Methods are disclosed of producing and purifying at least one amide. In accordance with one of the methods disclosed herein, the at least one amide is produced by providing an organic liquid comprising at least one oxime, providing at least one catalyst, adding the at least one catalyst to the organic liquid to form a rearrangement mass, wherein the rearrangement mass comprises at least one amide, at least one impurity, and the at least one catalyst, and heating the rearrangement mass to a temperature of at least about 115° C. for a period of time in order to sulfonate, break down and/or reduce the concentration of some of the at least one impurity in the rearrangement mass.
本公开了生产和纯化至少一种酰胺的方法。根据本文披露的方法之一,至少一种酰胺通过提供含有至少一种肟的有机液体,提供至少一种催化剂,将至少一种催化剂加入有机液体中形成重排物质,其中重排物质包括至少一种酰胺、至少一种杂质和至少一种催化剂,并将重排物质加热至至少约115°C的温度一段时间,以磺化、分解和/或减少重排物质中至少一种杂质的浓度。
