Ortho Xylene

OX Isomer (Virgin Grade)

Ortho Xylene (OX) is the second most important commercial isomer of xylene. It is a clear, colorless liquid produced by the distillation of Mixed Xylenes. Its primary and most vital application is as the raw material for manufacturing Phthalic Anhydride (PAN), which is essential for making PVC plasticizers.

CAS Number 95-47-6
Purity 99.0% Min
Boiling Point 144°C

Product Overview

In the "Xylene Family," Ortho Xylene is the heavy brother. It has the highest boiling point (144°C) compared to Meta and Para isomers. This property allows it to be separated from mixed xylene streams by distillation. Ruvon supplies high-purity OX suitable for chemical synthesis and specialized solvent applications.

  • Consistent Quality: Low non-aromatic content ensures stable reactions during PAN production.
  • High Flash Point: Flash point of ~32°C makes it slightly safer to handle than Toluene or Benzene.
  • Solvency: Excellent solvent for bactericides, herbicides, and lube oil additives.

Mechanism: The "Plasticizer Chain"

From Liquid to Flexible Leather?

Ortho Xylene is the starting point for making PVC soft (like artificial leather or cables). Here is the chain:

  • Step 1 (Oxidation): Ortho Xylene is oxidized with air to form white flakes called Phthalic Anhydride (PAN).
  • Step 2 (Reaction): PAN reacts with alcohols (like 2-EH) to form DOP/DINP (Plasticizers).
  • Step 3 (Softening): This Plasticizer is mixed with rigid PVC powder. The result is flexible PVC used in wires, shoes, and hoses. Without Ortho Xylene, the flexible PVC industry would stop.

Industrial Applications

Phthalic Anhydride (PAN)

The single largest use (~90%). Precursor to plasticizers and alkyd resins.

Alkyd Resins

Used in the production of alkyd resins for paints, enamels, and varnishes.

Agrochemicals

Solvent carrier for herbicides and pesticides due to high solvency.

Pigments & Dyes

Intermediate in the synthesis of Phthalocyanine dyes (Blue/Green pigments).

Lube Additives

Used to manufacture specialized additives for lubricating oils.

Pharmaceuticals

Solvent and intermediate for vitamin and antibiotic synthesis.

Packaging Options

Standard heavy-duty steel drums. Ideal for distribution.

Road Tanker / ISO Tank

Bulk supply (18-20 MT) for PAN manufacturers and large paint plants.

Safety & Handling Protocols

Flammable Liquid

Ortho Xylene is a Class 3 Flammable Liquid.

  • Ventilation: Vapors are heavier than air. Ensure good ventilation at floor level to prevent accumulation.
  • Skin: Can cause irritation and dryness. Wear Nitrile gloves.
  • Storage: Store in a cool, dry place away from oxidizers and ignition sources.
