Method/Apparatus/Procedure:

The synthetic method was used. A Reichert microscope, type RCH, equipped with a heating stage was used as described elsewhere.1 The disappearance and reappearance of the interface between (1) and (2) could be observed without difficulty.

Source and Purity of Materials:

(1) Baker Chemical Co.; reagent No. 9011; n(20°C, D) = 1.3445, d(20°C, 4°C) = 0.780.
(2) Methyl, ethyl and butyl esters purchased from Applied Science Laboratories; propyl and hexyl esters, formate, acetate, propanoate and butyrate prepared by direct esterification; other esters synthesized by transesterification; purified.

Estimated Errors

Temperature: ±0.5 K.
