The insoluble matter of coal tar. IV. Coal tar resins [PDF]
AbstractThe So‐called coal tar resins are defined and their preparation from vertical retort tar and pitch is described. The resins are divided into resinols, resinoic acids, resinenes, and resinamines, about 99% consisting of resinenes. The importance of dxygen in these compounds is discussed.

Epidemiological studies indicate that occupational exposure to coal tar may lead to an increased risk of lung, scrotum and skin cancer. Furthermore, studies with laboratory rodents show carcinogenicity of coal tar after dermal application. This effect may be attributable to polycyclic aromatic hydrocarbons (PAH), which are ubiquitous coal tar ...

Abstract Recent work has disclosed that indenols are present in coal tars, but, until the present, no indenol has been isolated or synthesized. The first members of this class of reactive compounds have now been synthesized by catalytic dehydrogenation of indanols at 650° over chromia alumina with nitrogen gas as carrier.

Coal Tar and Ultraviolet Light
Archives of Dermatology, 1961The use of tar preparations in dermatology has been known for many years. Dioscorides described the use of asphaltic tar as a panacea for cutaneous disorders nearly 2,000 years ago. 1 Coal tar was discovered and described by Becker and Serle in 1681, but its application was first specifically mentioned by Fischel in 1894.

THIS well-known book is one of the acknowledged classics of chemical technology. Originally published in 1882, it has now reached its fifth edition. Perhaps nothing could possibly serve to illustrate more strikingly the extraordinary development of chemical industry during the past third of a century than a comparison of the contents and size of the ...
