气质联用(GCMS)

  • 悬赏金额:25积分状态:已解决
  •   自己进样CASSIFIX(IFF)加仑子醇的原料,33.131 ,34.649,34.737,35.226,35.859 ,35.999,36.213 ,36.604,36.879 ,37.456这些峰不知全部是主要组分还是其中一些是杂质(异构体),请大家帮助逐个确定下!再次感谢大家!

A study was conducted to determine some physico-chemical properties of the test material. The freezing point was less than -25 C according to EEC Method A1. The boiling point/boiling range was 301.5 to 309.5 C at 1010 mbar according to EEC Method A2. The relative density (D420) was 0.98591 according to EEC Method A3. The vapour pressure was 1.5 Pa at 25 C according to EEC Method A4. The surface tension was 54.7 mN/m for a 90% saturated aqueous solution at 19.5 C according to EEC Method A5. The water solubility was 1.1 x 10(-2) g/l at 20 C according to EEC Method A6. The partition coefficient was Log P >3.66 at 21 C according to EEC Method A8. The flash point was 144.5 C according to EEC Method A9. The flammability (in contact with water ) was not flammable under the test conditions according to EEC Method A12. The pyrophoric properties of liquids and solids according to EEC Method A13 = not pyrophoric under test conditions. The explosive properties according to EEC Method A14 = no explosive under test conditions. Autoignition temperature (liquids and gases) was 240 C according to EEC Method A15.

    30.496可能和Hedione有关。

    CASSIFIX(1-Methyl-4-(1,2,2-trimethylbicyclo[3,1,0]hex-3-yl)-2-oxabicyclo[2,2,2]octane)是沸点范围较宽的原料,或者讲不是一个单峰,相关的资料较少,许多是unpublished。

    感谢朱老师提供的资料,这个原料是公开没有多久吗
