Abstract
Stabilization process for plasticizing esters, characterized in that they originate from the esterification of an alcohol by an acid and contain, in minimal amounts, reaction product of the alcohol with the strong acid used as esterification catalyst and, in addition, by subjecting the ester to a heat treatment under conditions suitable to render harmless the released strong acid by the effect of this treatment, and by separating then from the ester the energetic acid thus liberated.
