摘要：

The interaction of limited amounts of H2O and CD3OH with H2SO4 has been quantitatively studied by broad-line H-1 NMR at 4 K. Simulation of broad-line spectra shows that in aqueous sulfuric acid solutions, H2SO4.xH(2)O with x less than or equal to 4, the first ionisation yields the hydroxonium ion whereas HSO4- is such a weak acid that no interaction with water molecules is detected. The results for CD3OH/H2SO4 = 0.52 and 1.02 show that CD3OH is protonated and hydronium ion are formed. (C) 1999 Elsevier Science B.V. All rights reserved.
