摘要： Disclosed is a method for the catalytic hydrogenation of methylol alkanals of general formula (I), wherein R1 and R2 independently represent an additional methylol group or an alkyl group with 1 to 22 C atoms, or an alkyl group with 1 to 22 C atoms, or an aryl group or aralkyl group with 6 to 33 C atoms, in the liquid phase on a hydrogenation catalyst. The inventive method is characterized in that a pH value ranging between 6.3 and 7.8 is adjusted in the hydrogenation feed by adding at least one tertiary amine.

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.
