367-44-2 Usage
General Description
DIETHYL ALUMINUM FLUORIDE is a colorless liquid chemical compound that is used as a catalyst in the production of high-density polyethylene and polypropylene. It is also used as a co-catalyst in Ziegler-Natta polymerization processes. The compound is highly flammable and reactive, and should be handled with extreme caution. It is known to cause skin and eye irritation, and can also cause respiratory and digestive tract irritation if inhaled or ingested. Proper safety measures, including the use of personal protective equipment and proper ventilation, are necessary when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 367-44-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,6 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 367-44:
(5*3)+(4*6)+(3*7)+(2*4)+(1*4)=72
72 % 10 = 2
So 367-44-2 is a valid CAS Registry Number.

The structure and properties of diethylfluoroalane, (C2H5)2AlF
Laubengayer,Lengnick
, p. 503 - 507 (1966)
The unusually viscous compound diethylfluoroalane, (C2H5)2AlF, has been characterized. Cryoscopic and ebullioscopic molecular weight determinations in benzene solution indicate the existence of a tetramer. Infrared, pmr, and F19 nmr spectra support a ring structure, with an alternating aluminum-fluorine backbone for the tetramer. The compound has acceptor properties weaker than those of the other dialkylhaloalanes. No stable ether adduct could be isolated, but the identity of amine adducts and their decomposition products has been established. Pyrolytic decomposition of (C2H5)2AlF yields ethane, in contrast to the olefins which have been reported for other alkylaluminum compounds. The high viscosity of liquid (C2H5)2AlF is believed to result from extensive Al-F-Al bridging to build polymeric frameworks. Copyright 1966 by the American Chemical Society.
