Components:

(1) Nitromethane, CH₃NO₂ ; [75-52-5] NIST WebBook
(2) Hydroxy acids, C₁₈H₃₄O₃ and C₁₈H₃₆O₃; [class-039] NIST WebBook

Original Measurements

Schmid, H. H. O.; Mangold, H. K.; Lundberg, W. O.; Microchem. J. 11, 376-83 (1966).

Variables:

Ambient temperature: 343 and 360 K

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

The synthetic method was used. As described in Schmid, et al.,¹ a microscope equipped with a heating stage was used. The sealed glass capillary, containing (1) and (2), was held on the heating stage by an aluminum slide. The stage was cooled by acetone/CO₂, and heated electrically by a regulating transformer. For capillaries with inner diameter (0.2 to 0.3) mm, the amount required for one CST determination is about 0.2 to 2 μL.

Source and Purity of Materials:

1. Fisher Scientific Co.
2. Not specified.

Estimated Errors:

Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
Pressure: Not reported.
