Electric Literature of 33282-15-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 33282-15-4, 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, introducing its new discovery.
A N – methyl anisidine preparation method (by machine translation)
The invention discloses a N – methyl anisidine preparation method, to anisidine and methanol as the reactant, a composite metal oxide A a B as catalyst, the reaction temperature 200 – 350 o C, the liquid volume airspeed is 0.1 – 2.0 h- 1 , N2 Under the condition of the gas as the carrier gas in a fixed bed continuous flow reactor reaction to obtain N – methyl-P-anisidine; composite metal oxide A a B A representative in the catalyst active component CuO – ZnO – NiO or CuO – ZnO – Cr2 O3 , The representative Al B surface coating2 O3 , SiO2 , TiO2 Or a material in the C; Cu and Zn molar ratio of 0.1 – 10:1, cu with Ni molar ratio of 0.1 – 10:1, cu with Cr molar ratio of 0.1 – 10:1; Al the surface coating2 O3 , SiO2 , TiO2 Or C material accounts for the total amount of catalyst 1 – 10 wt %. The invention has simple operation, mild condition, catalyst performance is stable, high yield, low cost, low pollution. (by machine translation)
