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://sentencedict.com/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.
