- 論文の詳細を見る
To identify the compounds in machine cutting-fluid emulsion that have an obnoxious odor, we separated volatile components from the emulsion using both steam distillation with a Nickerson-Likens apparatus and vacuum distillation. These components were analyzed by gas chromatography and gas chromatography-mass spectrometry using a fused silica capillary column coated with cross-linked 5% phenylmethyl silicone. 2,6-Dimethyl-3-methoxypyrazine was detected. The main odorous compounds were dimethyl disulfide, dimethyl trisulfide, and 2-butene-1-thiol, the last compound being tentatively identified by its mass spectrum.
