“…The free energy of transfer is mainly determined by the alcohol chain length (Table 2). An average increment in z~,ZG ~ of -2.9 kJ/ mole per CH2-group in the alkyl chain of the alcohol is observed which is comparable to literature data (Kinoshita et al, 1958;Shinoda et al, 1963;Somasundaran et al, 1964;Hanssens et al, 1968;Aveyard and Mitchell, 1969). The effect of the chain length of the alkane is small (0.1 kJ/mole, CH2).…”

Abstraet The adsorption of butanol, hexanol, and octanol on alkylammonium clays of different chain length is studied. The adsorption at infinite dilution compares to the distribution of alcohol between alkane and water in bulk solution. The interlamellar phase of the montmorillonite acts as a solvent even more reactive than carbon tetrachloride. Hydrogen bonds probably occur between the OH group of the alcohol and the NH3 + group. The exchange of water by alcohol on the interlamellar alkylammonium ion is the major factor in the transfer process.

The dissolution process of small (initial (equivalent) radius R 0 < 1 mm) long-chain alcohol (of various types) sessile droplets in water is studied, disentangling diffusive and convective contributions. The latter can arise for high solubilities of the alcohol, as the density of the alcohol-water mixture is then considerably less than that of pure water, giving rise to buoyancy-driven convection. The convective flow around the droplets is measured, using micro-particle image velocimetry (µPIV) and the schlieren technique. When non-dimensionalizing the system, we find a universal Sh ∼ Ra 1/4 scaling relation for all alcohols (of different solubilities) and all droplets in the convective regime. Here Sh is the Sherwood number (dimensionless mass flux) and Ra is the Rayleigh number (dimensionless density difference between clean and alcohol-saturated water). This scaling implies the scaling relation τ c ∝ R 5/4 0 of the convective dissolution time τ c , which is found to agree with experimental data. We show that in the convective regime the plume Reynolds number (the dimensionless velocity) of the detaching alcohol-saturated plume follows Re p ∼ Sc −1 Ra 5/8 , which is confirmed by the µPIV data. Here, Sc is the Schmidt number. The convective regime exists when Ra > Ra t , where Ra t = 12 is the transition Ra number as extracted from the data. For Ra Ra t and smaller, convective transport is progressively overtaken by diffusion and the above scaling relations break down.
