Title: CO2 Capture Using 2,2-Dialkylpropane-1,3-diamines

Abstract

A series of 2,2-dialkylpropane-1,3-diamines were synthesized and evaluated as potential phase-changing CO2 sorbents. In general, these compounds readily absorbed CO2 to form solid carbamate salts, which were relatively insensitive to the presence of moisture. This is one of the key performance attributes phase-changing sorbents must possess. However, these diamines were found to be less thermally stable in air than expected. The main reaction products obtained during heat aging at 150 degrees C appeared to be 1,4,5,6-tetrahydropyrimidine derivatives.

  • The antiradical activity of certain polyphenyl oxide diamines in the liquid-phase oxidation of ethyl- and isopropylbenzene was studied. The kinetic parameters of the antiradical activity were determined by chemiluminescent and gasometric methods. The data obtained indicated that polyphenyl oxide diamines, used as monomers for polycondensation, may serve as oxidation inhibitors.
  • Previously reported was a novel analytical method for the determination of 1,2-diaminoethane dinitrate. This method was based on potentiometric titration with standard cupric solution near pH 9. Electromotive forces were monitored with a copper ion-selective indicator electrode and a single-junction reference electrode. In this paper, researchers have extended this work to other diamines, their salts, and polyamines.
  • The purpose of this research was to employ diamines and their quaternary derivatives as carrier molecules for gamma-emitting radiation. The diamine putrescine is widespread in nature and has been reported to selectively concentrate in the rat ventral prostate and pancreas. This study confirms the selective uptake of radioactivity in the rat ventral prostate, but not in the pancreas, following administration of (14C)putrescine. The radioiodinated analogues of putrescine showed no predilection for either of these organs. On the other hand, radioactivity associated with a radioidinated quaternary derivative (3) was found to accumulate in cartilaginous tissues such as trachea, intervertebral disks, andmore » chondrosarcoma tumor in a manner similar to hexamethonium.« less
