<p>THE INVENTION IS DIRECTED TOWARD A CONJUGATE PROCESS FOR PRODUCING FATTY NITRILES AND/OR AMINES AND PROPYLENE CARBONATES FROM A NATURAL OIL, INCLUDING THE FOLLOWING ZONES: I) ZONE FOR METHANOLYSIS OR HYDROLYSIS OF A NATURAL OIL CONTAINING A TRIGLYCERIDE OF AT LEAST ONE FATTY ACID PRODUCING, ON THE ONE HAND, THE METHYL ESTER OF THE FATTY ACID OR THE FATTY ACID, AND, ON THE OTHER HAND, GLYCEROL, II) ZONE FOR SYNTHESIS OF A FATTY AMINE, INCLUDING THE FOLLOWING STEPS A) OPTIONAL CONVERSION FIRSTLY OF THE METHYL ESTER OF THE FATTY ACID INTO A FATTY ACID VIA HYDROLYSIS OF THE ESTER DERIVED FROM STEP I), FOLLOWED IN B) BY AN AMMONIATION REACTION WITH AMMONIA OF THE ACID OR OF THE FATTY ACID METHYL ESTER OBTAINED FROM ZONE I OR OF THE ACID OBTAINED FROM STEP A), TO FORM A NITRILE, AND THEN IN C) A REDUCTION WITH HYDROGEN OF THE COMPOUND RESULTING FROM STEP B, OPTIONALLY IN THE PRESENCE OF AMMONIA, TO OBTAIN THE CORRESPONDING AMINE, III) ZONE FOR SYNTHESIS OF A POLYOL CARBONATE BY REACTION OF UREA, EITHER DIRECTLY ON GLYCEROL, OR ON A DIOL OBTAINED BY REDUCTION VIA HYDROGENATION OF GLYCEROL, THE REACTION OF THE POLYOL WITH UREA PRODUCING AMMONIA, IV) ZONE FOR RECOVERY OF THE AMMONIA OBTAINED FROM ZONE III, AND ALSO THAT OBTAINED FROM ZONE LLB IN WHICH THE REACTION IS PERFORMED WITH AN EXCESS OF AMMONIA, AND OPTIONALLY THAT OBTAINED FROM ZONE LLC, TO SERVE AS FEED FOR THE AMMONIATION OF STEP B IN ZONE II AND OPTIONALLY THE HYDROGENATION OF STEP C IN ZONE II.</p> |
