Full text of "The chemistry of the coal-tar dyes" See other formats. Coal tar, which is a distillate obtained in the coking of coal (Section ), is a source of an amazing number of aromatic compounds. Some of these are listed in Table , which includes nitrogen, oxygen, and sulfur compounds, as well as hydrocarbons.

    ‘Coal tar and soot were implicated in the elevated skin cancer incidence found in the refining, shale oil, and coal tar industries in the late nineteenth century.’ ‘All of the so-called coal tar or synthetic dyes are derivatives of benzene, an important organic compound capable of combining in an infinite number of ways with radicals and.

About ' Coal Tar' The gripping, TRUE STORY about how corrupt politics and corporate greed are killing America’s children. "This is the true story of two small American cities — Taylorville, Illinois and Morgan City, Louisiana — where the air, water and soil were fouled by coal tar.

I just finished reading the book "Coal Tar". It is a must read for any concerned citizen. It was important to me, as I lived and experienced first hand what the CIPS did in Taylorville, Illinois. My mother is written about in this book as Coal tar compounds book experienced first hand the effects of the coal tar exposure.5/5(6).

Coal tar creosote is used as a wood preservative and water-proofing agent for structures on land and in marine and fresh waters as well as Coal tar compounds book railway crossing timbers and sleepers (railroad ties), bridge and pier decking, poles, log homes, fencing, and equipment for children's : World Health Organization.

The six major classes of compounds of coal-tar creosote include: aromatic hydrocarbons, tar acids/phenolics, tar bases/nitrogen-containing heterocycles, aromatic amines, sulfur-containing heterocycles, and oxygen-containing heterocycles (Table ).

In Canada and the European Union, there is restricted use of coal-tar creosote and there has been a movement toward a total ban of the. Extraction and mechanism for the separation of neutral N -compounds from coal tar by ionic liquids.

Tar acids, phenolic compounds that react with caustic soda to form water-soluble salts, are extracted from coal tar after it has been distilled. Tar bases are the alkaline constituents of distillate oils, remaining after tar acids have been removed. Coal tar is a complex mixture which consists of a variety of compounds with different functional groups and has wi de ranging of molecular weight.

Functional groups with heteroatom in coal tar such as hydroxy groups, imino groups, etc. play a critical role in the pyrolysis of coal tar because they constitute the more polar fraction of the coal tar and stabilize free radicals (Attar and Hendrickson.

used as a marker compound for carcinogenicity of certain coal tar entries. The assertion is that 50mg/kg (%) concentration of BaP correlates to around mg/kg (%) coal tar. Thus, where BaP is less than %, the amount of coal tar is considered low enough for.

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.

The main product from the distillation of high temperature coal tar. A black solid with an approximate softening point from 30 °C to °C. Composed primarily of a complex mixture of mainly three or more condensed-ring aromatic hydrocarbons.

The new books – none of them recommended vitamins produced chemically, whether from coal-tar, petrol, or any other. Few people realize the nature of coal-tar- and hexane-based vitamins.

It must be remembered that such compounds are produced synthetically. CCTR Indiana Center for Coal Technology Research 6 COAL RANK Anthracite coal is a dense, hard rock with a jet- black color & metallic luster. It contains between 86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke.

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. Phenol is the most important toxicant in coal-tar products and is found in antiseptics, creosote, germicides, cleaners, and disinfectants.

The approximate oral acute LD 50 of phenol for most species is g/kg, except for cats, which are more susceptible because of limited ability to form glucuronides and excrete phenols. Phenols are directly corrosive, and ingestion results in oral and upper.

Classes of Compounds. The subject of compound classes in coal tar and creosote was discussed in general terms by McNeil (33). In coal tar, well over individual compounds have been identified, but the components in creosote belong to a relatively small number of chemical classes. Coal tar creosote is a genotoxic carcinogen whose a threshold concentration has not yet been determined.

Coal tar creosote is used as a wood preservative and water-proofing agent for structures on land and in marine and fresh waters as well as for railway crossing timbers and sleepers (railroad ties), bridge and pier decking, poles, log homes.The chemical synonyms and identification numbers for wood creosote, coal tar creosote, and coal tar are listed in Tables through Coal tar pitch is similar in composition to coal tar creosote and is not presented separately.
