Abstract: A PROCESS FOR CONTINUOUSLY PREPARING A COMPOUND WHICH BEARS AT LEAST TWO FUNCTIONAL GROUPS WHICH ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF NITRILE GROUP, CARBOXYLIC ACID GROUP, CARBOXYLIC ESTER GROUP AND CARBOXAMIDE GROUP, COMPRISING THE STEPS OF A) ADDING TWO TERMINAL OLEFINS WHICH BEAR THE FUNCTIONAL GROUPS REQUIRED TO PREPARE THE COMPOUND AS PER A1) CONTAINING AT LEAST TWO FUNCTIONAL GROUPS, IN THE PRESENCE OF A COMPOUND AS PER A3) WHCH IS SUITABLE AS A CATALYST FOR THIS ADDITION AND IS HOMOGENEOUS WITH RESPECT TO THE REACTION MIXTURE TO OBTAIN A MIXTURE COMPRISING A1)A COMPOUND WHICH IS OBTAINED BY MONOADDITION OF THE TWO TERMINAL OLEFINS MENTIONED AND BEARS AT LEAST TWO FUNCTIONAL GROUPS WHICH ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF NITRILE GROUP, CARBOXYLIC ACID GROUP, CARBOXYLIC ESTER GROUP AND CARBOXAMIDE GROUP, A2) A COMPOUND WHICH IS OBTAINED BY POLYADDITION OF THE TWO TERMINAL OLEFINS MENTIONED AND A3) THE COMPOUND WHICH IS SUITABLE AS A CATALYST FOR THIS ADDITION AND IS HOMOGENEOUS WITH RESPECT TO THE REACTION MIXTURE, B) DISTILLING THE MIXTURE OBTAINED IN STEP A) TO OBTAIN B1) THE COMPOUND WHICH IS OBTAINED BY MONOADDITION OF THE TWO TERMINAL OLEFINS MENTIONED AND BEARS AT LEAST TWO FUNCTIONAL GROUPS WHICH ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF NITRILE GROUP, CARBOXYLIC ACID GROUP, CARBOXYLIC ESTER GROUP AND CARBOXAMIDE GROUP, AS THE TOP PRODUCT AND B2) A MIXTURE COMPRISING B2A)A COMPOUND WHICH IS OBTAINED BY MONOADDITION OF THE TWO TERMINALS OLEFINS MENTIONED AND BEARS AT LEAST TWO FUNCTIONAL GROUPS WHICH ARE EACH INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF NITRILE GROUP, CARBOXYLIC ACID GROUP, CARBOXYLIC ESTER GROUP AND CARBOXAMIDE GROUP, B2B) A COMPOUND WHICH IS OBTAINED BY POLYADDITION OF THE TWO TERMINAL OLEFINS MENTIONED AND B2C) THE COMPOUND WHICH IS SUITABLE AS A CATALYST FOR THIS ADDITION AND IS HOMOGENEOUS WITH RESPECT TO THE REACTION MIXTURE, C) SEPARATING THE ENTIRE MIXTURE OBTAINED IN STEP B2) OR A PORTION THREOF BY MEANS OF A SEMIPERMEABLE MEMBRANE TO OBTAIN A PERMEATE AND A RETENTATE, IN SUCH A WAY THAT THE WEIGHT RATION OF COMPONENT B2B) TO COMPONENT B2C) IN THE MIXTURE B2) FED IN STEP C) IS SMALLER THAN IN THE RETENTATE, D) RECYCLING THE PERMEATE OBTAINED IN STEP B2) PARTLY OR FULLY INTO STEP A) AND E) RECYCLING THE PORTION OF THE MIXTURE OBTAINED IN STEP B2) WHICH HAS NOT BEEN SEPARATED IN C) PARTLY OR FULLY INTO STEP A).
