Phenol is weakly acidic; in an aqueous solution, deprotonation can occur to form a phenoxide anion and a hydronium ion. This is shown below: Phenol is, however, more acidic than a typical alcohol such as ethanol. This can be explained by the presence of the benzene ring. The acidity of ...
The involvement of oxide radical anion .O is proposed at pH 12. Under highly acidic or basic conditions, colored oligomers are formed as a results, at least in part, of direct photolysis. In the presence of TiO2 the colored oligomers are readily degraded, while in the absence of TiO2 the...
Phenol is an antiseptic and disinfectant. It is active against a wide range of micro-organisms including some fungi and viruses, but is only slowly effective against spores. Phenol has been used to disinfect skin and to relieve itching. Phenol is also used as an oral analgesic or anesthetic ...
Phenol is weakly acidic and reacts with base to form salt. It appears blue when being dissolved in ferric chloride solution. View all 2.13 Physical Properties Phenol is a colorless or white crystalline solid that is slightly soluble in water. Phenol is thesimplest of the large group of ...
The highly selective alkylation at the ortho position of phenol was caused by the dissociative adsorption of phenol; it was discussed by taking account of the acidic and the basic properties of the ZnO–Fe2O3 catalyst. T Kotanigawa,K Shimokawa - 《Bulletin of the Chemical Society of Japan》...
Mildly acidic, it requires careful handling because it can cause chemical burns. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 billion kg/year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to m...
The hydrolysis under basic/acidic conditions was also studied. In addition to grafting, the charring of sunflower stem was studied at 400°C. Our results showed that the optimum condition for grafting was sunflower stem: monomer = 1:3, at 30°C, weight of Fe2+/2 g bleached sunflower ...
