| titleOfInvention | Method for producing triethylenediamine |
| abstract | The present invention relates to a process for producing triethylenediamine from an amine compound on a zeolite catalyst, wherein a considerable amount of by-product piperazine is separated from triethylenediamine and recycled. SOLUTION: In the molecule, a general formula 1 Amine compounds having moieties (R 1 , R 2 , R 3 , R 4 are independently hydrogen or C 1-4 alkyl, X is oxygen or nitrogen) are passed over the catalyst at elevated temperature A process for producing triethylenediamine to form a reaction product containing triethylenediamine and piperazine, adding one or more nitrogen and / or oxygen-containing ethylating compounds to the reaction product; Contacting the condensed / cyclized shape selective zeolite with a / ethylenediamine incorporation weight ratio under conditions sufficient to form triethylenediamine from the ethylating compound and piperazine. |
