    Abstract The photocatalytic degradation of phenol has been tested primarily with titanium dioxide (TiO2) either alone or in combination with other materials. In this work‚ Mg/Al hydrotalcites prepared by two methods using inorganic (HC) or organic (HS) chemical reagents‚ along with mixed oxides produced by calcination of these products (HCC and HSC) were mixed with titanium isopropoxide to obtain hydroxide-TiO2 compounds (HCC-TiO2 and HSC-TiO2) to test their photocatalytic activity compared with

    Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced
