2167-55-7 Usage
General Description
Bis(4-propan-2-ylphenyl) carbonate is a chemical compound with the molecular formula C23H26O3. It is a carbonate ester and is often used as a reactive plasticizer in the production of polycarbonate resins and other polymers. bis(4-propan-2-ylphenyl) carbonate is known for its high thermal stability, which makes it suitable for use in various applications, including in the production of automotive parts, electrical components, and optical lenses. Bis(4-propan-2-ylphenyl) carbonate is flammable and may release toxic fumes when heated, so it should be handled with care and in accordance with proper safety measures.
Check Digit Verification of cas no
The CAS Registry Mumber 2167-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2167-55:
(6*2)+(5*1)+(4*6)+(3*7)+(2*5)+(1*5)=77
77 % 10 = 7
So 2167-55-7 is a valid CAS Registry Number.

Process for the autoxidation of an isopropylphenyl ester
-
, (2008/06/13)
Isopropylphenyl esters are converted to di- or trihydric phenols via a novel autoxidation of the esters at high conversion rates to the corresponding hydroperoxyisopropylphenyl esters in the presence of a catalyst combination comprising at least two members selected from the group consisting of (i) a metal phthalocyanine; (ii) a di-tertiary alkyl peroxide; and (iii) a tertiary alkyl hydroperoxide. Rearrangement of the hydroperoxyisopropylphenyl esters to the corresponding hydroxyphenyl esters and the hydrolysis of the latter compounds provides the phenols in overall yields (from the starting esters) heretofore not obtainable. Novel bis(hydroperoxyisopropylphenyl)carbonates are described which are attractive intermediates for the intermediate bisphenol carbonate or the final hydroquinone hydrolysis product.
