6-bromohexyl acetate

Описание

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.

Химические свойства

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

Использование

Stoddard solvent is used widely in dry cleaning processes, and as a general cleaning and universal solvent.

Общее описание

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.

Реакции воздуха и воды

Flammable. Insoluble in water.

Профиль реактивности

NAPHTHA: NEO-CLEAR(R) XYLENE SUBSTITUTE is incompatible with the following: Strong oxidizers .

Опасность

Fire risk. Toxic by ingestion. Eye, skin and kidney damage; nausea; central nervous system impairment.

Угроза здоровью

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.

Профиль безопасности

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.

Возможный контакт

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

Канцерогенность

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.

Экологическая судьба

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.

Несовместимости

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.

Утилизация отходов

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.
