required. 

Energy and fuel-related contexts 

In certain regulated environments, parameters such as vapour pressure and octane number may be referenced during technical evaluations. These values are generally used for assessment purposes rather than as broad suitability claims. 

Note on 2-Hexene Applications 

Internal olefins such as 2-hexene are sometimes discussed separately due to differences in reactivity when compared with alpha-olefins. If a downstream reaction is sensitive to the position of the double bond, confirming the isomer distribution within mixed hexene becomes especially important. 

In practice, mixed hexene is often chosen when a controlled mixture offers greater practicality than sourcing a highly purified individual isomer. 

What to Check When Evaluating 1-Hexene Suppliers 

Even when sourcing mixed hexene, supplier evaluation remains an important step. 

Packaging and logistics 

Mixed hexene is commonly supplied in drums or tanker loads, depending on volume requirements and handling infrastructure. 

Quality parameters 

Buyers should review specifications such as distillation range, specific gravity, APHA colour, and GC composition. Clearly defined impurity limits help ensure consistent performance across batches. 

Handling considerations 

As a volatile and flammable hydrocarbon, mixed hexene must be stored and transported in line with standard hydrocarbon safety practices. 

These checks apply whether sourcing pure material or mixed C6 streams from 1-hexene suppliers.
