This product is a basic organic industrial chemical. 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 C9-C10 aromatic hydrocarbons that are produced by catalytic reforming and splitting of naphtha. The pseudocumene content of reformed aromatic hydrocarbons is as high as over 40%. Fractional distillation will produce pure product of 99% 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:	UN3295
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. Fire should be strictly prohibited during storage and transportation and related fire control regulations should be observed. Adequate fire control equipments should be prepared.

Drum loading: 200 Ltrs (170kgs) per galvanized iron drum,80 drums per 20'FCL, total 13,600kgs.

ISO Tank Loading: 20,000 kgs per 24 CBM ISO Tank.

We hereby stongly recommend that loading by ISO Tank is much more economical and convenient than by drum + container, if our customer can receive the goods from ISO Tank.
