Abstract: COMPLETELY ODORLESS ACETOGLYCERIDES, SOLID AT ROOM TEMPERATURE AND HAVING AN EXTRAORDINARY RESISTANCE TO HYDROLYSIS, ARE PREPARED BY ACETYLATING PARTIAL GLYCERIDES OF FATTY ACIDS HAVING 16 AND/OR 18 CARBON ATOMS, THE PARTIAL GLYCERIDES HAVING AN IODINE NUMBER OF BELOW 5 AND A MONOGLYCERIDE CONTENT OF MORE THAN 70% BY WEIGHT, TO A HYDROXYL NUMBER OF AT MOST 30, DISTILLING OFF THE ACETIC ACID AND EXCESS ACETIC ANHYDRIDE AS COMPLETELY AS POSSIBLE, AND DEODORIZING THE REACTION MIXTURE AT A TEMPERATURE OF GREATER THAN 170C. UNDER A VACUUM, WITH AN INERT GAS OR VAPOR BEING PASSED THERETHROUGH.

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.

Abstract: A PROCESS FOR THE PRODUCTION OF ARYL ESTERS OF POLYCARBOXYLIC ACIDS SUCH AS ISOPHATHALIC AND TEREPTHALIC ACID IS DISCLOSED WHICH IS AN IMPROVEMENT IN THE PROCESS DISCLOSED IN U.S. PATENT 3,471,549. THE IMPROVEMENT OF THE SUBJECT PROCESS INVOLVES THE ADDITION OF A CARBONIC ACID DIARYL ESTER IN PLACE OF THE LOWER FATTY ACID ANHYDRIDE USED IN THE PROCESS OF THE PATENT. THE CARBONIC ACID DIARYL ESTER IS ADDED IN AN AMOUNT WHICH IS AT LEAST EQUIVALENT TO THE ALKYL ESTER GROUPS STILL PRESENT IN THE REACTION MIXTURE WHICH CONTAINS THE DESIRED ARYL ESTER OF THE POLYCARBOXYLIC ACID.
