Title: Systems and methods for producing nitriles

Abstract

An aspect of the present disclosure is a method that includes a first reacting a molecule from at least one of a carboxylic acid, an ester of a carboxylic acid, and/or an anhydride with ammonia to form a nitrile, where the first reacting is catalyzed using an acid catalyst. In some embodiments of the present disclosure, the molecule may include at least one of acetic acid, lactic acid, and/or 3-hydroxyproprionic acid (3-HPA). In some embodiments of the present disclosure, the molecule may include at least one of methyl acetate, ethyl lactate, and/or ethyl 3-hydroxypropanoate (ethyl 3-HP). In some embodiments of the present disclosure, the anhydride may be acetic anhydride.
