Zusammenfassung:The present invention relates to the preparation of incorporated photographic amides. More particularly, the present invention relates to the preparation of incorporated photographic amides using a continuous process. This invention relates to a method of making an incorporated photographic amide comprising a) continuously combining an amine capable of forming an incorporated photographic amide, an acid chloride, one or more acid-absorbing reagents, and one or more water-immiscible solvents to continuously form a reaction mixture; b) continuously reacting the amine and acid chloride to form an incorporated photographic amide; and c) separating the incorporated photographic amide from the reaction mixture.
