Abstract
Procedeul de obtinere a alcoolului furfurilic prin hidrogenarea furfurolului pe catalizator cupru-cromit, caracterizat prin aceea ca, reactia are loc în prezenta unui amestec de catalizator CuO-Cr2-O3CaO-grafit, si material ceramic asezat în straturi si anume în stratul I raportul catalizator:material ceramic este de 1:2, în stratul II de 1:1, în stratul III de 2:1, în stratul IV de 2,5:1, în sensul circularii amestecului de furfurol-hidrogen, la temperatura de 50...140 degree C si presiunea de 60....65 at, dupa care se adauga monoetanolamina sau hidrat de hidrazina.
