Zinc, ethylphenoxy-, also known as zinc ethylphenol, is a chemical compound with the formula Zn(C6H5OCH2CH3)2. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. Zinc, ethylphenoxy- is primarily used as a catalyst in various chemical reactions, such as the polymerization of olefins and the production of polyethylene. It is also employed as a stabilizer in the manufacturing of polyvinyl chloride (PVC) to prevent the degradation of the polymer. Zinc ethylphenol is known for its high thermal stability and resistance to hydrolysis, making it a valuable component in industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 28557-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,5 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28557-01:
(7*2)+(6*8)+(5*5)+(4*5)+(3*7)+(2*0)+(1*1)=129
129 % 10 = 9
So 28557-01-9 is a valid CAS Registry Number.

KINETICS AND MECHANISM OF THE REACTIONS OF DIETHYLZINC WITH PHENOLS IN CYCLIC ETHERS

Gorecki, Piotr,Kuran, Witold

, p. 1 - 8 (1984)

Reactions of diethylzinc and phenols (phenol, 2-ethylphenol, 2-chlorophenol, 3-ethylphenol, 3-chlorophenol, 4-ethylphenol and 4-chlorophenol) have been carried out in tetrahydrofuran and 1,4-dioxane as solvents.Monomeric ethylzinc phenoxide has been found to be a product of the diethylzinc and phenol (1:1) reaction in 1,4-dioxane solution.Kinetic studies on the ethylzinc phenoxides and phenols reaction in tetrahydrofuran solution established the rate constants and the SEi mechanism of the reaction.
