摘要： A method of determining or predicting a value P x of a property of a material X, which is a feed to a process or a property of a product of a process from said material or yield of said process, which method comprises measuring the absorption D ix of said material at more than one wavelength in the region 600-2600 nm, comparing the said absorptions or a derivative thereof with absorptions D im or derivatives thereof at the same wavelength for a number of standards S in a bank for which the said property or yield P is known, and choosing from the bank at least one standard S m with property P m said standard having the smallest average value of the absolute difference at each wavelength i between the absorption D i x (or derivative thereof) for the material and the absorption D i m (or derivative thereof) for the standard S m to obtain P x , with averaging of said properties or yields P m when more than one standard S m is chosen, and wherein said material X is a composition comprising part of a lubricating oil fraction obtainable from a vacuum distillation of crude oil.
