    摘要: Disclosed is a process for the preparation of primary, secondary and tertiary amines with high conversion and high selectivity via low pressure catalytic hydrogenation of unsubstituted, N-substituted, and N,N-disubstituted amides. Amide hydrogenation is conducted using a catalyst system comprising copper chromite and a nucleophilic reagent, in combination with hydrogen gas. The process allows for production of amines which may be directly used as chemical intermediates in the manufacture of surfactants, quaternary ammonium compounds, bactericides, disinfectants, lubricants, petroleum additives, ion exchange resins and the like, without the need of purification, such as distillation.

    摘要: Disclosed are processes for preparing linear alkylbenzene sulfonic acids and their corresponding salts comprising: (a) treating a linear alkylbenzene with a sulfonating agent, where the linear alkylbenzene is produced by a reaction between an olefin and benzene; and (b) contacting the sulfonation product of (a) with a mixture of a protic reagent and hydrogen peroxide to result in a sulfonic acid/peroxide mixture.
