Paraffin Wax

CAS Numbers: 8002-74-2 / 308069-08-1

Molecular Formula: C₂₁H₂₇NO₃ (representative isomer)

EC Number: 232-315-6 F

orm: Solid or liquid wax, white to off-white

Origin: By-product of base oil refining in petroleum refineries

Production Process

Paraffin wax is derived from slack wax—a mixture of oil and wax obtained during the refining of lubricating oils. The production involves:

• Dewaxing: Oil is removed via crystallization using solvents like ketones

• Filtration: Separation into solid (wax + solvent) and liquid (oil + solvent) streams

• Distillation: Solvent recovery yields two products:

  • Product Wax (Press Wax)

  • Foots Oil

• Refining Grades:

  • Semi-refined: Moderate oil content

  • Fully refined: <0.5% oil, high purity

• Optional Treatments: Bleaching, deodorizing, blending for desired melt point and penetration

Classification

Paraffinic products are divided into two main categories:
