Methodology:
The synthetic method was used. A Reichert microscope, type RCH, equipped with a heating stage was used as described in Schmid, et al. [1]. The disappearance and reappearance of the interface between (1) and (2) could be observed without difficulty.
Sample Information:
- Fisher Scientific Co.; certified, No. N-98; $n_{D}^{20}$ = 1.3820, $\rho^{20} = \pu{1134 g L-1}$.
- Methyl, ethyl and butyl esters purchased from Applied Science Laboratories; propyl and hexyl esters, formate, propanoate and butyrate prepared by direct esterification; other esters synthesized by transesterification; purified.
Measurement Errors:
Ambient temperature: ±0.5 K.
