Paradichlorobenzene PDCB (CAS 106-46-7) 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 a deodorant, 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 a precursor 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 pesticidePDCB 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.
