“…For the study of the coinpositioil of essential oils, coluinns which are equally efficient for the separation of oxygenated conlpounds, including isoineric pairs, are required. The separation of the isoineric menthols on either polyethylene glycol (26) or silicone oil (27) Table IV. Though only a relatively small number of oxygenated monoterpenes were studied, the retention data obtained allow conclusions to be drawn as to which column or columns may be suitable for a specific separation.…”

'The separation of several cyclic terpene hydrocarbons and some oxygenated derivatives was s t~~d i e d on a variety of triglyceride and dioleate ester columns. Use of rapeseed oil, partially hydrogenated rapeseed oil, olive oil, triolein, tristearin, methyl oleate, and p o t a s s i~~~n oleate as liquid phases led to the conclusion that the presence of an esterified mono-unsaturated long-chain acid is a desirable constituent of the liquid phase. Dioleate esters of 1,s-propanediol, 1,4-butanediol, 1,6-hesanediol, diethylene glycol, and polyethylene glycol showed useful differences in the degree of separation of both terpene hydrocarbons and oxygenated derivatives. Ether linkages, as in the di-and poly-ethylene glycol ester, also were associated with favorable separations. When the liquid phase contained free hydroxyl groups, the degree of separation of hydrocarbons and ketones was i n general less favorable. The spacing of the ester groups was found to have some effect on retention data. The separation of such critical pairs of isomers as tricyclene and a-pinene, a-fenchene and camphene, and also geometrical isomers of osygenatecl derivatives is facilitated by use of several of these liquid phases.

“…It offers a potential means for relatively rapid and more complete analysis than was formerly possible. Petrowitz, Nerdel, and Ohloff (12) have made an unsuccessful attempt at separating the menthols, using gas chromatography.…”
