Abstract
In the earlier papers reporting the mass-spectrometric type-analysis of paraffines, the objects were confined in C6C11 normal-paraffines or iso-paraffines with only one branch.
The author presents in this paper the mass-spectra of C6C22 paraffines obtained by a mass-spectrometer of high resolving power with a high temperature sample introduction device.
The results indicate that the type analysis with the combining use of the total sum of peakheights of CnH2n ion of M/e>42 (relative values with M/e 57 of n-hexane as the base peak.) and the molecular ion is successfully applicable to C12C22 paraffines.
