A PROCESS FOR PRODUCING CAPILARY ACTIVE AMINEAMIDES WHICH COMPRISES CONDENSING AN AMIDE OF A FATTY ACID CONTAINING FROM NINE TO TWENTY-ONE CARBON ATOMS IN ITS ACYL RADICAL AND CONTAINIG A B-HYDROXY ALKANOL SUBSITUTENT ON ITS AMIDE NITROGEN ATOM WITH A COMPOUND SELECTED FROM THE GROUP CONSISTING OF PHOSPHORUS HALIDES AND SULFUR OXYHALIDES, SAID HALIDES BEING SELECTED FROM THE GROUP CONSISTING OF CHLORIDES, IODIDES AND BROMIDES AND WITH A NITROGEN COMPOUND SELECTED FROM THE GROUP CONSISTING OF AMMONIA, COMPOUND DELIVERING AMMONIA AT ELEVATED TEMPERATURES, PRIMARY AMINES, SECONDARY AMINES, AND TERTIARY AMINES, SAID CONDENSATIONS WITH SAID NITROGEN COMPOUND BEING EFFECTED BY REACTING UNDER ATMOSPHERIC PRESSURE AND HEATING TO ELEVATED TEMPERATURES IN EXCESS OF 100* C. BUT NOT EXCEEDING 140* C.
