Obiettivo
Together with the nitro PAHs, the oxygenated derivatives are considered to be amongst the major sources of potential carcinogens. More than 50 oxygenated PAHs have been detected, eg in the gaseous effluents from the combustion of brown coal briquettes. PAHs present in drinking water may react with ozone to form oxidized compounds if the conditions of ozonation used for the purification of water are not well controlled. The preparation of a limited number of pure oxygenated PAHs has been undertaken because such compounds are not readily available elsewhere.
RESULTS
The purity of 7 oxygenated PAHs have been certified as follows:
- CRM 337: Dibenzo(b,d) furan 99.0%
- CRM 338: 4H-Cyclopenta(def)phenanthrene-4-one 99.58%
- CRM 339: 6H-Benzo(c,d)pyren-6-one 98.9%
- CRM340: Benzo(b)naphto(1,2-d)furan 99.7%
- CRM341: Benzo(b)naphto(2,1-d)furan 99.64%
- CRM342: Benzo(a)fluorenone 99.79%
- CRM 347: 3-Hydroxybenzo(c)pyrene 99.4%
