| titleOfInvention | Catalyst for synthesizing 2-methyl triethylene diamine and preparation method and application thereof |
| abstract | The invention discloses a catalyst for synthesizing 2-methyl triethylene diamine, a preparation method and application thereof. The catalyst takes Pentasil zeolite as a matrix and is coated with SiO firstly 2 And then loading one or more rare earth metals. The catalyst contains SiO 2 3-30%, rare earth metal 0.3-5%, and Pentasil zeolite 65-95%. The catalyst is applied to the reaction for catalyzing the intermolecular condensation of the ethylenediamine and the 2-methylpiperazine to prepare the 2-methyltriethylenediamine, and the product selectivity can be obviously improved. |
