โœฆ Synopsis

Due to mode coupling, the fluctuations in near-critical liquids with temperature gradients differ from equilibrium ones at ลฝ . length-scales r ) r . The mode coupling radius r decreases when the reduced temperature ยดs T y T rT decreases at mc mc c c

ลฝ . a constant temperature gradient, and may coincide, at ยดs ยด=ยด, with the increasing correlation radius r . For ยด-ยด, the cn c cn mode-coupling effect limits the critical range of scales, self-consistently determining both the mode coupling and the correlation radius. Conditions for an experimental test of the theory are discussed.

Quantitative kinetics for the alkylation reactions of phenol and p-cresol with tert-butyl alcohol in near-critical water as a function of temperature are reported. The reaction products of the alkylation reactions were ortho-and para-substituted phenols, which are used extensively as antioxidants in
