Removal of iron pentacarbonyl from gaseous streams containing carbon monoxide
Abstract
Abstract A process for removing iron pentacarbonyl from carbon monoxide feed gas, comprising contacting the gas with a removal agent comprising alkali metal hydroxide in association with a high boiling hydroxylic solvent to form a nonvolatile iron carbonylate salt, and separating the gas from said agent and the salt. Preferably, the removal agent is adsorbed on a porous support such as diatomaceous earth at a concentration of from about 1% to about 40% by weight of the support, and the solvent is selected from one or mixtures of ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 2,2,4-trimethyl-1,3-pentanediol, glycerine, triethanolamine, 1,4-butanediol, 1,2-propanediol, 1,3-butanediol, 2,5-hexanediol, 1-hexanol and 2-hexanol.
