Tris(p-tert-pentylphenyl) phosphite, also known as TPPP or 1,1,1-tri(p-tert-pentylphenyl)phosphite, is a phosphorus-based organophosphorus compound with the chemical formula C30H45O3P. It is a colorless, crystalline solid that is widely used as an antioxidant and stabilizer in various industrial applications, particularly in the production of polyolefins such as polyethylene and polypropylene. TPPP is effective in preventing the degradation of these polymers caused by heat, light, and oxygen exposure, thereby extending their service life and maintaining their physical properties. The compound's stability and effectiveness are attributed to its bulky p-tert-pentylphenyl groups, which provide steric hindrance and protect the phosphite moiety from unwanted reactions.

864-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 864-56-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 864-56:
(5*8)+(4*6)+(3*4)+(2*5)+(1*6)=92
92 % 10 = 2
So 864-56-2 is a valid CAS Registry Number.

SOLID ALKYLARYL PHOSPHITE COMPOSITIONS AND METHODS FOR MANUFACTURING SAME

-

Page/Page column 38, (2011/02/24)

The invention is directed to various alkylaryl phosphite compositions that ideally are suitable for use as secondary antioxidants in polymers. In one aspect, the phosphite composition comprises a tris(dialkylaryl)phosphite in an amount from 20 to 93 weight percent; and at least one of: a bis(dialkylaryl)monoalkylaryl phosphite; a bis(monoalkylaryl)dialkylaryl phosphite; and a tris(monoalkylaryl) phosphite. The inventive phosphite composition is a solid at ambient conditions. The invention also relates to alkylate compositions and processes for forming such alkylate compositions and such phosphite compositions.
