4221-80-1 Usage
Description
2,4-Di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate, also known as UV 120, is a white crystalline powder that is widely used as a stabilizer in the polymer industry. It is an effective additive for preventing the degradation of polymers, particularly pigmented ones, where the pigment can contribute to the breakdown of the polymer. UV 120 does not absorb visible light, which means it does not impart any initial color to the substrate or polymer, making it an ideal choice for maintaining the original appearance of the material.
Uses
Used in Polymer Industry:
2,4-Di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate is used as a stabilizer for [application reason] to prevent the degradation of pigmented polymers, especially in cases where the pigment itself can promote polymer degradation. Its non-absorption of visible light ensures that it does not alter the initial color of the substrate or polymer, preserving the material's original appearance.
Used in Pigmented Polymers:
In the context of pigmented polymers, 2,4-Di-tert-butylphenyl 3,5-di-tert-butyl-4-hydroxybenzoate is used as a protective agent for [application reason] to safeguard the polymer from degradation caused by the pigment. Its ability to not affect the visible light spectrum makes it a preferred choice for maintaining the color integrity of the pigmented polymers.

Check Digit Verification of cas no
The CAS Registry Mumber 4221-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4221-80:
(6*4)+(5*2)+(4*2)+(3*1)+(2*8)+(1*0)=61
61 % 10 = 1
So 4221-80-1 is a valid CAS Registry Number.

Method for preparing phenyl benzoate ultraviolet absorber through ester exchange
-
Paragraph 0070-0071, (2019/11/20)
The invention provides a method for preparing a phenyl benzoate ultraviolet absorber through ester exchange. The method comprises the steps that at least one hindered phenol in the formula I reacts with alkali at 100-140 DEG C to obtain hindered phenol salt, then the hindered phenol salt reacts with at least one benzoate compound of the formula II at 110-195 DEG C, and the absorber is obtained. Accordingly, the disadvantages of being high in production cost, large in industrial waste water and the like caused by the traditional acyl chloride process are avoided; the disadvantages of poor product selectivity caused by an esterification method, low atomic utilization rate caused by an acid anhydride method and the like are avoided; in addition, the method has the advantages of being low in production cost, easy to operate and implement, high in reaction speed, high in single yield of products and capable of recycling and mechanically applying unreacted raw materials, so that the method is more suitable for industrial production.
