    Abstract: LIGHT-COLORED, COLOR-STABLE FATTY ACIDS OF 8-18 CARBON ATOMS ARE PRODUCED BY HEATING THE CRUDE FATTY ACIDS IN THE PRESENCE OF VANADIUM OXIDE, A LOWER ALKYL VANADATE, A LOWER ALKYL ESTER OF ZIRCONIC ACID, AN AROMATIC CARBOXYLIC ACID OR LOWER ALKYL ESTER THEREOF, OR A MIXTURE OF THE AROMATIC CARBOXYLIC ACID OR ESTER WITH THE ALKYL ESTER OF TITANIC OR ZIRCONIC ACID AT ABOUT 180*-260*C., AND THEN DISTILLING, THE RESULTING MIXTURE UNDER A VACUUM.

    Abstract: 1. A PROCESS FOR THE PREPARATION OF HEAT-RESISTANT AND LIGHTFAST FATTY ACIDS FROM CRUDE FATTY ACIDS HAVING A CHAIN LENGTH OF C8-C18 WHICH COMPRISES HEATING THE CRUDE FATTY ACIDS OR THE MIXTURES THEREOF WITH A POLYCARBOXYLIC ACID SELECTED FROM THE GROUP CONSISTING OF AN ALIPHATIC POLY- OR HYDROXYPOLYCARBOXYLIC ACID CONTAINING 2 TO 10 CARBON ATOMS, AND A CYCLOALIPHATIC POLYCARBOXYLIC ACID CONTINING 5 TO 10 CARBON ATOMS OR A LOWEER ALKYL ESTER OF SAID POLYBOXYLIC ACID TO TEMPERATURES OF ABOUT 180* C. TO ABOUT 280*C., FOR A PERIOD SUFFICIENT TO IMPROVE THE HEAT-RESISTANT AND LIGHTFASTENESS OF THE FATTY ACIDS AND SUBSEQUENTLY DISTILLING OFF THE FATTY ACIDS UNDER A VACUUM.
