Terephthalate, isophthalate and 5-sulfoisophthalate on the Metrosep A Supp 15 - 50/4.0 using Inline-Partial-Loop Technique
AN-S-337
en
Aromatic dicarboxylic acids, e.g., terephthalate, isophthalate and 5-sulfoisophthalate, are important monomers in the manufacture of polyesters and alkyd resins. The monomer ratio of the dicarboxylic acids has an enormous influence on polymerization. The separation of the late-eluting components is completed within 15 minutes if a short Metrosep A Supp 15 - 50/4.0 type column is used together with high eluent concentrations and flow rates.
