Make Phenol (carbolic acid) from Aniline
In this video we make Phenol from Aniline via the Sandmeyer reaction. Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract. Repeated or prolonged skin contact with phenol may cause dermatitis, or even second and third-degree burns due to phenol's caustic and defatting properties.Inhalation of phenol vapor may cause lung edema.The substance may cause harmful effects on the central nervous system and heart, resulting in dysrhythmia, seizures, and coma.The kidneys may be affected as well. Exposure may result in death and the effects may be delayed. Long-term or repeated exposure of the substance may have harmful effects on the liver and kidneys." There is no evidence to believe that phenol causes cancer in humans.Besides its hydrophobic effects, another mechanism for the toxicity of phenol may be the formation of phenoxyl radicals. Chemical burns from skin exposures can be decontaminated by washing with polyethylene glycol, isopropyl alcohol, or perhaps even copious amounts of water. Removal of contaminated clothing is required, as well as immediate hospital treatment for large splashes. This is particularly important if the phenol is mixed with chloroform (a commonly-used mixture in molecular biology for DNA & RNA purification from proteins).

DNA Extraction by Phenol Chloroform
DNA Extraction by Phenol Chloroform
( www.abnova.com ) - This method relies on phase separation by centrifugation of a mix of the aqueous sample and a solution containing phenol and chloroform, resulting in an upper aqueous phase and a lower organic phase (mainly chloroform). DNA is present in the aqueous phase and can be recovered by precipitation with isopropanol or ethanol. More videos at Abnova ( http ).

Astani Dept: Chlorinated phenol based biocides and the opportunistic pathogen Pseudomonas aeruginosa
Tue, Mar 28, 2011 @ 02:00 PM - 03:00 PM Speaker: Sudeshna Ghosh, University of Michigan Talk Title: Chlorinated phenol based biocides and the opportunistic pathogen Pseudomonas aeruginosa Abstract: Increasing resistance to antimicrobials among bacteria is a growing problem. While antimicrobials are used to treat infections, their use also selects for drug resistant bacteria that elude treatment. Understanding the ecology of antibiotic resistance has been an important part of my research. Recently, I started looking at this problem from a different angle. I am asking if certain biocides, in addition to selecting for resistant bacteria, have other roles, such as increasing the infectivity of pathogens.
