Analysis of hazardous wastes by fused silica capillary gas chromatography/Fourier transform infrared spectrometry and gas chromatography/mass spectrometry was written by Shafer, K. H.;Hayes, T. L.;Brasch, J. W.;Jakobsen, R. J.. And the article was included in Analytical Chemistry in 1984.Computed Properties of C8H7ClO2 This article mentions the following:
The results of capillary gas chromatog. (GC)/Fourier transform IR (FTIR) and GC/mass spectrometry (MS) analyses of a hazardous waste sample are presented to demonstrate the high chromatog. resolution, sensitivity, and identifications possible by capillary GC/FTIR. Emphasis is placed on the use of wall-coated open tubular columns for GC/FTIR instead of support-coated open tubular or packed columns which have been more commonly used in the past. Of the 44 compounds detected by either technique, 64% were completely identified and 34% partially identified (exact structure not determined) by GC/FTIR, compared with 30% being completely identified and 52% partially identified by GC/MS. For this sample, capillary GC/FTIR anal. resulted in the characterization of 43 compounds, in contrast to only 17 compounds by packed column GC/FTIR. An automated spectral subtraction of water vapor from each sample spectrum improved spectral search results with correct identifications in some cases being made only after the subtraction procedure. In the experiment, the researchers used many compounds, for example, Chloromethyl benzoate (cas: 5335-05-7Computed Properties of C8H7ClO2).
Chloromethyl benzoate (cas: 5335-05-7) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Computed Properties of C8H7ClO2
