37. 4 buffer (pH 5.5) for the first 5 min followed by a linear gradient to 50% of a 60/40 methanol/water solution over the next 10 min. Buffers used for the pH-rate profile were MES (4-morpholineethanesulfonic acid). HEPES (N-(2-hydroxyethyl)piperazine-N'-ethanesulfonic acid), EPPS (4-(2-hydroxyethyl)-1-piperazinepropanesulfonic acid), CHES (2-(cyclohexylamino)ethanesulfonic acid), and CAPS (3-(cyclohexylamino)-1-propanesulfonic acid). No buffer catalysis was observed (at 10-50 mM). The rate constants were reproducible to within 3% error. At pH > 10, production of phenoxide can also be monitored spectrophotometrically at 238 nm.
