5334-11-2 Usage
Uses
Used in Textile Industry:
Triphenylethenyl benzoate is used as a whitening agent for fabrics to enhance their brightness and whiteness. It does so by absorbing ultraviolet light and emitting blue light, which counteracts the yellowish tinge that fabrics can develop over time, thereby maintaining their fresh and clean appearance.
Used in Plastics Manufacturing:
In the plastics industry, triphenylethenyl benzoate is used as an additive to improve the optical properties of plastic materials. By absorbing ultraviolet light and emitting blue light, it helps to reduce the yellowing effect that can occur in plastics, ensuring a more consistent and aesthetically pleasing color.
Used in Coatings Production:
Triphenylethenyl benzoate is utilized as a component in coatings to enhance their color and brightness. Its ability to absorb ultraviolet light and emit blue light helps in maintaining the vibrancy and whiteness of coated surfaces, which is particularly important for coatings used in exterior applications where they are exposed to sunlight.
Used in Paper Manufacturing:
In the paper industry, triphenylethenyl benzoate is employed to improve the whiteness and brightness of paper products. Its fluorescent properties help to neutralize any yellowish discoloration, resulting in a cleaner and more visually appealing final product.
It is important to handle and store triphenylethenyl benzoate properly to minimize any potential risks associated with its use, ensuring that its benefits are maximized while maintaining safety standards in all applications.
Check Digit Verification of cas no
The CAS Registry Mumber 5334-11-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5334-11:
(6*5)+(5*3)+(4*3)+(3*4)+(2*1)+(1*1)=72
72 % 10 = 2
So 5334-11-2 is a valid CAS Registry Number.

REACTION OF DILITHIUM BENZOPHENONE, DILITHIUM 9-FLUORENONE AND THE LITHIUM SALT OF BENZOPHENONE KETYL WITH CHLORIDES AND ANHYDRIDES OF CARBOXYLIC ACIDS
Honzl, J.,Metalova, M.
, p. 297 - 306 (2007/10/02)
The reaction of dilithium benzophenone and the lithium salt of benzophenone ketyl with anhydrides and chlorides of benzoic and acetic acid and the reaction of dilithium 9-fluorenone with acetic anhydride were investigated.In addition to the expected products Ar2C(COR)OCOR, products of the type Ar2C=CR(OCOR) were also obtained, and in the case of reactions with acetyl chloride and acetic anhydride, products of the type Ar2CH(OCOR).ESR studies showed that ketyl is formed in the reaction of dilithium benzophenone with acetic anhydride, and the ClDNP method revealed thatbenzhydryl acetate is formed, at least in part, by hydrogen transfer to a free radical produced by O-acetylation of the ketyl.The results suggest a competition between addition and electron transfer reactions.
