Abstract

Riešenie sa týká sposobu přípravy 3-oxa- -pentandialu. Podstatou riešenia je, že na l,5-dihydroxy-3-oxa-pentan (1 mól) sa působí 2 až 10 mólami oxidu mangáničitého monohydrátu v prostředí 20 až 40 mólov acetónu alebo metyletylketónu alebo ich zmesi po dobu 2 až 8 hodin pri teplote 20 až 40 °C. Po ukončení reakcie sa vzniklý produkt oddělí od katalyzátora filtráciou a od rozpúšťadla destiláciou. Spósob přípravy má využitie v organickej chemii a v chemii biopolymérov pri sieťovaní a modifikácii prírodných látok, obsahujúcich primárné amínoskupiny.
