    • The reactions of dimethyl ether with and without water are much slower than those of diethyl ether, Actually, we have found that the consumption ratio of diethyl ether is ∼0.6 at 400 °C and 20 h of the neat reaction, whereas that of dimethyl ether is ∼0.3 under the same reaction condition.

    • disp has an uncertainty of ±0.02 at 20 h. With this uncertainty, our arguments are not affected.

    • As is well-known, no singularity occurs for the free energy at the critical point. Only the derivatives may involve singularities.
