It is also used in the production of adhesives, coatings, and sealants. Bis(2,4-di-tert-butylphenyl)phenyl phosphonite helps to prevent the degradation of polymers caused by heat, light, and oxygen exposure, thereby extending the lifespan and improving the performance of the products. Bis(2,4-di-tert-butylphenyl)phenyl phosphonite is known for its high stability and effectiveness in protecting polymers from degradation, making it a valuable additive in the manufacturing of plastic and rubber products.
Check Digit Verification of cas no
The CAS Registry Mumber 70146-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,4 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70146-21:
(7*7)+(6*0)+(5*1)+(4*4)+(3*6)+(2*2)+(1*1)=93
93 % 10 = 3
So 70146-21-3 is a valid CAS Registry Number.

STERICALLY HINDERED PHOSPHONITES

Phosphonochloridous and phosphonous esters were prepared from the reaction of phenylphosphonous dichloride with 2,4-di-tert-butylphenol, 2,6-di-tert-butyl-4-methylphenol, and 2,4,6-tri-tert-butylphenol.Various synthetic methodologies, including phase-transfer catalysis, are described and compared.Phosphonous diesters containing two different substituted-phenyl moieties were prepared from phosphonochloridous monoesters.The reaction of O-(2,6-di-tert-butyl-4-methylphenyl)-phenylphosphonochloridite with N-methyldiethanolamine, n-octyl mercaptan, and water was studied and found to give a biphosphonite, phosphonothioite and phosphinate, respectively.
