Occupational exposures during coal-tar distillation were considered by a previous Working Group in (IARC, ).
Since that time new data have become available, which have been incorporated in this Monograph, and taken into consideration in the present evaluation. Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses.
It may be applied to the affected area to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of ncy category: US: C (Risk not ruled out).
Coal-tar pitch is a thick black liquid that remains after the distillation of coal tar. It is used as a base for coatings and paint, in roofing and paving, and as a binder in asphalt products. Both coal tar and coal-tar pitch contain many chemical compounds, including carcinogens such as benzene.
How are people exposed to coal tar and coal-tar. Distillation of Coal Tar As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonization.
We get coal deep in the earth crust in coal mines. Few industries are more dependent on distillation than that of coal tar. It was in consequence of a discovery by Bethel in that it was realised that valuable products'could be obtained from coal tar by submitting it to distillation.
Since that date the industry has thrived, and every year brings out discoveries of further ingredients in. Coal tar distillates are derived from the distillation of coal tars at coal tar refinery facilities.
They are made of complex combinations of compounds, mainly aromatic hydrocarbons. Their composition varies based on their source, the heating temperature, and the distillation temperature for the distillates.

Coal tar is produced by the dry distillation of coal and is therefore a by product in the manufacture of coal gas. Coal tar pitch serves as a valuable ingredient in the production of a number of water proofing, protective and binding.
It is of this third class of products of the destructive distillation of bituminous coal, much more complex and, perhaps, for that reason much less known than the other two classes, that we wish particularly to speak this evening.
This mixture is known collec- tively under the name of " coal-tar."Author: Samuel P. Sadtler. Coal tar definition is - tar obtained by distillation of bituminous coal and used especially as an industrial fuel, in making dyes, and in the topical treatment of skin disorders.

Coal tar is among the byproducts when coal is carbonized to make coke or gasified to make coal gas. Coal tars are complex and variable mixtures of phenols, polycyclic aromatic hydro carbons, and metro cyclic compounds, about substances in all.
Coal tar is a. Tar and pitch are viscous, dark-brown to black substances obtained by the destructive distillation of coal, wood, petroleum, peat, and certain other organic materials. The heating or partial burning of wood to make charcoal yields tar as a byproduct and is an ancient method for the production of both tar and pitch.
Coal is one of the most useful fossil fuels. It has many applications such as producing heat for households, firing industrial generators, manufacturing cast iron, etc.
It can also be produced in the industry to obtain products like coke, tar and coal gas. These by-products are beneficial to us too. Coal Tar Distillation Products - Pitch is derived from the process of coal Tar at high temperature using the latest technology under strict process and quality control.
The salient features are - (a) Low Volatile content (b) High fixed carbon (c) Low ash content (d) No mesophase (e) Good wettability. Polish coal tar resource base for the production of coal tar pitch for the electrode industry Zbigniew Robak, Teresa Topolnicka.
Scope of presentation 1. Introduction 2. Properties of coal tar produced in Polish coking plant of oil products received during vacuum distillation of coal tar Range of pressure 10 – 50 kPa 80 Dehydration.—The first operation in coal-tar distilling is the removal of the mechanically enclosed water.
Some water is chemically combined with the bases, phenols, &c., and this, of course, cannot be removed by mechanical means, but splits off only during the distillation itself, when a certain temperature has been reached.
