In this paper, we discuss the remarkable CO2 absorption properties of a new solvent-free porous organic solid, 1,2-dimethoxyp-tert-butylcalix[4]dihydroquinone. Exposure of 1 to H2 gas at 20 atm did not result in detectable absorption of this gas. High selectivity for CO2 over H2 is a requirement if these materials are to be used for CO2 separations from synthesis gas mixtures exiting, for example, a water-gas shift reactor.

Abstract
In this paper, we discuss the remarkable CO2 absorption properties of a new solvent-free porous organic solid, 1,2-dimethoxyp-tert-butylcalix[4]dihydroquinone. Exposure of 1 to H2 gas at 20 atm did not result in detectable absorption of this gas. High selectivity for CO2 over H2 is a requirement if these materials are to be used for CO2 separations from synthesis gas mixtures exiting, for example, a water-gas shift reactor.File in questo prodotto:
