Carbonaceous material Wet oxidation Phenol Platinum catalyst Catalyst regeneration
2010/9/8
Removal of phenol by wet air oxidation was conducted with 1 wt% Pt/Al2O3 catalyst in a batch reactor and in a continuous flow fluidized bed reactor with air lift tube operated at 423 K and 1.4 MPa. Af...
Interaction between Nitroxide of Hindered Amine Light Stabilizers and Phenol
HALS Phenol Antagonism HALS nitrosonium HALS nitroxide
2009/8/4
The antagonism between nitroxides of hindered amine light stabilizers (HALS NO) and phenolic antioxidants, such as 2,6-di-t-butyl-4-methylphenol (BHT), was investigated. Identification of the reactio...
Extraction of Phenol in Water Phase Using Liquefied Dimethyl Ether
Phenol Extraction Dimethyl ether Aqueous solution
2009/7/23
The applicability of liquefied dimethyl ether (DME) was evaluated as an extractant for phenol, a polar substance, in water. The phenol extraction ratio was 79% from 5.45 wt% phenol solution, and 67% ...
Direct hydroxylation of benzene to phenol
hydroxylation benzene phenol copper-calcium phosphate
2010/8/11
Direct synthesis of phenol from benzene, which could replace the multistage cumene process, is an object of intensive research. We have studied the gas phase conversion of benzene to phenol over bimet...
