A catalyst composition for preparing acid amide includes an aminoacid ionic liquid having a cation represented by the formula (I) (wherein R.sub.1, R.sub.2, and R.sub.3 are defined in the specification) and an anion composed of groups consisting of one or more inorganic acid groups, organic acid groups or a combination thereof, wherein the numbers of the cation and anion are capable of allowing the aminoacid ionic liquid to form electro-neutrality; and Bronsted acid. The invention also provides a method for preparing acid amide under the existence of the catalyst composition. The method has advantages of reducing the viscosity of ionic liquid and increasing ketoxime conversion rate and amide selection rate. |
