Chemicals carbon dioxide

Shipment. The DOT/IMO shipping information is shown in Table 6. Approved materials of constmction for shipping, storage, and associated transportation equipment are lined carbon steel (DOT spec. 105 S 500W) and type 316 stainless steel. Water spray, carbon dioxide, chemical-foam, or dry-chemical fire extinguishers may be used.

Significant progress has been made in alleviating the first two physical causes of membrane instability. The magnitude of the long-term chemical stability problem depends on the process. It is a major issue for carriers used to transport oxygen and olefins, but for carriers used to transport carbon dioxide, chemical stability is a lesser problem.

For liquid dosage forms, altered bioavailability upon storage is generally manifest in precipitation of API or other formulation components. Precipitation can result from a number of factors. With small molecules, precipitation can be caused by shifts in the pH of the solution (suspension). Such shifts can be due to absorption of carbon dioxide, chemical degradation of a component that generates an acid or base or loss of a buffer component due, for example, to oxidation. Another factor with small molecules is precipitation due to an increase in the API particle size. This effect, called Ostwald ripening, is caused by the gradual dissolution of smaller...

Mui et al. (2004) This review presents the current status of research into the production of active carbons from environmental applications using waste tyres. Several activated carbons were produced with BET N2 surface areas >1000m g using steam activation, with values of 270-980m g for activation with carbon dioxide. Chemical activation with KOH produced a carbon with a surface area of 820m g at 850 °C. Models were developed to describe the conversion of waste tyres to a carbonaceous char. Further research is necessary to lead to successful applications of activated carbons from waste tyres.
