ABSTRACT:
A method for removing trialkyl ammonium formate from a methylol alkanes obtained by condensation of formaldehyde with a higher aldehyde. The invention is characterized in that trialkyl ammonium formate is decomposed at a high temperature using catalysts containing at least one metal from groups 8-12 of the classification of elements in the presence of gas containing hydrogen. The method makes it possible to separate trialkyl ammonium formate according to the organic Cannizzaro method and according to the hydrogenation method.
