OGSCM / TECHNICAL PROCUREMENT INTELLIGENCE

Xylene / Mixed Xylenes (C₈H₁₀)

Aromatic Solvent and BTX Feedstock for Coatings, Chemical Manufacturing and Petrochemical Processing

Xylene is not one single procurement grade. Industrial supply may mean mixed xylenes or a specific o-, m- or p-xylene isomer, and these materials are not automatically interchangeable. Buyers should define composition, purity, non-aromatics, ethylbenzene content where relevant, distillation range, water, color and downstream use before sourcing.

CHEMISTRY, MANUFACTURING CONTEXT & MATERIAL BEHAVIOUR

Xylenes are dimethylbenzene isomers within the BTX aromatics family. The source draft correctly distinguishes mixed xylene from o-, m- and p-xylene and links commercial production mainly to reformate/BTX streams. For procurement, the isomer distribution and accompanying aromatics matter because solvent-grade mixed xylene and purified petrochemical isomers serve different downstream functions.

PROCESS-ENGINEERING & GRADE-SELECTION CONSIDERATIONS

  • Define whether the RFQ is for mixed xylene or a specific isomer; CAS number alone should match that identity.
  • For solvent service, specify distillation range, density, color, water and non-aromatic/total aromatic content as required by the formulation.
  • For petrochemical feedstock, define isomer purity and relevant co-components such as ethylbenzene according to the downstream unit.
  • The source draft calls xylene 'insoluble in water'; technically it has low but finite water solubility, so 'sparingly soluble' is more accurate.
  • Storage and transfer require flammable-liquid controls, bonding/grounding, vapor management and compatible closed systems.

◎ Technical Specifications

Property Value

Formula

CAS

Mixed xylenes 1330-20-7; o-xylene 95-47-6; m-xylene 108-38-3; p-xylene 106-42-3

Appearance

106.16 g/mol

Boiling range

Isomer/mixture dependent; mixed-xylene values are not a universal single boiling point

Water solubility

Low / sparingly soluble, not literally zero

Key hazard

Flammable liquid; harmful vapor exposure requires controlled handling

Supply form from source draft

180 kg barrels or bulk

Critical grade distinction

Mixed xylenes vs individual isomer / petrochemical feedstock grade

INDUSTRIAL APPLICATION MATRIX

Paints, coatings, inks

  • Process role: Aromatic solvent / diluent
  • Critical parameters: Distillation range; solvency; water; color; evaporation profile

Adhesives & rubber processing

  • Process role: Solvent / formulation carrier
  • Critical parameters: Composition; purity; residue; compatibility

Petrochemical processing

  • Process role: BTX feedstock or isomer-specific raw material
  • Critical parameters: Isomer purity; ethylbenzene/non-aromatics; downstream specification

Printing / leather / cleaning formulations

  • Process role: Solvent function where permitted
  • Critical parameters: Grade; odor/vapor controls; formulation compatibility

QUALITY CONTROL, COA PARAMETERS & TEST FOCUS

  • Isomer / aromatic composition | Method/evidence: GC | Why it matters: Confirms mixed-xylene or isomer-specific grade
  • Distillation range | Method/evidence: ASTM/producer method | Why it matters: Volatility and solvent performance
  • Density / specific gravity | Method/evidence: Density meter | Why it matters: Receiving and composition screen
  • Water | Method/evidence: Karl Fischer | Why it matters: Process/formulation compatibility
  • Color | Method/evidence: ASTM/APHA as specified | Why it matters: Contamination/appearance control
  • Non-aromatics / ethylbenzene | Method/evidence: GC | Why it matters: Feedstock and solvent-grade qualification

STORAGE, HANDLING, COMPATIBILITY & HSE

Treat xylene as a flammable aromatic solvent. Use closed transfer where practicable, suitable ventilation, ignition-source control, bonding/grounding and PPE selected from the supplier SDS. Vapor exposure and skin contact should be controlled. Spill response must prevent entry to drains and uncontrolled soil/water release.

PACKAGING, TRANSPORT & GCC / MENA SUPPLY PLANNING

The source draft identifies 180 kg barrels and bulk supply. Final packaging should be confirmed against the offered grade, transport classification, route and receiving infrastructure. For GCC/MENA, consider heat exposure, vapor control, drum/tank compatibility, hazardous-goods documentation and unloading capability.
