Xylene Replacement Solvents Manufacturers

Xylene is commonly used as the water-immiscible solvent. Requirements for a xylene replacement in this application are that the solvent must be inert under typical esterification conditions, exhibit a suitable minimum boiling azeotrope with water, have a high auto-ignition temperature and produce resins with the proper molecular weight distribution profile. A mixture of dipropylene glycol dimethyl ether (DPGDME, CAS# 11110%77-4) and an aliphatic hydrocarbon was shown to be a suitable replacement for xylene. DPGDME is a non-HAP, oxygenated solvent that has a suitable boiling azeotrope with water and la compatible with common resin monomers.
