How is coal tar obtained list its uses?
Coal tar: It is obtained as a by-product in the process of making coke.
Though its colour is the same as coke, tar is a highly viscous liquid.
It also has an extremely unpleasant smell.
Coal tar is widely used to manufacture paints, perfumes, synthetic dyes, photographic material, drugs and explosives..
Is coal tar an antifungal?
Coal tar is used in medicated shampoo, soap and ointment. It demonstrates antifungal, anti-inflammatory, anti-itch, and antiparasitic properties. It may be applied topically as a treatment for dandruff and psoriasis, and to kill and repel head lice.
Why is coal gas poisonous?
Poisoning from natural gas appliances is only due to incomplete combustion, which creates CO, and flue leaks to living accommodation.
Is coal tar bad for your hair?
But it might make your scalp more sensitive to the sun. Tar can stay on your skin for 24 hours or longer, and your chances of sun damage go up during that time. If you have blond or other light-colored hair, shampoo with coal tar could make it darker. Treatments with coal tar also can stain clothes or skin.
When coal is burnt which gas is produced?
carbon dioxideBut when coal burns, its carbon combines with oxygen in the air and forms carbon dioxide. Carbon dioxide (CO2) is a colorless, odorless gas, but in the atmosphere, it is one of several gases that can trap the earth’s heat.
What is coal gas write its uses?
a gas used for illuminating and heating, produced by distilling bituminous coal and consisting chiefly of hydrogen, methane, and carbon monoxide. the gas formed by burning coal.
What are the two uses of coal gas?
Coal gas is used in lighting. The gas is also used for heating. Most often than not many people use this gas for cooking. It is used as a fuel.
What are the side effects of coal tar?

Is coal tar good for skin?
Coal tar belongs to a class of drugs known as keratoplastics. It works by causing the skin to shed dead cells from its top layer and slow down the growth of skin cells. This effect decreases scaling and dryness. Coal tar can also decrease itchiness from these skin conditions.
Why coal gas is not used for cooking?
This is because we get coal from dead plants and animals buried in the Earth’s crust millions of years ago. Fossil fuels take a lot of time for their formation. As they are not present in large quantities therefore, we cannot use coal excessively. This is the reason why we do not use coal as a cooking fuel.
What gas is used in natural gas?
methaneThe largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). Natural gas also contains smaller amounts of natural gas liquids (NGL, which are also hydrocarbon gas liquids), and nonhydrocarbon gases, such as carbon dioxide and water vapor.
How is coal gas obtained?
Coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel. Sometimes steam is added to react with the hot coke, thus increasing the yield of gas. Coal tar and coke (qq.
Is coal gas still used?
The main technology being used is coal gasification – instead of burning the fossil fuel, it is chemically transformed into synthetic natural gas (SNG). The process is decades old, but recent rises in the price of gas mean it is now more economically viable.
What is Coke and its uses?
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
Is it safe to use coal tar shampoo daily?
Consumers are warned not to use coal tar shampoos for prolonged periods without asking a doctor and to consult a physician before use if the condition covers a large part of the body.
