Abstract

believed the accuracy is of the same order of magnitude as that of the synthetic samples. LITERATURE CITED(1) Assoc. Offic. Agr. Chemists, "Official Methods of Analysis," 7th ed., 1950.

Separation of 132° to 138° C. Fraction of Petroleum. Bicycloparaffins in Gasoline Fraction of Petroleum

“…Guenther (6) describes the method and its modifications and points out its sources of error and weaknesses. The extraction method is recognized by the official drug standards (11,12) for the analysis of several phenol-containing volatile oils.…”

Hydrocarbons in 126° to 132° C. Fraction of Petroleum

“…The status of this material prior to the present investigation is described in previous papers (4,6). The details of the analysis of the hydrocarbons in the adjacent low'er-boiling fraction of this petroleum are given in another paper (3).…”
