Glass Ball as Bullet Solubility System: Acetonitrile with Aldehydes
Components:
   (1) Acetonitrile; C2H3N; [75-05-8]  NIST Chemistry WebBook for detail
   (2) Aldehydes; C18H34O and C18H36O; []  NIST Chemistry WebBook for detail
Original Measurements:
   Schmid, H.H.O.; Mangold, H.K.; Lundberg, W.O.; Microchem. J. 11, 376-83 (1966).

 Variables:
   Temperature = 284 K and 313 K

 Experimental Data:   (Notes on the Nomenclature)
  
Upper critical solution temperatures of the systems acetonitrile (1) + aldehyde (2)
t/°CT/KChemical Name
11.0284.2cis-9-Octadecenal; C18H34O; [2423-10-1]
40.0313.2Octadecanal; C18H36O; [638-66-4]
 Method/Apparatus/Procedure:
   The synthetic method was used. As described elsewhere,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 - 2 μL.

 Source and Purity of Materials:
