Products Description of Isomer Separated Mixed Xylene CAS#1330-20-7
This fixed-proportion mixed xylene is configured with standardized isomer content after precise blending and fractionation, specially developed as raw feedstock for fine chemical enterprises’ continuous rectification equipment to separate high-purity single-component xylene. Strict production control keeps the proportion of meta-xylene, ortho-xylene and para-xylene stable in each batch, effectively reducing rectification difficulty and improving finished monomer yield for downstream manufacturers.

Product Application of Isomer Separated Mixed Xylene CAS#1330-20-7
After rectification separation, meta-xylene is core raw material for isophthalic acid production used in high-performance polyester resin; ortho-xylene is applied to produce phthalic anhydride which is essential for plasticizer manufacturing; para-xylene is important precursor material for PTA synthetic industry. We mainly supply bulk cargo via ISO tank for large petrochemical and fine chemical manufacturers, and adjustable isomer component ratio can be negotiated according to long-term bulk clients’ personalized production demands.
