Abstract: A METHOD AND AN APPARATUS ARE DISCLOSED FOR PREPARING PHTHALIC ACID-GLYCOL MIXTURES FOR ESTERIFICATION. A PROBLEM WHICH IS FREQUENTLY ENCOUNTERED IN PREPARING SUCH PASTE IS THE RETENTION OF THE HOMOGENEOUSNESS OF THEIR COM POSITION, ESPECIALLY IN CONTINUOUS ESTERIFICATION INSTALLATIONS. CONTRARY TO WIDELY ACCEPTED AND WELL ESTABILSIHED TECHNICAL VIEWS, IT HAS BEEN DISCOVERED THAT, BY KEEPING THE MIXTURES OR PASTES AT A COMPARATIVELY LOW TEMPERATURE, THE PREFERRED RANGE BEING BETWEEN 35*C. AND 20* C. THE PROBLEMS INDICATED ABOVE, AND OTHERS CONNECTED THEREWITH, ARE HAPPILY SOLVED AND THE UNDESIRABLE FORMATION OF LUMPS AND INCRUSTATIONS IS EFFETIELY PREVENTED.
