12542-85-7 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 12542-85-7 differently. You can refer to the following data:
1. Colorless liquid at 25C.
2. The aluminum alkyl halides are flammable, reactive, and may be spontaneously combustible in air. They are colorless to yellow liquids. Ethylaluminum dichloride:(563-43-9):
Uses
Catalyst for polymerization of olefins, catalyst
for hydrogenation of aromatics.
Hazard
Ignites spontaneously in air, reacts violently
with water, keep out of contact with air and moisture.
Safety Profile
A flammable liquid.
Danger from spontaneous combustion.
When heated to decomposition it emits
toxic fumes of Cl-.
Potential Exposure
These materials are used as components of olefin polymerization catalysts. The reader is referred to the entry on “Aluminum alkyls” for additional information on this entry. The aluminum alkyl halides parallel very closely the aluminum alkyls
Shipping
UN3052 Spontaneously combustible. Water reactive releasing large quantities of toxic and deadly hydrogen gas. (Note: this number does not appear in the 49/CFR HazMat tables)
Incompatibilities
The aluminum alkyl halides are strong reducing agents; they react—possibly violently—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. These chemicals react violently with nitromethaneEthylaluminum sesquichloride reacts explosively with carbon tetrachloride at room temperature. This chemical reacts violently with water, forming corrosive hydrogen chloride and flammable ethane gas. Diethylaluminum chloride may form an explosive product with chlorine azide.
Check Digit Verification of cas no
The CAS Registry Mumber 12542-85-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,5,4 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12542-85:
(7*1)+(6*2)+(5*5)+(4*4)+(3*2)+(2*8)+(1*5)=87
87 % 10 = 7
So 12542-85-7 is a valid CAS Registry Number.
