Estimating the term…
The invention relates to a method for producing alkaline amides or imides of ethylenically unsaturated C3 to C6 carboxylic acids by reacting amines that contain at least one primary and/or secondary amino group and at least one tertiary amino group with ethylenically unsaturated C3 to C6 carboxlic acids to form an ammonium salt and said ammonium salt is subsequently converted into the alkaline amide or imide by means of microwave radiation, with the proviso that the primary and/or secondary amino group is devoid of alkoxy groups.
A process for preparing a basic amide of an ethylenically unsaturated C3- to C6-carboxylic acid, where the unsaturation is between the alpha and beta carbons of the carboxylic acid, by reacting at least one amine which contains at least one primary and/or secondary amino group and at least one tertiary amino group with at least one ethylenically unsaturated C3- to C6-carboxylic acid to give an ammonium salt, and subsequently converting the ammonium salt to the basic amide or imide under microwave irradiation, with the proviso that the primary and/or secondary amino group does not comprise any alkoxy groups.
