Pseudo-eleostearic Acid

Abstract

Acetophenone can be selectively hydrogenated in isopentane solution to a 70% yield of cyclo-hexylmethylcarbinol1 but the conditions must be controlled carefully.

Ultraviolet Absorption Spectra of Linseed Oil: Determination of Bodied-in-Vacuo and Blown Linseed Oil in Mixtures with Raw Linseed Oil

“…Quantitative measurements of the blown or heatbodied oil were then made by using the relatively high absprption maxima at 2320 A. I N D U S T R I A L A N D E N G I N E E R I N G C H E M I S T R Y Vol. 13,No. 11 The curves presented in Figure 1 relate only to linseed oil produced for this study and were bodied i n vacuo at 307' C.…”

“…This evidence is in support of Brod et al (3) and of Scheiber (20) who presented similar hypotheses. Increased absorption of ultraviolet radiation in connection with prolonged heating on saponification has also been shown to occur (6,7, 9,13,17). In this connection, the absence of any absorption band in the region of 2700 A. in the bodied-in-vacuo oils must be taken as evidence that no systems of three conjugated double bonds are present.…”

Comparative rates of oxidation of isomeric linolenic acids and their esters

“…The pseudo-eleostearic acid (10-12-14 octadecatrienoic acid) was made by isomerizing the linseed oil acids with 20% KOH in ethylene glycol according to the methods of Kass and Burr (6). Its m.p.…”

Liquid C‐18 saturated monocarboxylic acids‐their preparation, characteristics, and potential uses

“…Compounds of type [ are known to be formed by the alkaline isomerization of linolenic acid (16). Furthernlore a compound of type IV is formed if the alkaline isomerization is contiuued at elevated temp (14).…”
