Cyclohexanone Solvent CYC Purity 99.8% Min
Formula: C₆H₁₀O

Cyclohexanone

CYC (High Purity Solvent)

Cyclohexanone is a clear, oily organic liquid with a distinctive peppermint-like odor. It is a powerful cyclic ketone solvent. It is primarily used as the precursor to Caprolactam (for Nylon 6) and Adipic Acid (for Nylon 6,6). In the industrial market, it is the #1 choice for dissolving PVC, making it the key ingredient in PVC Pipe Cements and Adhesives.

CAS Number 108-94-1
Purity 99.8% Min
Boiling Point 155.6°C

Product Overview

Cyclohexanone is a high-boiling solvent with excellent solvency for many polymers, resins, waxes, and fats. It is unique because it can dissolve difficult resins like PVC, Nitrocellulose, and Methacrylate better than most other solvents.

  • Slow Evaporation: Allows paints and inks to flow out smoothly (leveling) before drying, preventing surface defects.
  • Agrochemicals: Excellent solvent for formulating insecticides (DDT) and fungicides because it emulsifies well.
  • Nylon Synthesis: The backbone of the Nylon industry (precursor to Caprolactam).

Mechanism: "Cold Welding" with CYC

It's Not Glue, It's Chemistry

When joining PVC pipes, you don't use glue; you use "Solvent Cement." Cyclohexanone is the active ingredient.

  • Melting Action: When applied, CYC attacks the PVC plastic surface, temporarily dissolving and softening the polymer chains.
  • Fusion: When two softened pipes are pressed together, their polymer chains tangle and fuse. As the CYC evaporates, the plastic re-hardens into a single, solid piece. This bond is often stronger than the pipe itself.

Industrial Applications

PVC Cements & Adhesives

The main solvent used in CPVC and PVC pipe joining cements and cleaning fluids.

Nylon Manufacturing

Key raw material to produce Caprolactam and Adipic Acid, which make Nylon fibers.

Pesticides

Excellent solvent for dissolving active ingredients in insecticides, herbicides, and fungicides.

Printing Inks

Used in screen printing inks and PVC-based inks to improve flow and adhesion.

Pharmaceuticals

Reaction solvent for synthesis of antihistamines and other drugs.

Magnetic Tapes

Used as a solvent/coating agent in the production of magnetic audio and video tapes.

Packaging Options

Standard heavy-duty steel drums. Ideal for safe transport.

ISO Tank Containers

Bulk supply (20-24 MT) for large scale adhesive and nylon factories.

Safety & Handling Protocols

Flammable & Harmful

Cyclohexanone is a Class 3 Flammable Liquid.

  • Inhalation: Vapors are heavy and can travel. Do not inhale. Use in well-ventilated areas or fume hoods.
  • Skin Contact: Degreases skin rapidly. Wear solvent-resistant gloves. Can cause dermatitis.
  • Fire: Flash point 44°C. Keep away from sparks and open flames. Use foam/powder extinguishers.
