On this basis, the 1-tetralone was treated with Br2 water using AcOH and/or H2SO4 as a catalyst.
From XRD results, it is also deduced that at higher concentrations of H2SO4, Zn has highest selectivity in comparison toother metals.
The metal ions were then eluted with 5 mL of 2 M H2SO4 and determined by ICP-OES, 100% recovery was achieved.
Amdur, who directed the work, attributes this "order of magnitude difference' to the fact that the ultrafine size of the ZnO particles helps carry the H2SO4 that they create deep into the lung.
Clearly, the esterification yield of catalysts promoted by (NH4)2SO4 was higher compared with the catalysts impregnated by H2SO4, of which the esterification yield was less than 95 %.
ABSTRACT: Activated carbon (AC1 - AC3) were successfully produced from Moringa oleifera seed pod by chemical activation method (ZnCl2 and H2SO4) at 600degC and 800degC in furnace supplied with nitrogen gas.
Cell: All oxidation processes of n-butanol in H2SO4 were carried out in a two-compartment Pyrex-glass cell.
Airvac systems are sealed, so there is no H2SO4, inflow, infiltration or exfiltration.

2 showed that polarization plots recorded on stainless steel electrode in 1M H2SO4 solution in absence and presence of different concentration of TCDSQ-22 inhibitors at 400.
