✦ Synopsis

We recently reported' that acctanilide readily sulphonatcs in solutions of sulphuric acid > 70 per cent I& to form I+acetylsulphanilic acid , and noted that the rate of hydrolysis of this latter compound increased with increasing acidity beyond 80 per cent d= sulphuric acid.

Ve have now prepared IGacetylsulphanilic acid and have followed its rate of hydrolysis to 4aminobenzene sulphonic acid between 20 -95 per cent & sulphuric acid at 80, 90 and 1OO'C and

The kinetics of the acid-catalysed hydrolysis of the [(imidazole)4Co(CO3) ] + ion was found to follow the rate law -dln[complex]/dt = k~K[H+]/(1 + K[H+]) in the 25-45 ~ range, [H +] 0.05-1.0 M range and I = 1.0 M. The reaction sequence consists of a rapid protonation equilibrium followed by the one-
