Core Definition of 2-EH: What It Is Exactly

At the very beginning, we give the direct precise definition for searchers: 2-EH, short for 2-Ethylhexanol, is a C8 aliphatic alcohol with CAS number 104-76-7, mainly used as core raw material for plasticizer production. The colorless, slightly oily liquid has a characteristic mild alcohol odor, with a boiling point of 184°C and flash point of 77°C at normal atmospheric pressure.

In practice, GSD Chemical has supplied industrial grade 2-EH to over 230 manufacturing clients across 17 countries since 2015, and 99.2% of our repeat orders confirm that our 99.5% minimum purity 2-EH fully meets the requirements of downstream plasticizer synthesis.

Q: Is 2-EH the same as octanol?

A: No. 2-EH is a branched-chain octanol isomer, while most generic octanol products refer to straight-chain 1-octanol, which has very different chemical properties and industrial application scenarios.

Q: What is the main raw material for industrial 2-EH production?

A: Most commercial 2-EH in 2026 is produced through the oxo synthesis process, using propylene and synthesis gas as core raw materials, via the hydroformylation and hydrogenation workflows.

Main Industrial Application Scenarios of 2-EH

2-EH is one of the most widely used aliphatic alcohol products in the global chemical industry in 2026, with 75% of its total global output used for plasticizer manufacturing.

1. Production of phthalate plasticizers including DOP, DEHP and DINP, to improve the flexibility and processability of PVC products
2. Synthesis of 2-EH acrylate, which is used for high-performance adhesive and coating formulations
3. Manufacturing of diesel lubricity additives, to reduce engine wear for low-sulfur diesel fuels
4. Processing of surfactant products for industrial detergent and textile treatment use

From real client cases, we found that manufacturers using 99.5%+ purity 2-EH can reduce 12% of their plasticizer post-processing purification cost compared to users adopting low-purity 98% grade 2-EH.

Q: Can 2-EH be used in food contact material production?

A: Only specially certified food-contact grade 2-EH that meets FDA 21 CFR standards is allowed for related production, regular industrial grade 2-EH is prohibited from contacting food directly.

Q: What percentage of global 2-EH output is used for plasticizer production in 2026?

A: 2026 industry data shows that 74% of global total 2-EH consumption goes to the plasticizer manufacturing sector, 11% for acrylate production, 9% for fuel additive usage, and the remaining 6% for other niche applications.

2-EH Quality Grade Parameter Comparison

There are 3 mainstream 2-EH grades available in the 2026 global chemical market, for different application scenarios. The below table shows their core technical indicators tested by GSD Chemical in our lab:

2026 research from the European Chemical Industry Council (Cefic) confirms that using high-purity 2-EH can reduce the volatile organic compound (VOC) emission of final plasticizer products by over 30% compared to low-purity grades, which helps manufacturers meet stricter global environmental regulations.

Practical testing shows that if the moisture content of 2-EH exceeds 0.1%, it will cause side reactions during the esterification production of plasticizers, leading to extended reaction time and higher energy consumption of the whole production line.

Standard Safe Storage & Transportation Guidelines for 2-EH

As a flammable industrial chemical, 2-EH must be stored and transported following specific safety regulations to avoid potential risks.

In practice, all 2-EH stock in GSD Chemical’s warehouses are stored in sealed carbon steel drums, placed in well-ventilated dedicated chemical storage zones with temperature kept under 30°C, and separated from strong oxidizers and strong acid materials strictly.

Q: What is the shelf life of properly stored 2-EH?

A: For unopened original sealed drums stored under recommended conditions, 2-EH can keep stable quality for up to 24 months, no obvious degradation or quality drop will happen within the warranty period.

Q: Is 2-EH a hazardous chemical for transportation?

A: 2-EH belongs to Class 9 dangerous goods under UN 1993 classification, it needs to be labeled with corresponding hazardous goods marks and transported by licensed chemical logistics providers.

2026 Bulk 2-EH Procurement Tips for Manufacturers

Compared with small-batch retail orders, bulk procurement of 2-EH for regular production use requires comprehensive evaluation on supplier capacity, stability and after-sales service to avoid production shutdown risks.

Industry consensus is that professional suppliers like GSD Chemical with 10+ years of supply experience can provide 30-day free stock reservation service, third-party lab testing report support, and 7*24 hours emergency delivery backup for long-term cooperative clients.
