Chemical properties: Colorless transparent liquid with strong aromatic odor. Insoluble in water, soluble in ethanol and ether. Uses Meta-xylene is an intermediate for fungicides such as metalaxyl, furalaxyl, bensulfuron, oxadiazine, chlorothalonil, as well as insecticides and miticides such as amitraz, monoformamidine, chlordimeform, and herbicides such as chlorfenapyr and butachlor. Uses: 1. Meta-xylene is mainly used as a solvent for the production of isophthalic acid and then unsaturated polyester resins and coatings. It is also used to produce meta-toluic acid, isophthalonitrile, pharmaceutical lidocaine, oxymetazoline, and new pan-shadow. It can also be used as a raw material and dye intermediate for spices, oil-soluble colorants for color film, etc. Due to the technical difficulty of producing meta-xylene, my country’s production is very small, and both the output and quality cannot meet market needs.
