-
, (2019/12/02)
The invention discloses a preparation method of N-dimethylaminopropyl(meth)acrylamide. The preparation method comprises the following steps: firstly, carrying out alcohol derivatization on 3-dimethylamino-1-propanol; reacting the derivatization product with (meth)acrylamide in the presence of an organic solvent and an alkali to obtain the N-dimethylaminopropyl(meth)acrylamide. Compared with a conventional preparation method adopted in the market, the preparation method disclosed by the invention has the advantages that the reaction conditions are mild, the operation is simple and convenient, the control is easy, the preparation cost is relatively low, and the commercial value is relatively high.

Page/Page column 9-10, (2011/05/03)
The invention relates to a continuous method for producing amides, according to which at least one carboxylic acid of formula (I) R3-COON (I), wherein R3 is an optionally substituted alkenyl group comprising between 2 and 4 carbon atoms, is reacted with at least one amine of formula (II) HNR1R2 (II), wherein R1 and R2 are independently hydrogen or a hydrocarbon radical comprising between 1 and 100 C atoms, to form an ammonium salt and/or a Michael adduct, and said ammonium salt is then reacted to form a carboxylic acid amide. under microwave irradiation in a reaction pipe, the longitudinal axis of the pipe being oriented in the direction of propagation of the microwaves of a monomode microwave applicator.
Method For Producing Alkaline (Meth)Acrylamides
-
Page/Page column 8, (2010/03/02)
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.
