o-Xylene Supply for Industrial Applications
Aure Chemical works with qualified Chinese producers and supply partners to evaluate o-Xylene requirements for international industrial buyers. o-Xylene, also known as ortho-Xylene or 1,2-dimethylbenzene, is a single xylene isomer primarily used as a feedstock for phthalic anhydride production and in selected industrial solvent systems.
Product suitability should be evaluated according to the required assay, residual isomer profile, ethylbenzene, water, color, nonvolatile residue and other application-specific parameters. The applicable source, specification, batch documentation, packaging and current availability should be confirmed for each inquiry.
Buyers comparing o-Xylene with other xylene isomers should identify the exact product and CAS number. o-Xylene CAS 95-47-6 is not interchangeable with m-Xylene, p-Xylene or mixed xylenes without process-specific technical review.
Basic Information of o-Xylene
o-Xylene is the ortho isomer of dimethylbenzene, with two methyl groups located at the 1,2-positions of the benzene ring.

o-Xylene Specification and Quality Review
A professional o-Xylene inquiry should include more than a general purity request. The relevant specification depends on the intended process, approved feedstock profile and customer quality requirements.
Parameters that may be reviewed include:
o-Xylene assay: The required single-isomer content should be stated together with the analytical and reporting basis where necessary.
Residual xylene isomers: Limits for m-Xylene and p-Xylene may be important for single-isomer applications.
Ethylbenzene and other aromatic components: These may affect oxidation, purification, solvent performance or customer qualification.
Water and appearance: Moisture, color and visible contamination requirements should be agreed before order placement.
Process-sensitive impurities: Sulfur, nonvolatile residue or other trace components may require review depending on the application.
Analytical methods: Gas-chromatographic area percentage, mass percentage and other reporting bases should not be treated as automatically equivalent.
A representative COA may support preliminary evaluation, but it does not report results for the future shipment batch. The batch COA should be reviewed against the specification agreed in the quotation, contract or purchase order.
Principal Applications of o-Xylene
The two principal industrial uses of o-Xylene are phthalic anhydride production and selected solvent applications. Suitability for either use depends on the exact grade and buyer specification.
Phthalic Anhydride Feedstock: o-Xylene is oxidized to produce phthalic anhydride, an intermediate used in plasticizer, alkyd-resin, unsaturated-polyester-resin and other chemical value chains.
Industrial Solvent: o-Xylene may be used in selected coatings, paints, inks, adhesives and process systems where its solvency and evaporation characteristics meet the formulation requirements.
Organic Synthesis: It may also serve as an aromatic starting material or process solvent in application-specific chemical manufacturing.
o-Xylene for Phthalic Anhydride Production
Phthalic anhydride production is the principal industrial pathway for o-Xylene. Feedstock evaluation may include o-Xylene assay, residual isomers, ethylbenzene, water, color, nonvolatile residue and other process-sensitive components.
The effect of an impurity depends on the oxidation technology, catalyst system, purification design and buyer-specific operating requirements. A high headline purity does not by itself establish process suitability.
Buyers evaluating this application may review o-Xylene for phthalic anhydride production for additional information about the value chain, feedstock qualification and procurement considerations.
o-Xylene as an Industrial Solvent
In solvent applications, buyers may evaluate solvency, evaporation behavior, odor, appearance, color, residue, moisture and compatibility with the formulation. o-Xylene should not automatically be substituted for mixed xylenes, m-Xylene, p-Xylene or another aromatic solvent without formulation and process review.
Suitability also depends on occupational exposure controls, emissions requirements, customer specifications and destination regulations. Further context is available in o-Xylene industrial solvent applications.
Packaging and Bulk Supply Options
Packaging and transportation should be evaluated according to the required quantity, source capability, destination, transport route, applicable regulations and receiving-site infrastructure.
Possible arrangements may include:
Approved drums: May be considered for smaller, trial or qualification quantities where the source and carrier permit.
Approved IBCs: May be evaluated where package approval, material compatibility, regulations and consignee capability allow their use.
Road tanker: May be considered for domestic, regional or port-transfer movements subject to tank acceptance and local requirements.
ISO tank container: May be evaluated for international bulk-liquid transportation according to tank compatibility, cleanliness, previous cargo, carrier acceptance and receiving capability.
No universal package size or ISO tank loading quantity applies to every shipment. Tank design, permitted filling conditions, product density, route restrictions, gross-weight limits and operator approval must be reviewed for the individual project.
Buyers may provide their own ISO tank or request evaluation of a supplier-arranged tank. Tank ownership, leasing, cleaning, local movement, international freight, destination discharge, detention, demurrage and return responsibilities should be agreed separately from the Incoterm.
Additional guidance is available in bulk xylene packaging and ISO tank transportation.
Storage, Handling and Safety
o-Xylene is a volatile and flammable aromatic liquid. Storage and handling should follow the current SDS, applicable regulations, approved equipment design and site-specific EHS procedures.
Ignition Control: Keep the product away from heat, sparks, flames and other ignition sources according to the approved site controls.
Static Electricity: Bonding, grounding and suitable transfer equipment may be required during loading, unloading and internal transfer.
Ventilation and Vapor Management: Suitable ventilation and closed-transfer arrangements should be evaluated according to the facility and operation.
Compatible Equipment: Tanks, pumps, hoses, seals, gaskets and fittings should be reviewed for chemical and operational compatibility.
Personal Protection: PPE requirements should be determined from the current SDS, exposure assessment and site procedure.
Spill and Emergency Planning: Facilities should maintain approved response procedures and trained personnel appropriate to the quantity and operation.
Hazard statements, pictograms and transport details can vary according to the applicable regulatory framework and SDS version. The current SDS issued or provided for the proposed source should take precedence over generalized website summaries.
