Solvent oil is one of the main separation products of petroleum. It is an important organic chemical raw material and basic oil for industrial production. Isohexane belongs to alkane solvent oil. After hydrogenation process, isohexane has the characteristics of low aromatics and low sulfur. Isohexane is purified and refined on the basis of n-hexane. The content of n-hexane contained in it is very small, and even basically does not exist.
In a sense, it is a kind of green environmental protection solvent, which is mainly used to clean precision instruments, such as wire plate, mobile phone and other electronic products. As the “Apple poisoning gate” incident broke out and environmental awareness increased, isohexane began to shine. At the same time, isohexane can also replace white oil. Therefore, it is gradually popularized in the cleaning industry.
Isohexane, English name isohexane 2-METHYLPENTANE, CAS No. 107-83-5, specific gravity 0.66, boiling point (℃) 62.0, flash point (℃) – 20, is used as pharmaceutical raw materials, solvents for adhesives and cleaners, coatings and ink solvents, polymerization solvents, and is a substitute for n-hexane.

Many people don’t know much about isohexane.
In fact, isohexane is a general term, a mixture,
It is mainly composed of the following four components
2-METHYLPENTANE
3-methyl pentane
2,2-dimethylbutane
2,3-dimethylbutane.
As a new solvent, isohexane has excellent cleaning ability in cleaning.
Suitable for oil extraction, leaching and extraction solvents, essential oil diluents,
Precision instrument (circuit board, electronic) cleaning agent, can also be used as low adhesive and aerosol.
In practical production application, it can be used to replace white oil, n-hexane and plastering water.
It can largely reduce the impact of white oil and n-hexane cleaner.

White electric oil substitute, wiping water substitute, n-hexane substitute, low cleaning agent – isohexane.
Isohexane is a C6 isomer, mainly composed of 2-METHYLPENTANE and 3-methylpentane. The product is colorless, tasteless, volatile, insoluble in water and soluble in ethanol, acetone and organic solvents.
It has the characteristics of asexual, low sulfur, low aromatics, low olefins, good solubility and good safety.
It is widely used in oil industry, aerosol industry, toy industry, coating industry and electronic industry. It is mainly used as oil extraction solvent, agent-free solvent, low adhesive solvent and aerosol solvent,
As a cleaning agent for precision instruments, electronics and footwear industry, isohexane has the advantages of high safety.
Our main products are isohexane, cyclohexane, methylcyclohexane, n-heptane, n-hexane, cyclohexane,
Isooctane,, DMF, DC, tetrahydrofuran, methyl tert butyl ether and other solvents.
Isohexane — instead of white electric oil.
Why replace white oil, because n-hexane is identified by the occupational disease center and is suspected to cause leukemia. So now the use of white oil is less and less.
What are the substitutes on the market and what are their characteristics?
White oil is mainly used for cleaning because of its ability to dissolve oil and volatilize quickly, and its price is relatively low. It is widely used in industrial production and belongs to low chain alkanes. The substitutes are also mainly low chain alkanes, such as isohexane and n-heptane. Alkanes with more carbon chains can also be cleaned, but their drying time is too long and are only used for metal cleaning (such as D40)
With the current purification technology of isohexane, the content of n-hexane contained in it is very small. Most of the so-called environmental cleaning agents on the market are this ingredient. In addition, compared with isohexane, n-heptane has less odor, slightly slower volatilization rate and less n-hexane content.
In addition to a small amount of nonflammable cleaning agent, 141b, dichloromethane and tetrachloroethylene can be used as the main components.
Most of them are mainly low chain alkanes, isohexane and n-heptane, or a small amount of mixed alkanes.
I hope it can be helpful for users who need to replace white electric oil!
