THE PROCESS OF PRODUCING POLYHYDRIC ALCOHOL ESTERS OF FATTY ACIDS HAVING A HIGH MONOESTER CONTENT WHICH COMPRISES HEATING TO A TEMPERATURE OF AT LEAST 200*C. AT LEAST ONE FATTY MATERIAL FROM THE GROUP CONSISTING OF FATTY ACIDS AND FATTY ACID ESTERS WITH 4 TO 10 MOLAR PROPORTIONS OF POLYHYDRIC ALCOHOL WHICH IS NOT MISCIBLE IN THESE AMOUNTS WITH THE REACTION PRODUCT, AGITATING SAID MATERIALS WHILE SO HEATED TO FORM AN INTIMATE DISPERSION OF SAID ALCOHOL AND FATTY MATERIALS, SUBJECTING THE PRODUCT AFTER THE REACTION HAS REACHED SUBSTANTIAL EQUILIBRIUM TO COOLING AGAINST A SURFACE HAVING A TEMPERATURE SOMEWHAT ABOVE THE MELTING POINT OF THE PRODUCT TO REDUCE THE TEMPERATURE OF THE PRODUCT BELOW ABOUT 100*C. WHILE STILL SUBSTANTIALLY MAINTAINING SUCH DISPERSION, AND PERMITTING THE COOLED PRODUCT WHILE STILL LIQUID TO SEPARATE INTO AN ESTER LAYER CONTAINING A MINOR AMOUNT OF DISSOLVED POLYHYDRIC ALCOHOL AND A SUBSTANTIALLY PURE LAYER OF POLYHYDRIC ALCOHOL.
