143721-40-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143721-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143721-40:
(8*1)+(7*4)+(6*3)+(5*7)+(4*2)+(3*1)+(2*4)+(1*0)=108
108 % 10 = 8
So 143721-40-8 is a valid CAS Registry Number.

The Reactions of Amine, Polyamine and Amino Alcohol Corrosion Inhibitors in Water at High Temperatures

Smith, John R. Lindsay,Smart, Alison U.,Twigg, Martyn V.

, p. 939 - 947 (2007/10/02)

A stainless steel reactor has been used to investigate the reactions of mono-, di-, tri- and tetraamines, amino alcohols and amino ethers in degassed aqueous solution at 240-300 deg C.The predominant reactions involved nucleophilic substitutions, where the amino nitrogen acts as the nucleophile, and not solvolyses.With α,ω-diamines, cyclic and bicyclic amines were formed by inter- or intra-molecular processes.Amino alcohols react by displacement of the hydroxy rather than the amino group.The material balance deficit, however, was generally significant, and it issuggested that the missing materials are polyamines arising from polymerisation that competes with cyclisation.The major product from 1,2-diaminoethane and related polyaminoethanes and ethanolamines is diazabicyclooctane.The kinetics of some of the cyclisations were studied.Reactions of α,ω-diamines and 5-aminopentan-1-ol are first order in reactant.Conversion of 1,4-diaminobutane to pyrrolidine occurs with high selectivity at 240 deg C; in contrast the reactions of the less reactive compounds were less selective, probably due to the formation of polymeric materials.The relative reactivity of the substrates is discussed in detail.
