Paradichlorobenzene (PDCB) – Manufacturer, Supplier & Exporter | DPRJ Universal

What is the primary use of Paradichlorobenzene (PDCB)?

The primary industrial use of Paradichlorobenzene is as a disinfectant, space deodorizer, and agricultural fumigant, commonly formulated into urinal deodorant blocks and commercial mothballs. Furthermore, it represents a critical monomer feed chemical in the manufacturing process of polyphenylene sulfide (PPS) technical plastics.

What is the molecular weight and chemical formula of Paradichlorobenzene?

The molecular formula of Paradichlorobenzene is C₆H₄Cl₂, and its exact calculated molecular mass is $147.00 g/mol.

Why does Paradichlorobenzene have a high melting point compared to its isomers?

The fact that paradichlorobenzene has high melting point 53.5 °C is attributed to its high structural symmetry as a para-substituted isomer. This structural linearity permits uniform packing arrangements within its crystalline solid form, requiring substantially higher heat values to melt than its meta and ortho equivalents.

What is the Paradichlorobenzene structure and is it aromatic?

The Paradichlorobenzene structure contains a single benzene core with substituted chlorine atoms directly bound on opposite ends (carbon positions 1 and 4). Because it satisfies the Huckel requirement for aromatic stability with a planar ring structure and six delocalized pi electrons, it is perfectly aromatic.

What is the mechanism of action for Paradichlorobenzene as a fumigant or deodorizer?

The basic paradichlorobenzene mechanism depends entirely on its native sublimation trait. It volatilizes from a solid state directly into a heavy aromatic vapor at conventional room temperatures, executing powerful anti-insect action and ambient masking of foul odors.

What is the CAS number for Paradichlorobenzene?

The designated index or paradichlorobenzene cas number globally used to track this specific chemical compound is 106-46-7.

Is Paradichlorobenzene hazardous and what are the handling precautions?

Yes, it is classified as a hazardous chemical compound capable of causing eye irritation and severe throat discomfort upon inhalation, and is tracked as a potential carcinogen over long periods. Safe industrial use mandates rigorous protective gear, heavy industrial hand protection, and operational execution inside well-ventilated chambers or under active exhaust ducts.

What are the key physical properties, such as boiling point and density?

Prominent physical benchmarks include a solid melting phase threshold at 53.5 °C, an ultimate boiling point of 174.0 °C, and a solid crystal density value of 1.25 g/cm³. It is easily identified as a white crystal flake structure possessing a strong, characteristic camphoraceous odor.

Is Paradichlorobenzene soluble in water?

No, Paradichlorobenzene has very low water solubility, but it is soluble in organic solvents.
