13456-78-5 Usage
General Description
N,N,N',N'-Tetrabenzyl-p-phenylenediamine, also known as TBPD, is a chemical compound commonly used as a polymerization inhibitor and antioxidant. It is a diamine that is substituted with four benzyl groups, and it is a white to light brown solid at room temperature. TBPD is soluble in organic solvents and is often used in the production of rubbers, plastics, and adhesives to prevent premature polymerization and degradation. It functions by scavenging free radicals and stabilizing the polymer chains, thereby extending the shelf life and improving the performance of these materials. Additionally, TBPD is utilized as a stabilizer in the production of lubricants and fuels, as well as in the synthesis of pharmaceuticals and agrochemicals. However, it is important to handle TBPD with caution, as it is considered to be a hazardous substance with potential health and environmental risks.
Check Digit Verification of cas no
The CAS Registry Mumber 13456-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,5 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13456-78:
(7*1)+(6*3)+(5*4)+(4*5)+(3*6)+(2*7)+(1*8)=105
105 % 10 = 5
So 13456-78-5 is a valid CAS Registry Number.

Aqueous-mediated N-alkylation of amines
Singh, Chingakham B.,Kavala, Veerababurao,Samal, Akshaya K.,Patel, Bhisma K.
, p. 1369 - 1377 (2008/09/17)
Direct N-alkylation of primary amines to secondary/tertiary amines and of secondary amines to tertiary amines has been achieved in excellent yields by employing alkyl, benzylic and allylic halides in the presence of NaHCO 3 in an aqueous medium at an elevated temperature. Amines of different stereoelectronic nature react with ease with different halides. The selective formation of secondary amines and the formation of three different substituted tertiary amines are some of the interesting features of this methodology. Reaction in an aqueous medium, operationally convenient conditions, excellent yields and innocuous byproducts, and the absence of transition-metal catalysts, expensive bases, solid supports and the formation of undesired quaternary ammonium salts makes this method a green chemical process.
