Major Uses

For 2-xylene (USEPA/OPP Pesticide Code: 086800) ACTIVE products with label matches. /SRP: Registered for use in the USA but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses./
Manufacture of phthalic anhydride, vitamin and pharmaceutical syntheses, dyes, insecticides, motor fuels.
Chem intermediate for phthalonitrile
Chem intermediate for other derivatives
Reacts with hexafluoroacetone to produce 4,4'-(Trifluoro-1-(trifluoromethyl)ethylidene) diphthalic anhydride, an intermediate in the preparation of high-performance polyimide polymers
Used as a chemical intermediate in the synthesis of: benzophenonetetracarboxylate dianhydride; 4-chloro-o-xylene; hexafluoropropane-2,2-bis(phenyl-3 ,4 -dicarboxylic acid anhydride); pendimethalin; phthalic anhydride; phthalide; phthalodinitrile; o-toluic acid; 2-(trifluoromethyl)benzoyl fluoride; 3,4-xylidine.
CHEMICAL PROFILE: Orthoxylene. Nearly all orthoxylene recovered in the US is consumed in the manufacture of phthalic anhydride. A minor amount is used to make bactericides, soybean herbicides and lube oil additives.
PRODUCT PROFILE: Orthoxylene. Orthoxylene (OX) is the second largest of the three commercial isomers of xylene. Almost all orthoxylene output is consumed in the manufacture of phthalic anhydride (PA), which is used to make plasticizers used in compounding polyvinyl chloride resins, unsaturated polyesters used in glass-reinforced thermoset engineering applications, and alkyd resins used mainly for surface coatings. Small quantities are used in solvent applications (which are declining) and to make bactericides, soya bean herbicides and lube oil additives. A new outlet is in the production of polyethylene naphthalate (PEN) polymer, which is a high performance polyester used in film and rigid packaging where performance needs are more rigorous than polyethylene terephthalate products.
