Carbon black is another of the carbon-intensive materials. It is formed from the burning of gaseous or liquid hydrocarbons under conditions where the amount of air is limited. Such burning favors soot formation, i.e., carbon black formation. It was produced by the Chinese over 1000 years ago. Today, it is produced in excess of 1.5 million tons annually in the United States. Furnace black is the most widely used carbon black. The particle size of this raw material is relatively large, about 0.08 mm. It is soft with a Mohs scale hardness of less than one.

GT-Styrene Recovery A process for recovering styrene from hydrocarbon fractions obtained by the steam cracking of petroleum. It uses extractive distillation with a proprietary selective extractant. Developed by GTC Technology (formerly Glitsch Technology Corporation) and planned for installation at a Chinese oil refinery in 2007. 

The potential for mutagenic effects was determined in bacterial, fungal, and mammalian cell systems in vitro. Although chrysene produced negative results in Escherichia coli and Saccharomyces, it produced positive results in S. typhimurium in TAIOO. In mammalian cells, chrysene produced positive effects in Syrian hamster embryo cells in vitro. Administration of chrysene to Chinese hamsters by intraperitoneal injection also produced increased sister chromatid exchanges in bone marrow cells. Increased aberrations were also noted in phase II oocytes collected from NMRI mice treated orally with chrysene. Chrysene induced aryl hydrocarbon hydroxylase in cultured human lymphocytes.

Bicyclo[3,14]heptanes.— The structure of paeoniflorin (338), a monoterpenoid glucoside that is the major principle from Chinese paeony root Paeonia albiflora), has been confirmed by X-ray analysis of a bromo-derivative. It is accompanied in the plant by albiflorin (339). ° The crystal structure of bis-(7r-pinenyl)nickel has been given as an example of the use of automated X-ray structural determination as an analytical method. The conversion of the pinenes into other monoterpenoid hydrocarbons continues to produce many publications e.g. conversion...
