Specification:

Applications:

It is a raw material for organic synthesis. It is used to make 1,3,5-Benzene Tricarboxylic Acid , antioxidant, ethoxyline resin solidifying agent, polyester resin stabilizer, and alkide resin plasticizer. It is used to produce 2,4,6-trimethylaniline for making such dyes as active cobalt blue and K-3R.

Toxicity and protection:

Its toxicity is similar to dimethylbenzene.It irritates the nose and the throat. The highest permitted concentration in air is 125mg/m3. The operation spot should be well ventilated and the operators should wear protection masks.

Packaging, storage and transportation:

170 kg / iron drum or 20 M/T ISO Tank

Fire and insolation should be avoided during storage. It should be separated from oxidants. It should be handled with care to avoid breaking the package. Securely sealed iron barrel no thinner than 1.2mm can be used to pack the product and each barrel should not exceed 200kg. If it is packed in plastic barrels or glass bottles, securely seal the containers before put into wood cases, which should be securely lined inside with inflammable materials and tightly tied outside with iron wires or iron sheets. Each case should not exceed 50kg and be marked with flammable.

Capacity: 5000 M/T per year
