Abstract: A process for preparing electronics-grade 2,2′-aminoethyoxyethanol by reacting diethylene glycol with ammonia in the presence of a catalyst in a reactor to give a reaction mixture from which a crude 2,2′-aminoethoxyethanol stream is separated off and is purified further by distillation in a pure column, wherein a sidestream comprising electronics-grade 2,2′-aminoethoxyethanol is taken off from the pure column as a result of the diethylene glycol being passed through a filter which ensures a degree of removal of at least 99% for solid particles having a maximum particle size of ≦̸1.5 μm before the diethylene glycol is fed into the reactor, is proposed.
