Abstract
POSTUPAK ZA DOBIJANJE KARBOKSILNE KISELINE, koja ima (n+1) atoma ugljenika reagovanjem ugljen-monoksida sa alkoholom koji ima n atoma ugljenika u prisustvu rodijumovog katalizatora naznačen time, što na temperaturi od 100 do 200В°C i pod delimičnim pritiskom ugljenmonoksida od 1 do 20 MPa reaguje alkohol i/ili estar alkohola i karboksilne kiseline sa ugljenmonoksidom u reaktoru za karbonilovanje koji tokom procesa održava tečnu sredinu koja ima 0,1 do 15 mas.% vode, 2 do 20% mas. stabilizatora katalizatora koji je izabran iz grupe koja sadrži kvaternarne amonijumjodide koji imaju formulu u kojima su R i R1 grupe nezavisno izabrane od alkil grupa C1 do C20, 5 do 20 mas.% jodidnog derivata koji odgovara alkoholu, 0,1 do 10 mas.% estra karboksilne kiseline i alkohola, 100 do 1200 ppm rodijumovog katalizatora i karboksilnu kiselinu; i što se karboksilna kiselina izdvaja iz reaktora za karbonilovanje. Prijava sadrži još 4 zavisna zahteva.A process for the production of a carboxylic acid having (n + 1) carbon atoms by reacting carbon monoxide with an alcohol having n carbon atoms in the presence of rhodium catalyst at a temperature of from 100 to 200V ° C and under partial pressure of carbon monoxide from 1 to 20 MPa reacts the alcohol and / or ester of alcohol and carboxylic acid with carbon monoxide in a carbonylation reactor which during the process maintains a liquid medium having 0.1 to 15 wt.% Water, 2 to 20 wt.%. catalyst stabilizer selected from the group consisting of quaternary ammonium iodides having the formula in which the R and R1 groups are independently selected from alkyl groups C1 to C20, 5 to 20% by weight of alcohol-corresponding iodide derivative, 0.1 to 10% by weight carboxylic acid and alcohol esters, 100 to 1200 ppm rhodium catalyst and carboxylic acid; and the carboxylic acid being separated from the carbonylation reactor. The application contains 4 more dependent requests.
