12-Hydroxy-cis-9-octadecenoic acid
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/CO
2
, 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.
Source and Purity of Materials:
(1) Baker Chemical Co.; reagent No. 9011.
(2) Not specified.
Estimated Errors:
Solubility: Not reported.
