Phenol, 2,2'-(1,2-ethanediyl)bis[6-(1,1-dimethylethyl)-4-methyl-] is a complex organic compound with the chemical formula C21H32O2. It is a derivative of phenol, characterized by two phenol units connected through an ethylene bridge (1,2-ethanediyl). Each phenol unit features a methyl group (CH3) at the 4-position and a tert-butyl group (1,1-dimethylethyl) at the 6-position, which contributes to the compound's stability and lipophilic properties. This chemical is known for its antioxidant properties and is commonly used as a stabilizer in various industrial applications, particularly in the polymer and plastic industries, to prevent degradation caused by heat, light, and oxygen exposure.

6766-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6766-56-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,6 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6766-56:
(6*6)+(5*7)+(4*6)+(3*6)+(2*5)+(1*6)=129
129 % 10 = 9
So 6766-56-9 is a valid CAS Registry Number.

Method of producing 2,2 '-methylenebis(4,6-dialkylphenols)

-

, (2008/06/13)

A method of producing 2,2'-methylenebis(4,6-dialkylphenols) residing in that 2,4-dialkylphenols interact with acetals in the presence of an acid catalyst at a temperature from 30° C to 140° C with the formation of a reaction mixture containing the desired product and with subsequent separation of the desired product from said mixture, the starting reagents being taken in amounts of 1 mole of 2,4-dialkylphenol per 1-10 moles of acetal. The method is technologically simple and accomplished without the formation of waste water.
