1. This effect is reflected in the data of Eglinton, G., Hamilton, R. J., Hodges, R., and Raphael, R. A., Chem. and Indust., 955 (1959); the retention time for cholestanone in a 46-in. column at 220° with an ‘Apiezon’ L-phase was just under 4 hr. Other laboratories have observed shorter retention times under different circumstances (Lipsky, S. R., private communication).
