What does dichlorobenzene look like?
P-dichlorobenzene appears as a white colored liquid with the odor of moth balls. COLOURLESS-TO-WHITE CRYSTALS WITH CHARACTERISTIC ODOUR. ILO International Chemical Safety Cards (ICSC) Colorless or white crystalline solid with a mothball-like odor.
How many dichlorobenzene exist?
There are three distinct chemical compounds which are dichlorobenzenes: 1,2-Dichlorobenzene or ortho-dichlorobenzene; 1,3-Dichlorobenzene or meta-dichlorobenzene; 1,4-Dichlorobenzene or para-dichlorobenzene.
Is dichlorobenzene an isomer?
Dichlorobenzene, any of three isomeric organohalogen compounds known as 1,2-, 1,3-, or 1,4-dichlorobenzene (also called ortho-, meta-, and para-dichlorobenzene, respectively). Both 1,2- and 1,3-dichlorobenzene are liquids. All three compounds are colourless, denser than water, and insoluble in water. …
What is the chemical formula for P-dichlorobenzene?
C6H4Cl2
1,4-Dichlorobenzene/Formula
1,4-Dichlorobenzene (1,4-DCB, 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.
Is P-dichlorobenzene liquid?
May cause lung damage. Material is a solid at room temperature that melts upon moderate heating into a combustible liquid with a flash point below 200°F(93.3°C).
What is the main use for P-dichlorobenzene?
The primary uses for p-dichlorobenzene are in the manufacturing of plastic material and other chemicals manufacturing and as an odor agent in several products.
Why does P-dichlorobenzene?
(a) p-dichlorobenzene have higher melting point than ortho and meta isomer. This is because the para isomer is higher a symmetrical structure and therefore, its packing is more efficient as compared to the ortho and meta isomer, therefore, it shows higher melting point.
Is Paradichlorobenzene harmful to humans?
The vapor of paradichlorobenzene is toxic to insects. In humans and other animals, paradichlorobenzene is broken down in the body to form other compounds that may be harmful to cells or organs such as the liver.
Why p-Dichlorobenzene has lower solubility?
p-dichlorobenzene is the most symmetrical structures of it’s isomers. ( melting point increases with increase in symmetry.) it fits most closely in the crystal lattice and hence has strong intermolecular bonds. hence it has lower solubility.
Why p-Dichlorobenzene has higher boiling point?
Due to symmetry, para-dichlorobenzene fits closely in the crystal lattice. As a result, intermolecular forces of attraction are stronger and therefore, greater energy is required to break its lattice and its melts at higher temperature.
Why are moth balls banned?
Exposure to naphthalene mothballs can cause acute hemolysis (anemia) in people with glucose-6-phosphate dehydrogenase deficiency. IARC classifies naphthalene as possibly carcinogenic to humans and other animals (see also Group 2B). Mothballs containing naphthalene have been banned within the EU since 2008.
What is the chemical formula for para dichlorobenzene?
What is Para dichlorobenzene? Para dichlorobenzene is a chlorine substituted organic compound with the chemical formula C 6 H 4 Cl 2. Para dichlorobenzene is an aromatic compound forms a number of azeotropic mixtures. Para dichlorobenzene is usually called 1,4-dichloro benzene and also called as para crystals and paracide.
Is there 1, 4 dichlorobenzene in drinking water?
(1) 1,4-Dichlorobenzene has been detected in drinking water at levels ranging from 0.01 to 1.54 ppb. Occupational exposure to 1,4-dichlorobenzene may occur in factories that produce or process 1,4- dichlorobenzene products.
What kind of cancer can 1, 4 dichlorobenzene cause?
A National Toxicology Program (NTP) study reported that 1,4-dichlorobenzene caused kidney tumors in male rats and liver tumors in both sexes of mice by gavage (experimentally placing the chemical in their stomachs). EPA has classified 1,4-dichlorobenzene as a Group C, possible human carcinogen.
How is 1, 4-dichlorobenzene used as an insecticide?
(NCI05) 1,4-dichlorobenzene is a dichlorobenzene carrying chloro groups at positions 1 and 4. It has a role as an insecticide. The primary exposure to 1,4-dichlorobenzene is from breathing contaminated indoor air. Acute (short- term) exposure to 1,4-dichlorobenzene, via inhalation in humans, results in irritation of the skin, throat, and eyes.
