Fries Rearrangement Reaction Of Phenyl Acetate

Photocatalyst is the core of the photocatalytic technology,have already proved that many semiconductor materials have photocatalytic activity.In recent years the development of hardware template method can use pre-forming mesoporous solid and orderly channel structure,soaking the foot of inorganic salt precursor through two or more times to obtain a new mesoporous material,which is a mesoporous oxide material.that have a high crystallization of the hole wall or the hexagonal cubic.The current can stimulate the photocatalytic reaction mainly confined to the UV light source,to develop maximize use of the photocatalytic reaction of sunlight has broad development prospects.In this paper,we have developed a novel way to take the high concentration of precursor to once inject a hard template mesoporous silica KIT-6 channel,to get mesoporous CeO₂/TiO₂ photocatalyst.By XRD,TEM,BET,UV-VIS,and other modem technical analysis to test the institute of mesoporous CeO₂/TiO₂ micro-structure,organization and performance.Combined China's the pollution dyestuff wastewater status quo,this paper on the mesoporous oxide material photocatalytic degradation of performance,for the light to visible light,in the self-made reactor to degrade indigo red.In addition,in this paper we also study photochemical reaction of the reaction, theα-methylstyrene react to acetophenone,respectively inspected the different light sources,different types of light catalyst,the reaction concentration,reaction time,and the catalyst concentration of oxygen flow rate and other factors to generate acetophenone yield and selective effects.Discussion on the reaction mechanism of theα-methylstyrene photochemical react to acetophenone.With the growing the lack of non-renewable resources,solar and renewable energy use has become an important research topic,photochemical reactions are very good prospects for industrial application.
