ABSTRACT:
The arylsulfonyl(alkyl)amides, notably N-(n-butyl)benzenesulfonamide, well adopted as heat-stable plasticizers for polyamides, e.g., nylon 11 and nylon 12, are directly prepared by (a) intimately contacting an arylsulfonyl halide with a stoichiometric excess of both an alkylamine and an alkaline agent, with the alkaline agent being present in aqueous solution, (b) eliminating water and excess alkylamine from the organic phase produced in stage (a), and (c) separating final product arylsulfonyl(alkyl)amide from the residual organic phase remaining after stage (b).
