sulfuric acid (H2SO4)

a clear, colorless, oily, highly corrosive liquid that generates great heat when mixed with water. An extremely toxic substance, sulfuric acid causes severe skin burns, blindness on contact with the eyes, serious lung damage if the vapors are inhaled, and death if it is ingested. In industry, sulfuric acid is used in the manufacture of fertilizers, dyes, glue, and other acids; in the purifying of petroleum; and in the pickling of metals. Weak solutions of sulfuric acid are used in the treatment of gastric hypoacidity and serous diarrhea. Formerly called oil of vitriol.

On this basis, the 1-tetralone was treated with Br2 water using AcOH and/or H2SO4 as a catalyst.
The effect of H2SO4 concentration on Zn, Fe, Pb, Mn and Cr in residue has been determined using XRF technique.
The metal ions were then eluted with 5 mL of 2 M H2SO4 and determined by ICP-OES, 100% recovery was achieved.
1 g, 98%) was added and the mixture was stirred vigorously for 10 min at room temperature to afford the immobilized H2SO4 on activated charcoal.
AC impregnated with ZnCl2 gave higher yields compared to H2SO4 at both studied temperatures.
In this process, the methanol to sample ratio, reaction time and temperature were varied from 8:1 to 12:1, 30-60 minutes and 60 [degrees]C to 70 [degrees]C respectively while the catalyst loading was kept constant at 12v/v% H2SO4 (Fig.
The residue (silica and tungstic acid) was washed with a small volume of hot (1+99) H2SO4, followed by water; the volume was made up to the mark with deionized water.
1N) H2SO4 The reading obtained after titration against H2SO4 was then multiplied by 6.
