Ethylbenzene 99.5% / 99.8% CAS No. 100-41-4 Industrial & Polymer Grade

Ethylbenzene, available in 99.5% and 99.8% concentrations, is produced via advanced alkylation technology using benzene and ethylene, followed by rigorous fractionation and purification processes. It features excellent solvency power, controlled evaporation rate, and exceptional chemical stability as a key aromatic hydrocarbon. As the essential precursor for styrene monomer production, it is widely used in the polymer industry, coatings, and chemical synthesis. Its high purity and consistent quality make it ideal for critical applications requiring precise chemical properties. Each batch is rigorously tested using GC analysis to ensure consistent quality meeting industrial and polymer-grade standards.

FAQ

What are the main differences between the 99.5% and 99.8% purity grades of Ethylbenzene?

The 99.5% grade is suitable for most industrial applications including general solvent use and chemical synthesis. The 99.8% polymer grade provides higher purity specifically engineered for styrene monomer production, with stricter control over catalyst poisons including benzene (<50 ppm vs. <500 ppm), sulfur compounds (<1 ppm vs. <5 ppm), and other impurities that affect dehydrogenation catalyst performance and styrene quality.

What specifications are critical for polymer-grade Ethylbenzene?

Polymer-grade Ethylbenzene requires strict control over impurities that affect styrene production: benzene (<50 ppm) to prevent by-product formation, toluene (<100 ppm) for consistent reactivity, diethylbenzene (<10 ppm) to avoid cross-contamination, sulfur compounds (<1 ppm) to prevent catalyst poisoning, and non-aromatic hydrocarbons (<0.1%) to maintain proper boiling characteristics. Water content must be below 100 ppm to prevent catalyst deactivation. Certificates of analysis with comprehensive impurity profiling are provided with each polymer-grade shipment.

What are the environmental considerations for Ethylbenzene handling?

Ethylbenzene is classified as hazardous to the aquatic environment (chronic toxicity). Spill prevention and containment measures must be implemented to prevent environmental release. In case of spillage, contain with non-combustible absorbent materials and dispose of as hazardous waste. Volatile organic compound (VOC) emissions should be controlled through vapor recovery systems and proper storage tank design.
