12035-72-2 Usage
Uses
Used in Petroleum Refining Industry:
NICKEL SULFIDE -150 MESH 99.7% is used as a catalyst for refining crude oil that contains a considerable amount of sulfur. Its catalytic properties help in the efficient removal of sulfur impurities, improving the quality of the refined oil products.
Used in Medical Research:
NICKEL SULFIDE -150 MESH 99.7% has been implanted in mice to induce the growth of malignant fibrous histiocytomas. This application is utilized in the field of medical research to study the mechanisms of tumor growth and to develop potential therapeutic strategies for cancer treatment.
Production Methods
Nickel subsulfide can be prepared by a direct reaction
between nickel and sulfur at a temperature over 300C.
This process makes it possible to prepare the purest preparation
in the form of a brittle melt or monocrystals.
The largest industrial source of nickel subsulfide is the
metallurgic process of nickel matte smelting. Nickel
matte consists of nickel subsulfide and some quantities
of iron and copper sulfides. It is an intermediate product
in nickel metallurgy regardless of the type of the processed
ores.
Air & Water Reactions
NICKEL SULFIDE -150 MESH 99.7% is sensitive to prolonged exposure to air. Insoluble in water.
Reactivity Profile
Inorganic sulfides, such as NICKEL SULFIDE -150 MESH 99.7%, are generally basic and therefore incompatible with acids. Many of these compounds are reducing agents and therefore react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides. Simple salts of sulfides (such as sodium, potassium, and ammonium sulfide) react vigorously with acids to release hydrogen sulfide gas.
Fire Hazard
Flash point data for NICKEL SULFIDE -150 MESH 99.7% are not available. NICKEL SULFIDE -150 MESH 99.7% is probably combustible.
Flammability and Explosibility
Nonflammable
Safety Profile
Confirmed carcinogen
with experimental carcinogenic,
neoplastigenic, tumorigenic, and teratogenic
data. Poison by intraperitoneal and
intratracheal routes. An experimental
teratogen. Other experimental reproductive
effects. Human mutation data reported.
When heated to decomposition it emits toxic fumes of SOx. See also NICKEL
COhlPOUNDS and SULFIDES.
Check Digit Verification of cas no
The CAS Registry Mumber 12035-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12035-72:
(7*1)+(6*2)+(5*0)+(4*3)+(3*5)+(2*7)+(1*2)=62
62 % 10 = 2
So 12035-72-2 is a valid CAS Registry Number.
