BESTIMMUNG DER AROMATEN IN DEN KOHLENWASSERSTOFFEN DURCH SPEKTROMETRIE IM NAHEN INFRAROT
摘要
Mid-distillate hydrocarbon fuels, preferably having initial boiling points above 350 DEG F., are separated e.g. by prep-HPLC into non-aromatic and aromatic fractions which are used to set 0% aromatics (the non-aromatics) and 100% aromatics (the aromatics) on an NIR spectrophotometer. From NIR aromatic band absorbances of unknown samples, their percent aromatics is determined using this two-point calibration and the Beer-Lambert equation. Preferred NIR bands of 1650-1700 and 2120-2256 exhibit excellent correlation with aromatics content.
