Solvent Degreaser
1. Basic Information
Full chemical name：Naphtha (petroleum), hydrotreated light
Synonyms：Hydrotreated light naphtha, Special boiling point spirit (SBP), Low-aromatic fast-drying degreasing solvent, 40–70 petroleum ether
EINECS：265-151-9
Category：UVCB complex aliphatic hydrocarbon mixture (no fixed single molecular formula), industrial fast-evaporating degreasing cleaning solvent, laboratory extraction solvent
Main composition：C4～C11 saturated alkanes, cycloalkanes, ultra-low aromatic hydrocarbons, desulfurized via hydrogenation refining
2. Physical & Chemical Properties
Physical Properties
- Appearance：Colorless transparent flowing liquid
- Odor：Mild light petroleum hydrocarbon odor, low odor after deep hydrogenation
- Solubility：Miscible with ethanol, acetone, toluene, dichloromethane; completely insoluble in water
- Boiling range：40～70 ℃ (standard 40/70 grade)
- Density (20 ℃)：0.715–0.720 g/mL
- Flash point：＜-30 ℃, extremely flammable
- Vapor pressure (20 ℃)：60 hPa, highly volatile, fast drying with almost no residual film
- Hygroscopy：Non-hygroscopic
- Aqueous property：Neutral oily mixture, no hydrolysis in water
Chemical Properties
- Production origin：Petroleum light fraction catalytic hydrogenation treatment, removes sulfur, nitrogen, aromatic impurities, stable storage, no yellowing
- Dissolving performance：Strong dissolving power for mineral oil, cutting oil, grease, wax, release agent, low-polarity resin
- Thermal stability：Stable at room temperature; above 180 ℃ thermal cracking generates flammable hydrocarbon vapor
- Oxidation resistance：Low unsaturated hydrocarbon content, not easy to oxidize and form gum during long-term sealed storage
- Compatibility：Compatible with all non-polar & weak polar organic solvents; incompatible with strong oxidants (concentrated nitric acid, hydrogen peroxide)
3. Main Application Fields
1. Industrial Metal Degreasing (Core Application)
Precision hardware, electronic parts, aluminum alloy, copper parts ultrasonic cleaning; remove stamping oil, drawing grease, cutting fluid, surface release agent, fast air-dry without watermarks
2. Laboratory Extraction & Chromatography

Safety Warning
Extremely flammable liquid & vapor, vapor forms explosive mixture with air at room temperature.
- Health hazard：Vapor strongly irritates eyes, nose and respiratory tract; long-term skin contact causes degreasing, dryness and dermatitis; swallowing enters lungs easily to cause fatal chemical pneumonia.
- Operation requirement：All operations in fully ventilated explosion-proof fume hood, wear organic vapor respirator, nitrile thick gloves, splash-proof goggles; all equipment grounded to eliminate static electricity, no open flame, smoking or spark sources.
- Fire fighting：Only dry powder, CO? fire extinguisher available; water cannot extinguish fire and will spread flammable liquid.
- Waste disposal：Recycle waste solvent via rectification; residual waste classified as flammable organic hazardous waste, handled by licensed professional institutions, prohibited direct discharge.
