Abstract

Instalatia se refera la un procedeu de obtinere a aldehidelor prin hidrogenarea olefinelor ca monoxid de carbon si hidrogen în prezenta unui catalizator complex reprezentat de ligand de fosfor rodiu si de fosfor liber, caracterizat prin aceea ca ligandul este o sare de fosfina tertiara monosulfonata cu formula generala: (vezi formula în text) în care R este individual radicalul alchil ramificat cu 3...9 atomi de carbon, fenil, ciclohexil si M supra + este un radical cuaternar de amoniu cu formula generala II: R sub 1, R sub 2, R sub 3, R sub 4 si N în care R sub 1 este H sau alchil cu 1...20 atomi de G, R sub 2 si R sub 3 sunt alchil cu 1...20 atomi de C; R sub 4 e alchil sau aralchil cu 8...20 atomi de C, în cantitate de minimum 4 mol ligand de fosfor per mol de rodiu, reactia având loc la 60...140 degree C la un raport molar H2/CO al hidrogenului gazos fata de monoxidul de carbon 1 : 1...50 : 1 la o presiune totala de minimum 3,5 kgf/cm supra 2, o presiune partiala de CO de 0,07...8,4 kgf/cm supra 2 si o presiune partiala de H2 de 1,05...11,2 kgf/cm supra 2.
