1,4-Dichlorobenzene is a colorless or white crystalline (sand- like) material with a mothball odor. It is used as a fumigant to control mildew and mold, and as an insecticide.

What is another name for 1/3 dichlorobenzene?

What does Mclg stand for in water?

maximum contaminant level goal

After reviewing health effects data, EPA sets a maximum contaminant level goal (MCLG). The MCLG is the maximum level of a contaminant in drinking water at which no known or anticipated adverse effect on the health of persons would occur, allowing an adequate margin of safety.

What is dichlorobenzene made of?

1,4-Dichlorobenzene (1,4-DCB, p-DCB, or para-dichlorobenzene, sometimes abbreviated as PDCB 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 paradichlorobenzene poisonous?

Paradichlorobenzene is a white, solid chemical with a very strong odor. Poisoning can occur if you swallow this chemical.

What is the common name of dichlorobenzene?


Preferred IUPAC name 1,4-Dichlorobenzene
Other names 1,4-DCB para-Dichlorobenzene p-Dichlorobenzene p-DCB PDCB Paramoth Para crystals Paracide Dichlorocide
CAS Number 106-46-7

Can Benzene be used as a solvent?

Benzene is a widely used solvent and is present in gasoline, automobile emissions, and cigarette smoke.

What is a good TDS for water?

between 50-150
What is the best TDS level for drinking water? Ans: Generally, the TDS level between 50-150 is considered as the most suitable and acceptable.

What is the MCL for sodium in drinking water?

While there is no drinking water standard for sodium, state and federal agencies recommend sodium levels in water not exceed 20 milligrams per liter (mg/L) for people on very low sodium diets and 270 mg/L for people on moderately restricted sodium diets.

What is the difference between MCLG and MCL?

A MCLG or PHG is a level of a contaminant in drinking water below which there is no known or expected risk to human health. MCLGs are non-enforceable public health goals. An MCL is the highest level of a contaminant that is allowed in drinking water.

How is MCL calculated?

For chemicals that do not cause cancer, an MCLG is established by first converting the safe dose (RfD) to a water concentration. Then this number is divided by five based on the assumption that exposure to the chemical through drinking water represents only one-fifth of the possible exposure to this substance.

Do mothballs contain benzene?

Mothballs are commonly made of naphthalene or para- dichlorobenzene, both of which are toxic to humans.

Why don’t we use mothballs anymore?

Old fashioned moth balls containing naphthalene or paradichlorobenzene were banned in the EU Environmental Protection Agency in 2008 because of their potential risk to human health. Both chemicals can cause ill health by breathing in fumes over time or ingestion which is a serious risk for small children.

Is it safe to breathe mothballs?

The chemicals in mothballs are toxic to humans and pets. People are exposed to the chemicals in mothballs by inhaling the fumes. If you smell mothballs, you are being exposed to these chemicals. Children or pets sometimes mistake mothballs for food or candy and eat them, which can cause serious effects.

How do I get rid of dichlorobenzene?

You can directly remove it by column chromatrography using hexane as eluent and then adding a more polar solvent to get your ketonic product.

Why is benzene not a good solvent?

It is not a good solvent because it is carcinogenic and banned from most good labs. No benzene is a very good solvent, just a pitty it forms a carcinogenic metabolite in the human body. A good solvent for non-polar molecules, organic or otherwise, but would be a bad solvent for ionic and highly polar species.

Is benzene banned in the US?

Benzene has been banned as an ingredient in products intended for use in the home, including toys. Benzene has a sweet, aromatic, gasoline-like odor. Most individuals can begin to smell benzene in air at 1.5 to 4.7 ppm.

Does boiling water reduce TDS?

Can boiling water reduce TDS? Boiling water doesn’t impact the TDS in your tap water. Toxic metals which are present in the water don’t vaporize and can continue to stay in your drinking water making it unfit for consumption.

Can you drink 0 ppm water?

There is absolutely no reason to drink low TDS/ppm or deionized water. If you are concerned about water quality, put the money toward the purchase of an effective drinking water filter that removes harmful contaminants from your water.

What is the best sodium level for drinking water?

While there is no drinking water standard for sodium, state and federal agencies recommend sodium levels in water not exceed 20 milligrams per liter (mg/L) for people on very low sodium diets and 270 mg/L for people on moderately restricted sodium diets. Most of the salt we consume comes from food.

How do you calculate MCL?

MCL can be calculated as the difference between the conducted power levels measured at the transmitting and receiving antenna ports as the reference point, the directional gain of the antenna is not considered when calculating MCL. Coverage can also be expressed by the Maximum Path Loss (MPL) for a radio technology.

Who sets the MCL?

the U.S. Environmental Protection Agency (EPA)
The MCL is established by the U.S. Environmental Protection Agency (EPA). Currently there are fewer than 100 chemicals for which an MCL has been established; however, these represent chemicals that are thought to pose the most serious risk.

What is the difference between MCL and MCLG?

How wide is the MCL?

Superficial layer of MCL runs vertically and has a width of 15 mm, length of 8–12 cm, and thickness of 2–3 mm. The posterior oblique portion of the MCL (posterior oblique ligament) is fused with layer III and closely attached to the medial meniscus and also the tibia (Fig. 5.4).
