Conditions:
Room Temp: 377 - 424 $\pu{K}$
Compiler:
Methodology:
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.
Sample Information:
- Baker Chemical Co.; reagent No. 9011; $n_{D}^{20}$ = 1.3445, $d_{4}^{20}$ = 0.780.
- Synthesized by transesterification of methyl esters and acetates using sodium methanoate as catalyst; purified by gas-liquid partition and thin-layer adsorption chromatography.
Measurement Errors:
Ambient temperature: ±0.5 K.
