Applications

Agrochemical industry: Solvent and carrier for emulsifiable concentrates (EC) and formulation auxiliaries; alkylbenzene intermediate for pesticide synthesis.
Industrial solvents: High-boiling aromatic solvent in coatings, resins, cleaning formulations, and extraction processes.
Chemical intermediate: Feedstock for alkylated aromatics, styrenic/cumene-type derivative routes, and specialty surfactants.
Distillation / process streams: Component in C9–C10 aromatic cuts and solvent recovery systems.

Manufacturing & Quality Control

🔍 Production Process: Manufactured via Friedel-Crafts alkylation of benzene with ethylene, followed by fractional distillation to achieve target isomer enrichment and purity grade.

FAQ

Q: Is this pure 1,2-isomer or a mixed diethylbenzene cut?

A: Both available. Tell us your target 1,2-content (e.g. ≥95% single isomer or mixed-isomer grade).

Q: What grade do you supply?

A: Industrial Grade and Agricultural Grade only - not pharma/food grade.

Q: Main use in agriculture?

A: Solvent/carrier for pesticide formulations and as an alkylbenzene synthesis intermediate.
