Paradichlorobenzene is a white solid with a characteristic penetrating odour. Paradichlorobenzene is also known as 1,4-dichlorobenzene, paradichlorobenzol, p-DCB and PDB. It is produced by the chlorination reaction of benzene in the presence of iron (III) chloride as a synthesis catalyst.
Dichlorobenzenes belong to the group of organic halogen compounds in which two hydrogen atoms in benzene are replaced by chlorine atoms. There are three isomeric forms: para-, ortho- and meta- dichlorobenzene.
From a technological point of view, it is also possible to obtain a molten paradichlorobenzene, which is preferred in the US and Asia.
The product sublimates in contact with air, which results in the release of a strong odour. Due to this feature, paradichlorobenzene is used:
– for production of insecticide fumigants against moths and cloth moths (moth balls),
– as an insecticide and fungicide,
– as a great alternative to more traditional naphthalene due to higher flammability of naphthalene,
– in air fresheners.
The constantly growing market for paradichlorobenzene is specialized plastics, where due to the use of PDCB, materials are more resistant to high temperatures. Due to meeting high quality standards, it can also be used for the production of pharmaceuticals and API (Active Pharmaceutical Ingredients).
The product is packed in 25kg sacks and stored 1 ton on pallets, it is possible to be shipped by curtainsider fleet or containers.
