1,4-Diethylbenzene, identified by its CAS number 105-05-5, is an organic compound with significant industrial utility. As a colorlessly transparent liquid, its physical and chemical properties make it particularly valuable in specific chemical processes, most notably as a desorbent for the adsorption and separation of p-xylene. Understanding these properties is crucial for R&D scientists and product formulators looking to leverage this chemical intermediate.

Physical and Chemical Properties of 1,4-Diethylbenzene

The compound is characterized by its clear, transparent liquid appearance. With a molecular formula of C10H14 and a molecular weight of 134.22, it possesses a density of approximately 0.862 g/mL at 25°C and a boiling point around 183.7°C. Its low water solubility, coupled with good solubility in organic solvents like ethanol and benzene, dictates its behavior in various mixtures. The flash point of 1,4-Diethylbenzene is around 56°C, classifying it as a flammable liquid, which necessitates careful handling and storage in well-ventilated areas, away from ignition sources. Its chemical structure, featuring an aromatic benzene ring with two ethyl groups in the para position, is key to its reactivity and application.

Primary Industrial Application: p-Xylene Separation

The most prominent use of 1,4-Diethylbenzene is as a desorbent in the selective adsorption of p-xylene. In petrochemical refineries, processes like the Parex process employ adsorbents to selectively capture p-xylene from a mixture of xylene isomers. The 1,4-Diethylbenzene is then used to desorb the captured p-xylene, allowing for its efficient recovery and purification. This application highlights the critical role of this chemical in producing high-purity p-xylene, a precursor for PTA and PET production. For companies engaged in these processes, securing a reliable 1,4-Diethylbenzene supplier that guarantees high purity (≥99%) is essential for optimizing separation efficiency and ensuring product quality. When you buy 1,4-Diethylbenzene for this purpose, ensure the supplier meets stringent quality standards.

1,4-Diethylbenzene as a Chemical Intermediate

Beyond its role in p-xylene separation, 1,4-Diethylbenzene also functions as a versatile intermediate in organic synthesis. Its aromatic structure and reactive ethyl groups can be modified or used as building blocks in the synthesis of various specialty chemicals, including pharmaceuticals, agrochemicals, and advanced materials. As a chemical intermediate manufacturer, we understand the need for precise specifications and consistent quality for these downstream applications. Researchers and chemists looking for a reliable source to buy 1,4-Diethylbenzene for synthesis will find our high-purity grades suitable for complex reactions.

Purchasing Considerations: Finding a Trusted Manufacturer

When seeking to buy 1,4-Diethylbenzene CAS 105-05-5, it is vital to partner with a reputable manufacturer.
