68308-34-9 Usage
Description
Shale oil is a type of crude oil extracted from sedimentary shale formations by heating the shale to 425–535°C (800–1000°F). It has a specific gravity ranging from 0.9 to 1.0, which exceeds that of natural crude oil. Shale oil contains significant amounts of nitrogen, oxygen, and sulfur compounds, and consists of hydrocarbons, including isoalkenes, cycloalkenes, polycyclic aromatic hydrocarbons (PAHs), normal olefins, normal alkanes, and monocyclic aromatic compounds. The oil-bearing component of the shale is called kerogen, a bitumen-like solid material formed millions of years ago by deposition of silt and organic debris on lake beds and sea bottoms.
Uses
Used in Fuel Industry:
Shale oil is used as a raw material for producing gasoline, kerosene, gas oil, and lube oils, providing a source of energy for various applications.
Used in Chemical and Manufacturing Industries:
Shale oil is used as a starting material for producing varnishes, pitches, and mastics, which are employed as solvents and glues, and as starting materials for the printing and rubber products industries.
Used in Pharmaceutical Industry:
Sulfonated shale oils, such as Ichthyol, are used as pharmaceutical agents for the treatment of skin diseases like eczema and psoriasis, rheumatic diseases, and even for the treatment of blunt trauma. Human testing has shown that sulfonated shale oils are without significant side effects and are as effective as hydrocortisone in treating inflammatory lesions of the skin.
Flammability and Explosibility
Nonflammable
Safety Profile
Confirmed human
carcinogen with experimental carcinogenic,
neoplastigenic, and tumorigenic data. Mildly
toxic by ingestion, skin contact, and
intraperitoneal routes. A skin irritant.
Experimental reproductive effects. Mutation data reported. Flammable when exposed to
heat and flame. When heated to
decomposition it emits acrid smoke and
fumes.
Environmental Fate
Releases of shale oil components to the environment can
occur in several ways during the extraction, processing, and
transport of this material. The more volatile components of
shale oil can be released to the atmosphere especially during
the retorting process when heat is applied to the shale.
Workers at shale processing plants and, to a lesser extent,
people residing near those operations can be exposed to the
lighter volatile organic chemical components of shale oil
released into the air. Spills or other accidental releases of shale
oil and its components can threaten wildlife and adversely
impact aquatic organisms if the material reaches surface
waters. In some areas, spills of oil could reach shallow aquifers
thus affecting ground water. Soil contamination is an obvious
result of such spills as well.
Check Digit Verification of cas no
The CAS Registry Mumber 68308-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,0 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 68308-34:
(7*6)+(6*8)+(5*3)+(4*0)+(3*8)+(2*3)+(1*4)=139
139 % 10 = 9
So 68308-34-9 is a valid CAS Registry Number.
