QUANTIFICATION OF CH(N)-PORTIONS IN CRUDE PETROLEUM FRACTIONS -PROBLEMS IN THE USE OF THE DEPT METHHOD
The estimation of CH(n) quantities is useful for construction of more detailed average molecules. The conventional NMR technique DEPT providing the CH(n) values is discussed. Three systematic errors in standard DEPT procedure are described and correction equations (see (21) - (24)) for compensating these errors are given. In addition, a nonsystematic error is described.
