Product applications:

This product is a basic organic industrial chemical.

1,2,4-Trimethyl Benzene (Pseudocumene)  is also a good solvent for the production of H2O2(hydrogen peroxide).

1,2,4-trimethylbenzene (Pseudocumene)  is used chiefly as the raw material for production of trimellitic anhydride, pyromellitic dianhydride.

1,2,4-Trimethyl Benzene (Pseudocumene) could be used as a gasoline additive to improve the performance of gasoline.

1,2,4-Trimethyl Benzene also (Pseudocumene)  could be used as a solvent in coatings industry.

1,2,4-Trimethyl Benzene also (Pseudocumene)  could be used as a solvent in cleaners industry.

1,2,4-Trimethyl Benzene also (Pseudocumene)  could be used as a solvent in printing and inks industry.

1,2,4-Trimethyl Benzene (Pseudocumene)  is also used in the  industry of pharmaceuticals and dyes .

1,2,4-Trimethyl Benzene (Pseudocumene)  is also used in the  industry of medicines (Vitamin E).

1,2,4-Trimethyl Benzene (Pseudocumene)  is also used in the  industry of synthetic resins, 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.
