1. Coal-tar technology could not cope with the huge expansion in the chemical industry that took place after the Second World War.

2. It is an acid produced from coal-tar.

3. Colorings made from coal-tar derivatives.

4. The carbonization properties of coal-tar pitch were modified by supercritical fluid (SCF) extraction.

5. The results show that the fixed carbon in coal-tar pitch modified with activating agent has been increased.http:///coal-tar.html

6. This shows that coal-tar enamel will be widely used in the pipeline protection area of our country in the future.

7. Coal-tar pitch-based carbon microspheres were prepared by adding petroleum pitch using emulsifying pitch-toluene colloidal solution in polyvinyl alcohol (PVA) glycerol solution.

8. Using coal-tar pitches as raw material, the thermal conversion experiments were done in multi - tube well - crucible controlled by programmed heating.

9. The coal-tar resources are aboudant in China and a suitable process of recovering indole is profitable both in economics and society.

10. Benzopyrene (B(a)P) and coal-tar pitch (CTP) are one of the important factors of enhancing incidence and mortality in the taroperating population with professional lung cancer.

11. With the coal production coal-tar oil substitution partial petroleum and the petroleum substitute, will be the trend in the future society development inevitable, the tar market prospect favors.

12. The low temperature coal-tar includes many precious compound, but at the present it is often selled as the liquid fuel in the market, this creates enormous waste to the resources.

13. Separation of benzene and thiophene from coal-tar oil by extractive distillation is modelled by the tri -diagonal matrix method, the results provide a base for designing a thiophene plant.

14. For underwater hull, use antifouling as recommended. Coal-tar bleed through is likely with most topcoats.
