| Abstract: | Gas chromatography/mass spctrometry (GC/MS) hyphenated technology was used to separate and identify impurities in methyl isobutyl ketone(MIBK). Hydrocarbon impurities were well separated on HP-5 capillary column and then identified by MS. The low boiling point oxycompounds such as acetone and isopropanol were coelueted from the column but positive identification on foe individual compound was still achievable with scan by scan search and mass chromatograph. The GC analysis of the sample by a more polar HP - 20m column confirmed the above identification. The results show the GC/MS technolo- gy is a more rapid, accurate method for separation and identification of MIBK system. |
