Abstract
Process for preparing dichloroanilides, characterized in that a dichloroaniline is reacted with an excess of a carboxylic acid having 3 to 5 carbon atoms, at a temperature of 150º C to about 155º C, to distill an azeotropic mixture of said acid and water obtained as a by-product; maintaining said temperature for a sufficient time to convert from about 80 to 90 percent of the dichloroaniline; cooling the reaction mass to approximately the boiling point of the anhydride of said acid; slowly adding said anhydride until the content of free dichloroaniline is less than 0.5%; and then heating said reaction mass under reduced pressure, to remove the free carboxylic acid.
