Abstract: The present invention relates to a process for the conversion of 2-aminoethanol to ethane-1,2-diamine and/or linear polyethylenimines of the formula H2N—[CH2CH2NH]n—CH2CH2NH2 wherein n≥1 comprising (i) providing a catalyst comprising a zeolitic material having the MOR framework structure comprising YO2 and X2O3, wherein Y is a tetravalent element and X is a trivalent element; (ii) providing a gas stream comprising 2-aminoethanol and ammonia; (iii) contacting the catalyst provided in (i) with the gas stream provided in (ii) for converting 2-aminoethanol to ethane-1,2-diamine and/or linear polyethylenimines, wherein the average particle size of the zeolitic material along the 002 axis of the crystallites is in the range of from 5±1 nm to 55±8 nm as determined by powder X-ray diffraction.
