It is used to make medicines (Vitamin E), dyes, synthetic resins and hydrogen peroxide. It is also used to make trimellitic anhydride, pyromellitic dianhydride, soluble alkide resins, unsaturated polyester resins, plasticizers, ethoxyline resin solidifying agents and surfactants. Manufacture method: It is isolated from the C*-C*0 aromatic hydrocarbons that are produced by catalytic reforming and splitting of naphtha. The pseudocumene content of reformed aromatic hydrocarbons is as high as over *0%. Fractional distillation will produce pure product of *9% or more. Toxicity and protection: This product is toxic and it irritates mucous membrane and central nerves. Avoid contact. Packaging, storage and transportation: DOT Hazard Class: 3 DOT Identification Number: UN***5 DOT Packing Group: III This product is flammable and explosive and should be stored in oil cans, tank trucks or iron barrels which meet the requirement of inspection regulations. Taking expansion into consideration, safety space should be allocated according to temperature variations. Never completely fill the container. to be *****
