METHOD FOR THE HYDRODECOMPOSITION OF AMMONIUM FORMATES IN POLYOL-CONTAINING REACTION MIXTURES.

摘要

Disclosed is a method for removing trialkylammonium formate from methylolalkanes obtained by condensing formaldehyde with a higher aldehyde. The inventive method is characterized in that trialkylammonium formate is decomposed at an increased temperature on a catalyst which is placed on a titanium dioxide support and contains ruthenium in the presence of a gas containing hydrogen. Said method makes it possible to separate the trialkylammonium formate from methylolalkanes produced according to the organic Cannizzaro method and the hydration method.
