Basic Information
Product Name: Solvent naphtha (petroleum), light arom.
CAS Number: 64742-95-6
Alias: Light aromatic solvent naphtha, High Flash Aromatic Naphtha (HFAN), C9 aromatic solvent oil, Aromatic Naphtha Type 1
Composition: Complex petroleum distillate mixture, dominated by C8–C10 aromatic hydrocarbons (ethyltoluene, trimethylbenzene isomers, xylene derivatives), aromatic content ≥98%
IUPAC Description: Petroleum distillate solvent naphtha enriched with light aromatic hydrocarbons (C8–C10)
Structural Information
- Structure Type: Complex mixed aromatic hydrocarbon petroleum fraction
- Structural Features: Single benzene ring substituted with methyl/ethyl alkyl side chains; strong solvency for resins, oils, polymers; medium volatility, higher flash point than low-boiling xylene solvents
Physical & Chemical Properties
- Appearance: Colorless transparent liquid, faint aromatic hydrocarbon odor
- Density (20℃): 0.860–0.875 g/cm3
- Distillation range: 135–210 ℃ (typical commercial grade 152–178 ℃)
- Flash point: ≥42 ℃ (closed cup)
- Vapor pressure (25℃): 2.1–8.29 mmHg; vapors heavier than air, easy to accumulate at low ground
- Solubility: Insoluble in water; fully miscible with alcohols, ketones, esters, mineral oils, most resins; slight solubility in methanol
- Stability: Stable under normal sealed storage; incompatible with strong oxidants (permanganate, peroxide); volatile, vapor forms explosive mixture with air; no self-polymerization at room temperature
Synthesis & Applications
Production Method
Fractional distillation of petroleum reformate aromatic oil, cut C8–C10 light aromatic fraction, desulfurization and rectification to remove heavy components and light non-aromatic impurities.
Main Applications
- Coatings & ink industry: High boiling solvent for baking paint, alkyd resin coatings, high-grade printing ink, slow-evaporation diluent
- Pesticide industry: Emulsifier carrier solvent for EC pesticide formulations
- Industrial cleaning: Precision machinery degreasing solvent, metal surface cleaning agent
- Chemical auxiliary: Extraction solvent for hydrogen peroxide production, rubber resin dissolving agent
- Adhesive raw material: Solvent for polyurethane, acrylic adhesives
