Abstract
Prezenta inventie se refera la un procedeu de hidrogenoliza a dietilenglicolului, prin scindarea dietilenglicolului la o legatura covalenta carbon-oxigen, la temperatura de reactie cuprinsa între circa 150 degree C si circa 350 degree C, hidrogenul molecular fiindintrodus în reactie sub presiune cuprinsa între circa 18 kg/cm2 si 211 kg/cm2, prin care, în scopul obtinerii a cel putin unuia dintre minoetilenglicol si etanol cu selectivitati de minimum 50% molar, dietilenglicolul reactioneaza cu hidrogenul mole cular în prezenta unor catalizatori în proportie de 0,01...0,5% în greutate, raportata la cantitatea totala a amestecului de reactie, cuprinzînd compozitii ce contin oxid cupros si trioxid de crom cu sau fara oxid de bariu sau oxid de mangan, rodiu si calciu, paladiu si molibden sau compozitii ce contin cel putin unul dintre tungsten, fier, cobalt, platina, reniu, tantal sau zinc.
