Glass Ball as Bullet Solubility System: Nitromethane with Hydroxy acids

Components:
   (1) Nitromethane; CH3NO2; [75-52-5]  NIST Chemistry WebBook for detail
   (2) Hydroxy acids; C18H34O3 and C18H36O3; []  NIST Chemistry WebBook for detail

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

Variables:
   Temperature = 343 K and 360 K

Prepared By:

Experimental Data:   (Notes on the Nomenclature)
  
Upper critical solution temperatures of the systems nitromethane + hydroxy acid
t/°CT/KChemical Name
70.0343.212-Hydroxy-cis-9-octadecenoic acid; C18H34O3; [141-22-0]
86.5359.712-Hydroxyoctadecanoic acid; C18H36O3; [106-14-9]
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.
