Paradichlorobenzene PDCB (CAS 106-46-7, alias 1,4-Dichlorobenzene) is white flaky or particle crystal,insoluble in water,soluble in ethanol,ethyl ether,benzene and other organic solvents. 1,4-Dichlorobenzene (P-DCB or para-dichlorobenzene, sometimes abbreviated as PDB or para) is an organic compound with the formula C6H4Cl2. This colorless solid has a strong odor. The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring. It is used as a pesticide and adeodorant, most familiarly in mothballs in which it is a replacement for the more traditional naphthalene because of its flammability (though both chemicals have the same NFPA 704 rating). It is also used as aprecursor in the production of the polymer poly(p-phenylene sulfide).
Paradichlorobenzene PDCB is produced by chlorination of benzene using ferric chloride as a catalyst.

Application of Paradichlorobenzene PDCB
Disinfectant, deodorant, and pesticide
PDCB is used to control moths, moulds, and mildew. Paradichlorobenzene is widely used as produce mothballs; It also finds use as a disinfectant in waste containers and restrooms and is the characteristic smell associated with urinal cakes. Its usefulness for these applications arises from p-DCB's low solubility in water and its relatively high volatility: it sublimes readily near room temperature. It also can be used as an insecticide for control of fruit borers and ants.Precursor to other chemicals
Nitration gives 1,4-dichloronitrobenzene, a precursor to commercial dyes and pigments. The chloride sites on p-DCB can be substituted with hydroxylamine and sulfide groups.
