Abstract: front page image
(DE)Die vorliegende Erfindung betrifft die kontinuierliche Herstellung von 2-Methylenalkanalen in einem Rohrreaktor, wobei in 2-Position nicht verzweigte Alkanale unter laminaren Strömungsbedingungen mit Formaldehyd unter Säure-Base-Katalyse in Gegenwart von sekundären Aminen und Carbonsäuren umgesetzt werden.
(EN)The invention relates to the continuous production of 2-methylene alkanals in a tubular reactor, in which non-branched alkanals at the 2-position are reacted under laminar flow conditions with formaldehyde under acid-base catalysis in the presence of secondary amines and carboxylic acids.
(FR)La présente invention concerne la préparation en continu de 2-méthylène-alcanals dans un réacteur tubulaire, des alcanals non ramifiés en position 2 étant mis en réaction dans des conditions d'écoulement laminaire avec du formaldéhyde sous catalyse acido-basique en présence d'amines secondaires et d'acides carboxyliques.
