Beschreibung
Stoddard solvent is a refined petroleumdistillate derived fromthe
naphtha and kerosene carbon ranges (C7–C12) in crude oil. It is
a type of ‘white spirit,’ characterized as a clear solvent absent of
objectionable odors (hydrodesulfurized to remove hydrogen
sulfide and mercaptans). Stoddard solvent typically contains
paraffinic alkanes (saturated branched and linear), cycloalkanes
(also known as cycloparaffins), and aromatic hydrocarbons.
Paraffins (30–50%) and cycloparaffins (30–40%) tend to
predominate, with a remaining 10–20%comprised of aromatics.
The exact composition of Stoddard solvent can vary due to variations
in crude oils and the refining processes. The boiling range
of Stoddard solvent is approximately 148.8–204.4 °C.
Chemische Eigenschaften
Stoddard solvent is a refined petroleum solvent containing .65% C10 or higher hydrocarbons (mineral spirits, 85% nonane & 15% trimethylbenzene). Stoddard solvent is a colorless liquid. Kerosene-like odor
Verwenden
Stoddard solvent is used widely in dry cleaning processes,
and as a general cleaning and universal solvent.
Allgemeine Beschreibung
A clear colorless mixture with a strong odor. Insoluble in water and about the same density as water. Flash point over 100°F. Avoid exposure. Used as a solvent and to make other chemicals.
Air & Water Reaktionen
Flammable. Insoluble in water.
Reaktivit?t anzeigen
NAPHTHA: NEO-CLEAR(R) XYLENE SUBSTITUTE is incompatible with the following: Strong oxidizers .
Hazard
Fire risk. Toxic by ingestion. Eye, skin
and kidney damage; nausea; central nervous system
impairment.
Health Hazard
High concentration of vapors may cause intoxication. If liquid is swallowed, it may get into lungs by aspiration; not very irritating to skin or eyes.
Sicherheitsprofil
Mildly toxic by inhalation. A human eye irritant. Flammable liquid when exposed to heat, sparks, or flame. Explosive in the form of vapor when exposed to heat or flame. When heated to decomposition it emits acrid fumes and may explode; can react with oxidzing materials. To fight fire, use foam, CO2, dry chemical. See also n-NONANE.
m?gliche Exposition
Stoddard solvent is used as a diluent in paints, coatings, and waxes; as a paint thinner; as a drycleaning agent; as a degreaser for metal parts; as a herbicide
Carcinogenicity
Stodddard solvent was not genotoxic
in a variety of assays including Salmonella
typhimurium, a mouse lymphoma mutation
assay, rodent bone marrow cytogenic tests, and
rodent dominant lethal tests.
Environmental Fate
The hydrocarbons in Stoddard solvent vary in volatility and
water solubility. Spills of Stoddard solvent would be expected
to partition to soil, groundwater, and air. Smaller alkanes and
aromatics will likely volatilize to the air where photooxidation
can occur. Biodegradation in soil and/or water may be more
likely for the larger aliphatic and aromatic hydrocarbons,
although Stoddard solvent is unlikely to be readily biodegradable.
Although the larger hydrocarbons in Stoddard
solvent are expected to have slower elimination from biological
tissues than the smaller constituents, Stoddard solvent overall
would not be expected to bioaccumulate.
Versand/Shipping
UN1993 Flammable liquids, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, Technical Name Required. UN1268 Petroleum distillates, n.o.s. or Petroleum products, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid.
Inkompatibilit?ten
May form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Attacks some forms of plastics, rubber, and coatings.
Waste disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
