12075-68-2 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 12075-68-2 differently. You can refer to the following data:
1. clear colorless solution
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 olefin polymerization, aromatic hydrogenation; intermediate.

General Description

A clear yellow liquid. Slightly denser than water. Used to make other chemicals.

Air & Water Reactions

Spontaneously flammable in air (Douda 1966). Reacts violently with water forming hydrogen chloride and flammable ethane gas (Rose 1961).

Reactivity Profile

Organometallics, such as ETHYLALUMINUM SESQUICHLORIDE, are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water. A mixture of ETHYLALUMINUM SESQUICHLORIDE with carbon tetrachloride exploded when warmed to room temperature [Bretherick, 5th Ed., 1995].

Hazard

Ignites on contact with air, dangerous fire risk, reacts violently with water.

Health Hazard

Inhalation of smoke from fire causes metal-fume fever (flu-like symptoms); acid fumes irritate nose and throat. Contact with liquid, which is spontaneously flammable, causes severe burns of eyes and skin.

Safety Profile

Mixtures with carbon tetrachloride explode at room temperature. When heated to decomposition it emits toxic fumes of Cl-. See also ALUMINUM COMPOUNDS.

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 12075-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,7 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12075-68:
(7*1)+(6*2)+(5*0)+(4*7)+(3*5)+(2*6)+(1*8)=82
82 % 10 = 2
So 12075-68-2 is a valid CAS Registry Number.

Process for producing ethylene/alpha-olefin copolymer

-

, (2008/06/13)

A copolymer of ethylene and an alpha-olefin having an ethylene content of from 30 to 90 mole %, a number average molecular weight of from 300 to 30,000 and a molecular weight distribution defined by a Q value (the ratio of the weight average molecular weight to the number average molecular weight of not more than 3 and a Z value (the ratio of the maximum value of the molecular weight to the minimum value of the molecular weight when the molecular weight is measured by gel permeation chromatography) of from 15 to 200. The said copolymer can be produced by a process comprising copolymerizing ethylene with an alpha-olefin in the liquid phase in the presence of a polymerization catalyst composed of a combination of a soluble vanadium compound and an organoaluminum compound in the co-presence of hydrogen, characterized in that (a) the copolymerization is carried out in a continuous manner, (b) the concentration of the vanadium compound in the polymerization system is maintained at 0.3 to 30 millimoles/liter, and (c) the vanadium compound is supplied to the polymerization system as a solution in a polymerization medium in a concentration which is 1 to 5 times the concentration of the vanadium compound in the liquid phase. This compound is useful as a synthetic lubricant oil, a fuel oil additive and a lubricant oil additive.

Process for preparing organosilanes

-

, (2008/06/13)

An improved process for converting an organosilane which comprises reacting at least one silane (A) having the formula with at least one silane (B) which differs from silane (A) and has the formula in the presence of an organoaluminum compound having the formula and at least one silane (C) having the formula and from 0.1 to 5 percent by weight based on the weight of silanes (A), (B) and (C) of a hydrogen halide, in which R is a hydrocarbon radical having from 1 to 10 carbon atoms and is free of aliphatic unsaturation, R1 is an alkyl radical having from 1 to 4 carbon atoms, Y is selected from the group consisting of halogen, hydrogen or hydrocarbon radicals having from 1 to 10 carbon atoms which are bonded to the aluminum via oxygen and are free of aliphatic unsaturation, a is 2, 3 or 4, b is 0, 1, 2 or 3 and c is 1, 2 or 3 and the sum of b+c cannot exceed 4.
