| Abstract: | A useful and simple proceduce was described for determination of trace fatty acids of C6-C8 in trialkyphosphine oxide by simultaneous pyrolysis and methylation gas chromatography. Tetramethylammonium hydroxide was used as methylation reagent. The FFAP capillary column was used. The recovery of the method is 90%～110%. This analytical method was applied to determination of fatty acids in trialkyphosphine oxide with satisfactory results. |
