-
Paragraph 0065; 0066; 0086; 0087, (2017/01/09)
The invention relates to a preparation method of aliphatic carboxylic acid amide. The method comprises the following step: carrying out a reaction on aliphatic carboxylic acid and monoalkylamine or dialkylamine with 1-4 carbon atoms in the presence of ceric oxide. By using the method, aliphatic carboxylic acid amide can be prepared with high yield, and a catalyst shows an excellent catalytic efficiency and reusing stability.

Page/Page column 5, (2010/12/29)
The present invention relates to a process for producing an aliphatic carboxylic acid amide, including the step of reacting an aliphatic carboxylic acid or an alkyl ester thereof containing an alkyl group having 1 to 4 carbon atoms with a mono- or dialkylamine containing an alkyl group or groups having 1 to 4 carbon atoms in the presence of a solid acid catalyst containing titanium oxide as a main component and an oxide or oxides of at least one element selected from elements (except titanium) belonging to Groups 4, 5 and 14 of the long form of the periodic table, wherein the catalyst has an average particle diameter of 2 μm or more. The process for producing an aliphatic carboxylic acid amide according to the present invention has a high reaction efficiency of the reaction of the aliphatic carboxylic acid or alkyl ester thereof with the mono- or dialkylamine, and shows an excellent filtration efficiency in separation of the catalyst.

, p. 285 - 288 (2007/10/02)
Various carboxamides and peptides are prepared in good yields by treatment of free acids and amines in H2O-dichloromethane or aqueous THF with bis(o-nitrophenyl) phenylphosphonate in the presence of tetrabutylammonium hydrogen sulfate or bromide.Carboxylic esters are also successfully converted to amides via carboxylate salts in one-pot.
