Abstract
Abstract 1. A PROCESS FOR THE PREPARATION OF ORGANIC CARBOXYLIC ACIDS COMPRISING CONVERTING A FORMIC ACID ESTER OF THE FORMULA HCOOR WHEREIN R IS AN ALKYL RADICAL OF 1 TO 6 CARBON ATOMS, AN ALKENYL OR ALKYNYL RADICAL OF 2 TO 6 CARBON ATOMS, OR AN ALICYCLIC HYDROCARBON GROUP OF 4 TO 10 CARBON ATOMS, INTO AN ORGANIC ACID OF THE FORMULA RCOOH WHEREIN R IS AS DEFINED ABOVE, AT A TEMPERATURE OF FROM 100* TO 350*C. AND IN THE PRESENCE OF CARBON MONOXIDE UNDER A PRESSURE OF AT LEAST 80 KG./CM.2 GAUGE WHEREIN THE PARTIAL PRESSURE OF CARBON MONOXIDE IS AT LEAST 50 KG./CM.2 GAUGE, THE CONVERSION BEING EFFECTED EITHER WITH OUT A CATALSYT OR IN THE PRESENCE OF A METAL PER SE BELONGING TO GROUP VIII OR GROUP IIB OR A SALT OR A NONSALT COMPOUND THEREOF ACTING AS A CATALYST, SAID CATALYST BEING PRESENT IN AN AMOUNT OF 0.2-200 MILLIGRAM ATOMS, RECKONED AS THE METAL, PER MOL OF THE STARTING FORMIC ACID ESTER, SAID CONVERSION BEING EFFECTED IN A POLAR ORGANIC SOLVENT.
