Abstract
Inventia se refera la un pocedeu pentru obtinerea alcoolilor cu continut redus de compusi de azot prin hidrogenarea esterilor alchilici ai acizilor carboxilici obtinuti din olefine, oxid de carbon si alcanol, în prezenta unor catalizatori continînd cobalt si un compus de piridina, conform caruia în scopul îndepartarii compusilor cu azot, esterii respectivi se hidrogeneaza în prezenta unui catalizator de cromit de cupru, la temperaturi de 150...230 degree C si presiune de 200...400 at, dupa care produsul obtinut se trateaza cu un schimbator de ioni acid constînd dintr-un copolimer sulfonat de stiren-divinilbenzen sau copolimeri ai acidului acrilic cu divinilbenzenul.
