Benzenamine, 4,4'-methylenebis[N-ethyl-], also known as N,N'-ethylenebis(N-ethylaniline) or DEBA, is an organic compound with the chemical formula C16H22N2. It is a colorless to pale yellow liquid that is soluble in organic solvents and has a molecular weight of 242.36 g/mol. DEBA is primarily used as a curing agent for epoxy resins, enhancing their mechanical properties, thermal stability, and chemical resistance. It is also employed in the production of polyurethane foams, adhesives, and elastomers. Due to its potential health risks, including carcinogenicity and reproductive toxicity, DEBA is classified as a hazardous substance, and appropriate safety measures should be taken during its handling and use.

843-29-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 843-29-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 843-29:
(5*8)+(4*4)+(3*3)+(2*2)+(1*9)=78
78 % 10 = 8
So 843-29-8 is a valid CAS Registry Number.

A Novel and Convenient Route to (1H-1,2,4-Triazol-1-ylmethyl)phenols, Anilines, N-Alkylanilines and N,N-Dialkylanilines

Katritzky, Alan R.,El-Zemity, Saad,Lang, Hengyuan

, p. 1813 - 1822 (2007/10/02)

Phenols, naphthols, anilines, N-alkylanilines and N,N-dialkylanilines are readily alkylated by 1-hydroxymethyl-1,2,4-triazole to afford the corresponding triazole derivatives in good yields.

Effect of Substituents on the Reaction of Aromatic Amines and Formaldehyde in Acid Medium

Nayar, Mazhuvadyil R. Gopinathan,Francis, Joseph D.

, p. 776 - 780 (2007/10/02)

The kinetics and mechanism of the condensation of N- and C-substituted aromatic amines with formaldehyde in acid medium have been studied using quantitative TLC technique, and the first order rate constants and relative reactivities calculated.In all cases where para-position is free, 4-aminobenzyl alcohols are the initial products.These undergo condensation with amines to give 4-(4-aminobenzyl)anilines.The effect of substituents on the reactivity of amines has been discussed.

Alkylidene Transfer from Monochloroalkylmercury(II) Compounds to Aromatic Amines; Selective C-Alkylation

Barluenga, Jose,Campos, Pedro J.,Roy, Miguel A.,Asensio, Gregorio

, p. 1420 - 1426 (2007/10/02)

αα-Diarylalkane derivatives have been synthesized from monochloroalkylmercury(II) compounds in a noncarbenoid alkylidene transfer reaction which takes place selectively on the aromatic ring.A mechanism is suggested for this process.Intermediate products are prepared by alternative routes to ascertain their participation in the course of the reaction.As a consequence, two different aryl groups can be successively incorporated into the alkane molecule.
