6,6,6',6'-Tetramethyl-bicyclohexyl-3,3'-dione, also known as 4,4'-isopropylidene diphenol (IPPD), is a chemical compound with the molecular formula C18H22O2. It is a white crystalline solid that is widely used as an antioxidant in the rubber and plastics industry. IPPD is effective in preventing the oxidation and degradation of polymers, thereby extending their service life and maintaining their physical properties. It is particularly useful in applications where resistance to heat, oxygen, and ozone is required, such as in tires, hoses, and various types of rubber goods. The compound is also known for its low volatility and non-staining properties, which make it a preferred choice in many industrial applications.

5020-04-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5020-04-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5020-04:
(6*5)+(5*0)+(4*2)+(3*0)+(2*0)+(1*4)=42
42 % 10 = 2
So 5020-04-2 is a valid CAS Registry Number.

Influence of the Water Content of the Solvent on the Product Distribution in the Electrohydrodimerization of 2-Cyclohexenones

Tissot, Paul,Surbeck, Jean-Paul,Guelacar, Fazil O.,Margaretha, Paul

, p. 1570 - 1574 (1981)

The product distribution of compounds 2, 3 and 4 formed in the electrohydrodimerization (EHD) of 1 was determined as function of the water content of the solvent (CH3CN).The presence of water favours the formation of the glycols 4 and reduces the relative amounts of 1,6-diketones 2 and hydroxyketones 3, as determined by GC./MS.-analysis.
