Abstract
GLYCIDYL ESTERS ARE PREPARED TO HAVE LOW CHLORINE, CHLORIDE, SODIUM AND POTASSIUM CONTAMINATION AND A THIXOTROPIC INDEXGREATER THAN 3.0 BY A PRECESS THAT COMPRISES REACTING CARBOXYLIC MONO - OR DIMER ACIDS WITH GLYCIDYL ALCOHOLS IN A MOLAR RATIO OF 1 TO 0.9 - 2.0 USING CARBODIIMIDE AS THE ACYLATING AGENT AND A PYRIDINE - CATALYST. THE PYRIDINE - TYPE CATALYST IS REMOVED BY STRONGLY ACIDIC ION EXCHANGE.
