تعريف paradichlorobenzene في الإنجليزية الإنجليزية القاموس.

1,4-dichlorobenzene, an organic compound used as a pesticide (for example in mothballs) and a deodorant

1,4-Dichlorobenzene (para-dichlorobenzene or p-DCB) is a white solid with a strong, pungent odor, the characteristic smell of urinal cake. It is an aromatic chemical compound having the chemical formula C6H4Cl2. It consists of two chlorine atoms substituted onto a benzene ring. It is used to control moths, molds, and mildew, and to deodorize restrooms and waste containers. Its primary use is in most modern mothballs in which it is a replacement for the more traditional naphthalene. Trade names for p-DCB include Paramoth, Para crystals, and Paracide reflecting its widespread use as a pesticide to kill moths. p-DCB is also used as a precursor in the production of the polymer poly(p-phenylene sulfide), and is used in urinal deodorant blocks because of its volatility
