Original Measurements
Schmid, H. H. O.; Mangold, H. K.; Lundberg, W. O.; Microchem. J. 9, 134-144 (1965).
Variables:
Room Temp: 290 - 307 $\pu{K}$

Method/Apparatus/Procedure:
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.
Source and Purity of Materials:
- Baker Chemical Co.; reagent No. 9011; $n_{D}^{20}$ = 1.3445, $d_{4}^{20}$ = 0.780.
- Methyl, ethyl and butyl esters purchased from Applied Science Laboratories; propyl and hexyl esters, propanoate and butyrate prepared by direct esterification; other esters synthesized by transesterification; purified.
Estimated Errors:
Ambient temperature: ±0.5 K.
