摘要

Improving the color stability of alkanolamines comprises contacting an alkanolamine with hydrogen in the presence of a catalyst comprising nickel, copper, ruthenium, palladium, silver, rhenium, osmium, iridium or platinum on a support produced by heat treatment of a layered double hydroxide of divalent and trivalent metals.
