(2) 1-Alcohols (C10-C20),
C10H18O - C20H42O; [class-004a]

Original Measurements
Schmid, H. H. O.; Mangold, H. K.; Lundberg, W. O.; Microchem. J. 9, 134-144 (1965).
Variables:
Ambient temperature: 296 - 347 K
Prepared by:
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:
- Baker Chemical Co.; reagent No. 9011; n(20°C, D) = 1.3445, d(20°C, 4°C) = 0.780.
- Some alcohols obtained from the Hormel Institute and from Lachat Chemicals; all other alcohols prepared by reduction of the corresponding methyl esters with lithium aluminum hydride; purified by gas-liquid partition chromatography.
Estimated Errors:
Ambient temperature: ±0.5 K.
