Experimental Data:   (Notes on the Nomenclature)
Upper critical solution temperature of the binary system acetonitrile + hydroxy acid
t/°CT/KChemical Name
25.0298.212-Hydroxy-cis-9-octadecenoic acid
   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 - 0.3 mm, the amount required for one CST determination is about 0.2 to 2 μL.
