    Abstract: THERE IS PROVIDED A PROCESS WHEREIN A LOWER ALKYL ESTER OF A FATTY ACID DERIVED FROM NATURAL FATS AND OILS AND A LOWER ALCOHOL CONTAINING 1 TO 4 CARBONS ATOMS IS PRODUCED IN A LOWER SULFUR CONTENT AT LOWER COSTS WITHOUT CAUSING A REDUCTION IN YIELD AND A DETERIORATION IN SELECTIVITY, AS WELL AS A PROCESS FOR PRODUCING AN ALCOHOL WITHOUT REDUCING THE ACTIVITY OF A CATALYST. THE PROCESS COMPRISES THE STEP OF ADSORPTION TREATMENT OF AN ESTER WITH AT LEAST ONE ADSORBENT SELECTED FROM CLAY AND ACTIVATED CARBON. FURTHER ARE PROVIDED A PROCESS FOR PRODUCING AN ESTER WHICH FURTHER COMPRISES ADSORPTION TREATMENT WITH A HYDROGENATING DECOMPOSITION-TYPE ADSORBENT CONTAINING NI AND/OR CU,IN HYDROGEN OR A MIXED GAS ATMOSPHERE OF HYDROGEN AND AN INERT GAS, AND A PROCESS FOR PRODUCING AN ALCOHOL WHICH COMPRISES HYDROGENATION REACTION WITH AN ESTER PRODUCED BY ANY ONE OF THESE PROCESSES AS THE STARTING MATERIAL.

    Abstract: THE PRESENT INVENTION PROVIDES A SOLID ACID CATALYST DEVELOPING HIGH ACTIVITY AND EXHIBITING HIGH DURABILITY IN VARIOUS ORGANIC REACTIONS. THAT IS, THE PRESENT INVENTION PROVIDES A SOLID ACID CATALYST HAVING THE STRUCTURE (A) IN WHICH A HYDROGEN ATOM IS ELIMINATED FROM AT LEAST ONE OF OH GROUPS CONTAINED IN AN INORGANIC PHOSPHORUS ACID, THE STRUCTURE (B) IN WHICH A HYDROGEN ATOM IS ELIMINATED FROM AT LEAST ONE OF OH GROUPS CONTAINED IN AN ORGANIC PHOSPHORUS ACID REPRESENTED BY THE FORMULA (1) OR (2) AND AT LEAST ONE METAL ATOM (C) SELECTED FROM ALUMINUM, GALLIUM AND IRON AND A METHOD FOR PRODUCING AN ESTER, A KETAL OR AN ACETAL BY USING THE SOLID ACID CATALYST; WHEREIN EACH OF -R1 AND -R² IS SELECTED FROM -R, -OR, -OH AND -H IN WHICH AT LEAST ONE OF -R1 AND -R² IS -R OR -OR, GIVEN THAT -R IS AN ORGANIC GROUP HAVING 1-22 CARBON ATOMS.

    Abstract: Die Erfindung stellt eine Verwendung eines festen sauren Katalysators bereit, der eine hohe Aktivität entwickelt und hohe Haltbarkeit in verschiedenen organischen Reaktionen zeigt. Das heisst, die Erfindung stellt eine Verwendung eines eines festen sauren Katalysators mit der Struktur (A), in der ein Wasserstoffatom aus mindestens einer OH-Gruppe, die in einer anorganischen Säure des Phosphors enthalten ist, entfernt wird, der Struktur (B), in der ein Wasserstoffatom aus mindestens einer OH-Gruppe, die in einer durch die Formel (1) oder (2) dargestellten organischen Säure des Phosphors enthalten ist, entfernt wird, und mindestens einem Metallatom (C), ausgewählt aus Aluminium, Gallium und Eisen, und ein Verfahren zur Herstellung eines Esters, eines Ketals oder eines Acetals unter Verwendung des festen sauren Katalysators bereit;wobei R1 und R2 jeweils aus -R, -OR, -OH und -H ausgewählt werden, wobei zumindest ein Vertreter von R1 und R2 -R oder -OR ist, wobei -R eine organische Gruppe mit 1 bis 22 Kohlenstoffatomen darstellt.

    IPC: C07C67/08

    Abstract: THE PRESENT INVENTION PROVIDES A PROCESS FOR PRODUCING LOWER ALKYL FATTY ESTERS FROM FATTY ACIDS AND LOWER ALCOHOLS, WHEREIN LOWER ALKYL FATTY ESTERS ARE PRODUCED IN HIGHER YIELD WITH A REDUCTION IN THE AMOUNT OF THE REMAINING FATTY ACIDS. THE PROCESS OF THE PRESENT INVENTION COMPRISES BRINGING FATTY ACIDS INTO CONTACT WITH GASEOUS LOWER ALCOHOLS IN FIXED BED (S) CHARGED WITH A WEAKLY ACIDIC SOLID CATALYST BY COUNTERCURRENT OPERATION, BY CO-CURRENT OPERATION AND SUBSEQUENT COUNTERCURRENT OPERATION OR BY PSEUDO-COUNTERCURRENT OPERATION, THUS FEEDING AND REACTING THE FATTY ACIDS AND LOWER ALCOHOLS IN FIXED - BED REACTOR (S) CHARGED WITH A WEAKLY ACIDIC SOLID CATALYST TO PRODUCE LOWER ALKYL FATTY ESTERS.
