Abstract:
The present invention relates to the continuous production of 2-methylene alkanals in a tube reactor, wherein in the 2-position non-branched alkanals are reacted with formaldehyde under acid-base catalysis in the presence of secondary amines and carboxylic acids under laminar flow conditions.

Claim (Index 1):
A method for producing 2-methylene alkanals of the general formula I wherein R 1  is an aliphatic residue, by reacting alkanals of the general formula II with an aqueous formaldehyde solution in the presence of at least one secondary amine and at least one carboxylic acid, characterized in that the educts are reacted in a liquid/liquid two-phase system, wherein the reaction is carried out continuously within a tube reactor under laminar flow conditions with a Reynolds number of greater than or equal to 10 and less than or equal to 2320.
